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 .
