What Are The Three Main Components Inside A DC Servo Motor?

In fields such as special robots, aerial work platforms, and AGVs, DC servo motors, as core drive components, their performance directly affects the stability and efficiency of equipment operation. A DC servo motor is composed of components such as keyways, front flanges, rotors, stator, rear flanges, brakes, encoders.

• Stator

The stator is composed of an iron core and windings, and its magnetic pole magnetic field is generated by the magnetic poles of the stator. According to the way of generating magnetic fields, DC servo motors can be classified into permanent magnet type and separately excited type. Permanent magnetic poles are made of permanent magnetic materials, while separately excited magnetic poles are formed by laminating stamped silicon steel sheets. When powered on, the windings in the stator generate an electric field, causing current to flow through the stator. Due to the force between the stator and the magnets on the armature poles, the armature will start to rotate. The rotation direction of the motor can be controlled by changing the direction of the current in the winding.

• Rotor

The rotor, also known as the armature, has an iron core made of silicon steel sheets stacked together, with coils embedded on its surface. When the armature current passes through, it generates an electromagnetic torque that drives the load to rotate under the action of the stator magnetic field. Rotor bearings are components that support the rotor, ensuring its stability and rotational freedom.
