motion control - linear actuator


motion control - moticintThe SDLM-019-070-01-01 direct drive linear motor has a stroke length of 0.500 in. (12.7 mm) and a continuous force rating of 7.3 oz. (2.0 N) and peak force of 23.0 oz (6.4 N).  This non-commutated direct drive servo motor features: Quiet long life, plain linear bearings, an integrated internal 1.25 micron resolution (0.000049 in.) quadrature optical encoder with differential outputs, and a non-rotating shaft.  Applications include: Manufacturing (assembly and inspection equipment), sorting and packaging, semiconductor handling, medical procedure tables and instruments, antenna positioning, dampers, door & valve actuators, agricultural equipment, shaking, and adjustable office furniture.Van Nuys, CA – Motion Control Products – The new patented SDLM-019-070-01-01 direct drive linear motor with integrated position and temperature sensors is the latest addition to the series of zero backlash, zero cogging, high acceleration, high speed, high resolution, long life motors from Moticont. Also known as an electric cylinder, this compact direct drive linear motor is just 0.75 in. (19.1 mm) in diameter and 2.75 in (69.9 mm) long.  Protected inside the motor housing, the linear optical quadrature encoder is directly connected to the shaft for the greatest possible accuracy. Highest throughputs are achieved by the SDLM-019-070-01-01 linear motor when operating at peak efficiency monitoring the data from the internal temperature sensor.

Direct coupling of the load or stage to the low inertia non-rotating shaft eliminates backlash and allows for high acceleration/deceleration.  Both ends of the actuator and shaft ends have threaded mounting holes for easy integration into new and existing applications. The SDLM-019-070-01-01 Direct Drive Linear Actuator is also available with a matching servo controller

Motion Control – Long Travel and High Torque Rotary Voice Coil Actuators from H2W Technologies!

Motion Control – High Torque Rotary Voice Coil Actuators

motion control rotary voice coil actuator

H2W Logo

Santa Clarita, CA — Motion Control – H2W Technologies has developed several high torque rotary voice coil actuators, otherwise known as a limited angle torque motors or LATs. The model TWR-034-800-1RC was designed to allow for a relatively low moving mass and inertia, as well as a long rotary stroke of 34 degrees [0.59 radians] on a 11.4” [290 mm] arm, which equates to a travel of 6.75 inches [171.5 mm] which is long travel for this style of actuator, which typically restrained to an equivalent linear travel of 2 inches [50.8 mm]. This rotary voice coil actuator can generate a continuous torque of 1400 in-oz [9.8 N-m] and a peak torque of 4200 in-oz [29 N-m] at a duty cycle of 10% (i.e. 1 second on, and 9 seconds off) in each coil on a 11.4 inch [290 mm] rotation arm.  The TWR-034-800-1RC has a total angular displacement of  34 degrees [0.59 radians] and a motor constant of 275 in-oz/sqrt(watt) [1.92 N-m/sqrt(watt)].

The Voice coil motor requires 1.7 amps of continuous current per coil and 5.1 amps of peak current per coil to generate the specified forces.  The actuator fits in and envelope of 10.26 in [260.5 mm] x 3.01 in[76.4 mm] x 3.39 in [86 mm].  The moving coil design ensures a hysteresis free movement as the coil is wet wound and self-supported, and the non-commutated coil allows for ripple-free motion and no cogging.  The voice coil actuator has been designed with mounting provisions in the magnet and coil assemblies.  This allows for the integration of a bearing system to maintain the clearances between the coil and permanent magnetic field assemblies. The rotary voice coil actuator is ideal for applications requiring high torque and high- speed applications. Examples of such applications are driving a gimbal axis in scanning applications as well as providing stabilizing torques for image stabilization. More examples of H2W’s Rotary Voice Coils are available on our website: https://www.h2wtech.com/category/rotary-voicecoil-actuators

Motion Control Voice Coil Actuators Used in Ventilators Available in 4 Weeks from Receipt of Order!

Motion Control – Voice Coil Actuators Used in Ventilators 

To help deal with the COVID-19 pandemic these actuators are available in OEM quantities in 6 to 8 weeks from receipt of order!

motion control Actuator for Medical Ventilators

motion control company -H2W Technologies

When three-phase AC power is applied to the primary, a travelling electromagnetic flux wave is induced and moves relative to the primary. The wave induces an electric current in the conductive reaction plate. The induced electric current interacts with the magnetic flux to produce a linear force. The speed of the motor can be varied by changing the input frequency using an adjustable frequency drive.

 

The actuator utilizes a unique electromagnetic circuit design. This design allows for a motors with minimal cross section diameter of up to 1.20 inches [30.5 mm], and strokes up to 0.60 in. [15.2 mm] stroke; this size generates up to 1.12 lbs [5.0 N] of continuous force and 3.36 lbs [15 N] of peak force.  Each actuator is guided by sliding contact bushing assemblies. Voice coil actuators are ideal for applications that require quick, short moves with fast settling times.

 

Features

  • – High Speed
  • – Low-profile
  • – Long bearing life in a high cycle environment
  • – No moving cables
  • – High acceleration
  • – Compact footprint
  • – Custom strokes and force configurations available

Motion Control – Redundant Coil Voice Coil Motor Available from H2W Technologies, Inc!

Motion Control – Redundant Voice Coil Motor!
motion control - redundant voice coil motor

 

Motion Control - H2W Logo

Santa Clarita, CA —–

When three-phase AC power is applied to the primary, a travelling electromagnetic flux wave is induced and moves relative to the primary. The wave induces an electric current in the conductive reaction plate. The induced electric current interacts with the magnetic flux to produce a linear force. The speed of the motor can be varied by changing the input frequency using an adjustable frequency drive.

Each coil pair operates as its own voice coil.

Redundancy is a requirement on many flight systems in a special case when one coil faults, the other can be used to make the motor “fault-resistant”.

Other systems require simplified circuitry which would not allow the change of current polarity in order to change the direction, in these cases each coil can be used to drive the coil in a single direction. The challenge in manufacturing a redundant coil is ensuring the same performance no matter the coil, which requires precise manipulation of the magnetic circuit design, and the precise coil layout to ensure the identical operation and constants for each coil. This will allow the controls to seamlessly switch between the two coils.

There are two ways of accomplishing this coil redundancy. The most common way would be to generate multiple coils operating on individual magnetic circuits. This requires a longer coil and multiple magnetic circuits; however this is the most robust design and the least vulnerable to damage or interference from the redundant coil. The NCC08-18-025-2R2C is an example of the multiple coil design. An alternate method, which allows for the most compact solution, would be a multi-filar wind. This method only requires one magnetic circuit, which is why the length is shorter. In this case multiple coils are wound in the same winding space.
