Quali sono i metodi più comuni di regolazione della velocità per i motoriduttori in corrente continua? Come sono le caratteristiche

DC geared motors, or geared motors, are based on a common DC motor plus a matching gearbox. The function of the gearbox is to provide a lower speed and a higher torque. DC geared motors are widely used in the steel industry, machinery industry, etc. The advantages of using DC geared motors are simplified design and space saving, so what are the speed regulation methods of DC geared motors? What are the characteristics?

1. Adjust the speed above the base by weak magnetic regulation. In general DC motors, the magnetic field can only be weakened, not enhanced, to avoid oversaturation of the magnetic circuit. When the armature voltage keeps the rated value, the series resistance of armature circuit gradually decreases, which makes the resistance of excitation circuit Rf increase, the excitation current and flux decrease, the motor speed increases immediately and the mechanical characteristics become soft.

2. Reduce the armature voltage to regulate the speed. The armature circuit must have adjustable voltage DC power supply, and the resistance of armature circuit and excitation circuit should be as small as possible, the voltage will be reduced, the speed will be reduced, the running speed will be stable, and the infinitely variable speed regulation can be realized.

3. Armature circuit series resistance speed regulation. The larger the series resistance, the softer the mechanical characteristics, the more unstable the speed, the higher the series resistance at low speeds, the greater the energy loss, the lower the efficiency. The speed control range is affected by the load size. When the load is large, the speed control range is wide; when the load is light, the speed control range is small.

These are the common speed control methods and characteristics of DC geared motors, master these basic speed control methods, in order to better use the geared motor, in order to bring more convenience to production life!
