KNOWLEDGE BASE --- Brushless DC Servo Motor

There are two main control methods for DC servo motors. One is armature voltage control, namely, when the stator magnetic field remains unchanged, the speed and output torque of the motor are controlled by controlling the voltage signal applied to the armature winding end. The other is excitation field control, that is, by changing the magnitude of the excitation current to change the strength of the stator's magnetic field so as to control the speed and output torque of the motor.

When the armature voltage control method is adopted, because the stator magnetic field remains unchanged, the armature current can reach the rated value and the corresponding output torque can also reach the rated value. As a result, this control method is the most convenient to realize. If the motor is driven by the actuator with a constant torque load, the armature current will not change before and after the speed adjustment. When the excitation field control method is adopted, since the magnetic field of the motor is close to saturation under the rated operating conditions, the speed of the motor can only be changed by weakening the magnetic field. Since the armature current is not allowed to exceed the rated value, the magnetic field weakens, the motor speed increases, but the output torque decreases and the output power remains the same. Therefore, such a method is also called constant power speed regulation.

The permanent magnet DC servo motor is usually used in the mechatronic servo system, so the armature voltage control method with the constant torque speed regulation is used , which is also consistent with the load characteristics required by the servo system.

The DC servo motor has features of rapid response, high precision and efficiency, wide speed range, large load capacity and output power and excellent control.

With the development of electronic technology, a new type of DC servo motor using electronic devices for commutation has appeared. It replaced the brushes and commutators of the traditional DC servo motor, so such a servo motor is called a brushless DC servo motor, which has high performance, longer service life because its commutator and brush parts have been replaced.
