What is a Servo Motor?

A servo motor allows precise control of position, speed, and torque. Servo motors come in rotary and linear types. KOMOTEK designs and manufactures rotary servo motors.
For precise control, servo motors use feedback devices such as Hall sensors, encoders, and resolvers.
The servo drive receives a position, speed, or torque command from a higher-level controller. It reads signals from the motor’s feedback device and uses its control algorithms to calculate the output needed to follow the command. The drive’s inverter then uses pulse-width modulation (PWM) to regulate the voltage and current supplied to the motor.
