How to adjust the speed of DC motor?

A DC motor is a rotating device that has the ability to transform mechanical energy into DC electrical energy or vice versa. The motor's speed must occasionally be changed in order to satisfy consumers' actual product needs. What are the micro DC motors' methods for adjusting speed then? Here is a succinct overview of Vshida Micromotor.

1. To regulate speed, adjust the armature circuit resistance

By altering the armature circuit's resistance, any type of DC motor can be made to work more efficiently. When the load is constant, the total resistance of the armature circuit increases as the external resistance linked in series increases, and the motor speed drops.By toggling the contactor or the master switch, the external resistance can be changed.

2. Modify the speed management of the armature voltage

The DC motor may provide stepless speed regulation over a large range by continuously varying the armature supply voltage. There are two ways to modify the armature supply voltage: a generator-motor unit-powered speed control system and a thyristor converter-powered speed control system.

3. Adjust the current speed regulation for excitation

Changing the excitation current of the DC motor can also regulate speed when the armature voltage is constant.

These three straightforward techniques can control the speed of small DC motors. Continue to pay attention to us for further details.
