Speed-varying methods of motor:
There are many motor speed control method, which can adapt
velocity changes requires of different changes in different
The output power will change with the rotational speed with the
regulation of motor speed.
From the perspective of energy consumption, speed can be roughly
divided into two kinds:
1. The input power holding steadiness.
2. Control the motor input power, adjust the speed of the motor.
