Frameless Motors and Torque Motor Kits – MSK & MQ

Our frameless motors offer excellent torque density, precision and efficiency in a particularly compact package. Our frameless motors are ideal for rotary drives, submersible drive systems, flight control actuators, sensor gimbals, robot and cobot joints, or any other application requiring maximum precision, performance and reliability in a compact application design.

MSK Series

Synchronous Servo Motors for Compact Applications

Our MSK synchronous servo motors are three-phase, permanent magnet and brushless motors in kit form. They have been specially developed for demanding servo applications in industrial and automation technology as well as for applications with limited installation space.

MQ Series

Torque Motor Kits for High Torque

The MQ Series includes powerful torque motors in kit design. It is available in seven sizes, each offering five different versions for different performance and application requirements.

MSK Series

Servo Motor Kit for Compact Installation Spaces
