Brushless
- Brushless DC servo motor offers high efficiency and low maintenance by eliminating brushes, reducing wear.
- Precise control and better high-speed performance due to electronic commutation.
- Longer lifespan and higher reliability because there are no brushes to wear out.
Brushed
- Brushed DC Servo Motor has lower efficiency and higher maintenance due to brushes causing friction and wear.
- Simpler control but less effective at high speeds due to mechanical commutation.
- Shorter lifespan and lower reliability due to brush wear.

By Control Methods
DC servo motors are commonly controlled through various methods to achieve precise speed, position, and torque control.
Armature Voltage Control
- The armature controlled DC servo motor's speed and position are regulated by varying armature voltage, ensuring good speed control and simple implementation.
Field Current Control
- In a field control DC servo motor, varying the current in the field winding adjusts magnetic field strength and motor speed, allowing fine-tuning of speed and torque.
PID Control
- Closed-loop method using feedback, the PID controller minimizes error between desired setpoint and actual position or speed by adjusting control inputs.
PWM Control
- Involves rapidly switching the motor's power to control average voltage and current, providing high efficiency, good dynamic response, and precise control.
Position Control
- Uses position feedback devices like encoders to control the motor accurately, ensuring high precision and repeatability in positioning tasks.
Current Control
- Regulates torque by controlling current, often with other methods, providing direct control for smooth and accurate motor performance.

FAQ
What is a DC synchronous motor?
A DC synchronous motor is a kind of electric motor in which the supply current frequency and the shaft rotation are synced. This means the motor's rotor turns at the same speed as the current’s oscillations.
What is the role of an encoder in a brushless DC servo motor?
An encoder provides feedback on the motor’s position, speed, and direction, allowing the controller to make precise adjustments to achieve the desired performance.
Can a DC servo motor operate at varying speeds?
Yes, a DC servo motor can operate at varying speeds. The controller has two options: it can adjust the input voltage or modify the speed using pulse-width modulation (PWM).
What types of feedback devices are commonly used with DC servo motors?
Encoders and resolvers are common feedback devices that give the control system precise position and speed feedback.
