The voltage regulation mode of single-phase series motor adopts controllable phase-shifting voltage regulation, and the trigger voltage of SCR lags behind the input voltage, thus realizing the phase-shifting trigger of the input voltage. There are two ways to realize it: hardware and software.

In order to obtain reliable motor speed control in hardware design, an ASIC is used as the control circuit, and a speed sensor is installed on the motor shaft to feed back the speed signal, so that the set speed of the motor remains stable and does not change with the load.

Precautions:

1. Clean the dust and oil stain on the motor housing in time and check whether the terminals are in good contact.

2. Check whether the transmission device is broken or damaged, and whether the installation is firm.

3. Check and clean the motor bearing regularly and change the lubricating oil.

4, often check the insulation resistance of the motor, regularly check whether the chassis grounding is reliable.

5, regularly clean the brush and steering gear surface, check whether the brush and steering gear are in good contact.
