Sergei asks:
Please tell me how to properly connect a collector motor like this. I do not know direct or alternating current. The scheme is like this:

The answer to the question:
Your circuit doesn’t explain much. Tell me where did the electric motor get stuck, where did it work before, what identification marks are there on it? It looks like this is a mixed-excitation engine, then the voltage is applied in pairs to the blue and red (according to your scheme) wires, but it is not a fact that the full voltage is applied in this way. A serial connection is also possible, for example, 2 and 3 wires, and 220V should be supplied to 1 and 4. And generally it is not known whether it is 220V or not. Waiting for details!
