KNOWLEDGE BASE --- DC Servo Motor Speed Control Method

According to the speed formula of the DC servo motor, there are three basic speed adjustment methods of the DC motor, namely, adjusting the resistance R, adjusting the armature voltage U and adjusting the value of the magnetic flux Φ. But the speed regulation of armature resistance is not economical and the speed regulation range is limited. Therefore, it is rarely used.

1. When adjusting the armature voltage, if the armature current I is kept constant, the magnetic field flux Φ remains unchanged. It can be seen that the electromagnetic torque T of the motor remains unchanged and is a constant value. Therefore, the voltage regulation and speed regulation are also called speed ​​regulation for constant torque.

2. When adjusting the magnetic and speed, the armature voltage U is usually kept at the rated voltage. Since the current in the excitation circuit can not exceed the rated value, the excitation current is always adjusted to a decreasing trend, which reduces the magnetic flux. It is called field weakening. At this time, the torque T also decreases, while the rotation speed increases. During the speed regulation process, the armature voltage U remains unchanged and if the armature current I remains unchanged, the output power remains the same. Therefore, the magnet and speed regulation are also called speed regulation with constant power.

The figure shows the mechanical characteristic curve of the DC motor in adjusting the armature voltage and adjusting the magnetic flux for speed regulation mode. In the figure, nN is the rated torque, TN is the rated speed, and △nN is the rated speed difference. It can be seen from the figure that when the armature voltage is adjusted, the mechanical characteristics of the DC motor are a set of parallel lines, that is, the slope of the mechanical characteristic curve remains unchanged, but only the ideal speed of the motor is changed, maintaining the original mechanical features. Therefore, the speed control of the servo feed system of the CNC machine tool adopts the speed control method of adjusting the armature voltage. The mechanical characteristics of permanent magnet DC servo motors just meet this speed regulation requirement. Therefore, the feed system of CNC machine tools often uses permanent magnet DC motors.

It can be seen from the figure that the magnetic and speed regulation not only changes the ideal speed of the motor, but also softens the mechanical characteristics of the DC motor. Therefore, the magnetic and speed regulation is mainly used for the speed regulation of the spindle motor of the machine tool.
