MOTORS

A stepper motor is a type of electric motor in which rotation is achieved in discrete steps. A stepper motor can provide very precise movement, in the best case even in increments as small as half a degree, without position feedback from the shaft. Stepper motors require a separate drive/control circuit. They are typically used in applications where accurate positioning is required.

A servo motor usually includes a pulse-type sensor integrated into the same unit as the motor, to measure the shaft angle and count revolutions. A servo motor is controlled by an electronic servo drive, which receives the actual position feedback from the motor and compares it with the desired position. Based on this information, the servo drive controls the motor movement.

Servo motors are available in several types, including DC servo motors, brushless DC servo motors, and AC servo motors. Servo motors are used in many precision-demanding applications such as the axes of CNC machine tools, automotive power steering and cruise control systems, aircraft fly-by-wire control systems, and radio-controlled equipment.

KLINGER Finland supplies stepper and servo motors from several different manufacturers and helps select the most suitable solution for each application.
