How to connect a 380 volt motor to a 220 volt motor?

The wiring from 380v motor to 220v motor is shown in the above figure.

Extended data

Voltage, also called potential difference or potential difference, is a physical quantity to measure the energy difference of unit charge in electrostatic field due to different potentials.

Its magnitude is equal to the work done by the unit positive charge moving from point A to point B under the action of electric field force, and the direction of voltage is defined as the direction from high potential to low potential.

The international unit system of voltage is volts (V for short), and commonly used units are millivolts (mV), microvolts (μV) and kilovolts (kV). This concept is similar to the "water pressure" caused by the high and low water level.

It should be pointed out that the word "voltage" is generally only used for circuits, while "potential difference" and "potential difference" are generally used for all electrical phenomena.

In order to make the motor rotate, the control department must determine the sequence of turning on (or turning off) the power transistors in the inverter according to the position of the motor rotor sensed by the Hall sensor and the stator winding.

The current flows through the motor coil in turn, generating a forward (or reverse) rotating magnetic field, which interacts with the magnet of the rotor to make the motor rotate clockwise/counterclockwise. When the motor rotor rotates to the position where the Hall sensor senses another set of signals,

The control part turns on the next group of power transistors again, so that the circulating motor continues to rotate in the same direction until the control part decides to stop the motor rotor, and then turns off the power transistors (or only turns on the lower arm power transistors);

If the motor rotor is reversed, the turn-on sequence of power transistors will also be reversed.
