This equipment includes a stator, rotor core, motor shaft, servo motor winding commutator, servo motor windings, tachometer windings, and tachometer commutator. The rotor core is constructed by stacking and fixing silicon steel laminations onto the motor shaft.
DC servo motors are divided into brushed and brushless motors. Brushed DC servo motors-low cost, simple structure, high starting torque, wide speed range, easy control, require maintenance but are convenient (carbon brush replacement), generate electromagnetic interference, and have environmental requirements. Therefore, they can be used in cost-sensitive general industrial and civilian applications.
Brushless DC servo motors-small size, light weight, high output, fast response, high speed, low inertia, smooth rotation, and stable torque. They are easy to intelligentize, and their electronic commutation method is flexible, allowing for square wave or sine wave commutation. The motor is maintenance-free, eliminating carbon brush wear, and boasts high efficiency, low operating temperature, low noise, minimal electromagnetic radiation, long lifespan, and suitability for various environments.
