Motion Control White Paper – Unlocking the Linear Motion Specification Query

Motion Control White Paper

Understanding the specifications needed to properly size my motion control application –

 

H2W Logo

Santa Clarita, CA —– Every motion control problem begins with a need to move a certain payload over a certain distance. However, there are many types of moves possible, and determining the right motion control solution may require some calculations to match the specifications found on a given motors data sheet. Most sales engineers will ask you for three basic questions when directing you to the proper motor or motion control solution.

What is the stroke or displacement required

What is the force or thrust required?

At what duty cycle do you plan on operating the motor?

Travel Distance

The travel distance is the first piece of information needed to unlock any specification, because a solution to move a few microns would utilize different motion technology from an application requiring several meters of travel. In addition to understanding the total travel required, it would be necessary to determine whether the travel is oscillatory, constant velocity, or the motion profile is defined by a pick-and-place application. Oscillatory systems typically will move back and forth at a specific frequency or range of frequencies. While constant velocity systems either need to operate for a known distance or time at a constant velocity, or they need to get a payload up to a velocity, in these cases the distance and time to accelerate up to the velocity needs to be understood and accounted for in the overall displacement. With this information you can determine the acceleration necessary to make the move. To learn more about calculating acceleration you can read our white paper about calculating acceleration for linear motion.

Force

The next step is determining the amount of thrust or force required. Force is simply the amount of acceleration multiplied by the mass of the moving object. If the motion is horizontal, this equates to the mass of the payload added to the mass of the moving part of the linear motor or stage and multiplied by the amount of acceleration required by the motion. Vertical applications must add or subtract the acceleration due to gravity depending on the direction of motion.

motion control specification formula

Duty Cycle

Finally, how long is power going to be applied to the motor? Many oscillatory systems will be operating continuously, and thus would have a duty cycle of 100%, while other applications will be short bursts of power, 1 second or less, while being off for several seconds, and will have a duty cycle of less than 10%. Duty cycle is defined as the time on divided by the total time per cycle (time on + time off). Depending on the linear motor selected, the amount of force available at a duty cycle of 10% can be as much as 3 times the continuous force rating. This last piece of the puzzle helps break down the necessary components required to properly size any motion control problem.

motion control specification formula - Duty Cycle

Once these three pieces are determined, any application can be sized and verified that it is sufficient based on the specifications found on any standard data sheet.

Quiet 3-to-1 Speed Reducers Using Traction Drive Technology Feature 98% Efficiency!

motion control speed reducer

 

RMI Drives-Logo

North Babylon, NY – Rolling Motion Industries (RMI) has released for production the next two in it’s series of highly efficient speed reducers. These 3-to-1 speed reducers use “game changing” traction drive technology. The MAR-17-1-3.1 and the MAR-23-1-3.1 Speed Reducers feature 98% efficiency and with only 6 moving parts they typically out last conventional gearboxes and speed reducers by a factor of 3. The MAR17-1-3.1 Speed Reducer is designed for input speeds up to 3600 rpm with 10 to 20 in/lbs of torque, and the MAR-23-1-3.1 Speed Reducer is also rated for speeds to 3600 rpm but with an input of 20 to 30 in/lbs of torque. As the output speed is reduced by a factor of 3 the output torque increases by a factor of 3.

Using an engineered traction fluid with a coefficient of friction of just 0.1 to 0.12 that cools and lubricates the traction drive these high efficiency speed reducers generate up to 72% less heat even after days of continuous operation. There is no slippage or lost motion between the input and output shafts even though there is no metal to metal contact as the traction fluid is continuously changing from liquid-to-solid-to-liquid as the driving and driven elements interface in the drive. Creating 38% lower dB at 3000 rpm than conventional gearboxes these people friendly speed reducers are ideal for use in medical equipment such as mobile hospital equipment and dialysis machines as well as pumps, blowers, fans, turbo and super chargers, conveyers, HVAC systems, and other power transmission and motion applications.

Having low vibration, and no torque losses from 10 to 3000 rpm, these speed reducers featuring traction drive technology lets a motor operate at peak efficiency while having a damping effect on a motor’s torque ripple. These revolutionary speed reducers are available with an optional overriding clutch. Incorporating standard NEMA mounting dimensions, these speed reducers can be easily integrated into new and existing applications.

About Rolling Motion Industries (RMI)-

About Rolling Motion Industries (RMI): In 1993 John Pawloski and his brother Ray took over the family business, Jewelers Machinist Co. They realized they needed to switch from outdated conventional thread grinders to CNC thread grinders. As a result, Jewelers Machinist Co is recognized as the source of some of the most complex thread grinding in the industry. The concept for the RMI traction drive came from John in 2007. Working in that high precision industry aided John in the development of the RMI Traction Drive.

In the years that followed, the design of the individual components and formula of the engineered traction fluid were finalized, testing was completed, a patent granted, and production begun. The RMI Traction Drive is one of the most efficient ways to transmit power from one point to another. Utilizing rolling motion, RMI is able to transfer power at various ratios with minimal energy loss. Tested against V-belt, direct drive, chain, and gearbox setups, RMI Traction Drives offer energy saving benefits through true efficiency rating percentages up to 98%. The high efficiency of the traction drive allows electric motors to run at their peak efficiency ranges.

There are many applications where it can be used from automotive to industrial to medical. The RMI traction drive can be used in the electric vehicle market and precision applications. Offering benefits such as low backlash and no back driving, it set a new standard for “high efficiency”.

Motion Control – Linear Servo Controller Amplifier to Control Voice Coil Motors

motion control servo controller

Forestville, CA,   —  Motion Control – The SCA814 Linear Servo Controller was specifically designed to control single phase, non-commutated devices like voice coil motors.  like it’s field proven predecessor the SCA754 is a high performance single axis DC motor controller and amplifier system.  It is comprised of a highly integrated single PC board level product with a cohesive interface.  This card provides current amplification and analog servo control interfaces.  The single-phase characteristic of the current amplifier makes it particularly well suited for DC motors such as galvanometers and voice coils.  It was specifically developed for control of motor applications requiring both high temporal and spatial servo precision, such as machine vision, inspection, scientific imaging, medical imaging and other business applications.  This amplifier interfaces directly to many of the Equipment Solution motor/stage solutions.
Besides galvanometers the SCA814 is directly compatible with all the ESI linear voice coil stages and the optical scanners.  A bipolar linear or switching regulated power supply is required by the SCA814 amplifier.  Typically better performance can be achieved when using a linear power supply.  Equipment Solutions has several high-current supplies for this purpose including the SPS15 ±15V DC Switching Power Supply .

The New Sales Funnel – Adapting to Change

Motion Control Marketing – Adapting to the New Marketing Paradigm

A message for Motion Control Marketers

The role marketing is expanding!

As a marketer of technical products I make an effort to view the sales process as a consumer.  Fact – All consumers are not alike.  Speaking only for myself, although, I believe there are many like me, that want to do their own research, and ONLY talk to sales when they are ready to.

Depending on the consumer it may be early or late in the sales process.  Perhaps the sales funnel should reflect an overlap rather than have a line at which the process switches from marketing to sales.  That said, consumers need to be aware of a product, have their interest aroused, have cause to consider the product, and have an interest in purchasing the product.  Marketing today necessarily has a bigger role in the sales process than in years past.

Years ago (pre-internet) a potential customer saw a product release or an ad in a magazine, circled a number on a “Bingo Card” and got a sales call made on him.  Today the potential customer sees a product release or ad and starts to do his own research.  In addition to some reviews, he will find data sheets, application notes, videos, dedicated web pages, and blogs online (products of the marketing department) all of which will be carefully reviewed before a sales person is ever called.

Developing and implementing an effective Business-to-Business marketing program for technical products that:

Creates Awareness of …

Generates Interest in …

Causes Consideration of …

Raises the level of Intent to …

and

Aids in the Evaluation of …

Does not have to be expensive! 

However, It does have to be well planned …       … and that plan has to be carried out.

For large companies the marketing program can include: Paid Advertising, Product Releases, an expensive interactive Website, a Blog, Data Sheets and Brochures.  All effective tools to create Awareness, Interest, Consideration, etc.

For smaller companies an effective reasonably priced, affordable marketing program can include: Product Releases, a Website, perhaps a Blog, and Data Sheets.

Product Releases are great for creating Awareness of, they also generate Interest in, and cause further Consideration of your products, each time the release is seen in a different print or online publication.

The Website does not have to have an expensively developed “WOW” factor as much as it has to have the information needed to determine if your product is right for the prospects application, or if you have the capability of supplying a custom product to meet or perhaps even exceed his or her needs.

A simple inexpensive blog, can also be an effective marketing tool.

Data Sheets …   … Create a straight forward format for an online data sheet that provides the technical data needed helps in the Evaluation that then can lead to the Sale!

 For over 30 years I have been marketing exclusively Motion Control products. First as a Marketing Manager and then as Marketing Consultant.  I have enjoyed working with several companies for over 20 years.  Email me at dwtechcom@gmail.com and see how inexpensive an effective marketing program can be.
