Washing machine

Washing machine is a cleaning appliance that uses electrical energy to generate mechanical effect to wash clothes. According to the driving method, there are direct drive, belt drive, and pulsator drive.

Based on MindMotion’s MM32SPIN0280 microcontrollers, the washing machine, in which the main control board can directly control the BLDC, takes MM32SPIN0280 as the main control.
