Direct drive rotary motors (DDR) are motors that are designed to drive loads directly without the need of any transmission mechanism , such as gear or belts. These motors are also called torque motors. They use high energy permanent magnets to generate high torque . Akribis offers various types of DDRs, including AFR-A series , ADR-P , ADR-T series and ACD series. We also design customized direct drive motors according to spec. All Akribis direct drive rotary motors are equipped with optical encoders. With higher encoder resolution after interpolation, Akribis rotary motors can satisfy your need of precision in any type of demanding applications
Voice coil motors are short stroke actuators that use permanent magnets and coil windings to generate thrust force. It is a direct drive motor, which means that the motor drives the load directly without the need of a transmission mechanism . Akribis offers various types of voice coil motors, including AVM series cylindrical motors series and ATA series planar motors. Advantages of using voice coil actuators are low moving mass , low inductance , smooth motion and superb reliability. Voice coil motor perfectly fit to force control applications . The force produced by a motor is linearly proportional to the current applied.
