When it comes to precise and reliable motion control, brushed DC servo motors are a popular choice These motors offer a wide range of benefits that make them suitable for various applications, including robotics, automation, and CNC machines In this article, we will explore the working principle, advantages, and applications of brushed DC servo motors.
Working Principle of Brushed DC Servo Motors
A brushed DC servo motor consists of a stator (stationary part) and a rotor (rotating part) Inside the motor, there are permanent magnets attached to the rotor and electromagnets on the stator The rotor is connected to a shaft that spins when a current is applied to the electromagnets on the stator.
The key component of a brushed DC servo motor is the commutator, which is a rotating switch that changes the direction of the current in the electromagnets to keep the rotor spinning in the desired direction Brushes are used to maintain contact with the commutator and transfer electrical power to the motor.
