This board is a Pulse Width Modulation (PWM) DC motor speed controller. It converts AC input (typically 220V or 110V depending on the specific sub-model) into a variable DC output to drive the lathe’s permanent magnet motor. Regulates the RPM of the spindle motor.

: Supplies the rectified DC voltage to the motor brushes. jymc220bi schematic full

: 0–90V DC (for 110V units) or 0–180V DC (for 220V units). Current Rating : Typically 12A to 13.5A DC. This board is a Pulse Width Modulation (PWM)

: Mounted on the heat sink to handle the high-current motor load. jymc220bi schematic full
