DC SERVO MOTORS A servomotor is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity and acceleration.It consists of a suitable motor coupled to a sensor for position feedback. It also requires a relatively sophisticated controller, often a dedicated module designed specifically for use with servomotors.

Servomotors are not a specific class of motor although the term servomotor is often used to refer to a motor suitable for use in a closed-loop control system.

Servomotors are used in applications such as robotics, CNC machinery or automated manufacturing.

DC SERVO MOTORSThere are various types of dc servomotors which are:

Permanent magnet shunt motorSplit series motor

PERMANENT MAGNET SHUNT MOTOR Permanent magnet shunt motor is a fixed excitation motor where the field is actually supplied by a permanent magnet. Performance is similar to armature controlled fixed field motor.

SPLIT SERIES MOTORS Split series motor are the dc series motor with split-field rated with some fractional kilowatt . This type of motor can operate as a separately excited field-controlled motor. The armature is supplied with a constant current source. Split series motor has a typical torque-speed curve . This curve denotes high stall torque and a rapid reduction in torque with increase in speed. This results in good damping.
