Servo Motors

Servo motors are at the heart of modern automation and drive technology. Whether in machine tools, robotics, packaging machinery, conveyor systems, or semiconductor manufacturing, servo drives are used wherever precise positioning, high dynamics, and accurate motion control are required.

The performance of a servo system depends not only on the motor and controller but also on the mechanical transmission components. Miki Pulley shaft couplings, electromagnetic brakes, spring-actuated safety brakes, and torque limiters ensure precise power transmission, maximum positioning accuracy, and the highest level of operational reliability in demanding servo applications.
