Yes, in theory all motors or generators can be inverted into generators or motors. There is no need to remove the squirrel cage when converting an asynchronous motor to a generator. Simply connect and add a DC motor as shown. in the figure below. Capacitors with resistance voltage greater than 450V. The wiring method is to connect the asynchronous motor in a Y shape, connect the three sets of capacitors in a Δ shape, and then connect them in parallel. When the main motor drives the asynchronous motor to reach a certain speed, the output voltage of 380V can be obtained at any two points of Ll, L2 and L3. If you need 220 V, you can take the voltage between any phase and point 0 on Ll, L2 and L3 to get 220 V.
Motor power and value of corresponding capacity:
