VOICE COIL ACTUATOR VOICE COIL ACTUATOR MMB Series MMB Series The designs of the Moving Magnet Voice Coil Actuators have been proven in various high-end industrial equipment. These actuators can be applied frequently where high speed, high force density and a high reliability/lifetime are required. The integrated bearing system allows for a low cost high reliability design that is easy to integrate into your application. The working principle of these moving magnet voice coil actuators is that the moving part is a magnet. The coils are attached to the static part of the actuator which enables a good thermal path. A good thermal path is beneficial for high force densities. The absence of moving wires leads to very high reliability and lifetime and does not limit the achievable accelerations and speeds.

VOICE COIL ACTUATOR MOTOR CONTROLLER MMB Series Single phase 2-wire VCA Drive Magnetic Innovations’ Moving Magnet VCA series are matched with a dedicated motor controller which is able to establish sensorless position control (no external encoder required). Hence only 2 wires are required to power and position control the actuator. The controller is an encoder and drive in one package at the size of a matchbox which can power Moving Magnet VCA’s up to 1kW. Customers are able to program their required motion patterns into the motor controller utilizing a HMI running on a PC. After...
