The industrial dc servo motor is a microspecial motor used as an actuator in an automatic control device. Its function is to convert the angular displacement or angular speed of an electrical signal into a rotating shaft. The industrial dc servo motor also known as an executive motor, is used as an actuator element in the automatic control system to convert the received electrical signal into an angular displacement or angular speed output on the motor shaft.
The industrial dc servo motor has the advantages of good low voltage characteristics, strong torque overload characteristics, large starting torque (rotation blocking characteristics), and small starting current.
Brushless DC moment motor (brushless direct drive motor) is widely used in robotics, automobiles, tools, industrial control, automation, aerospace and other fields.
