    Please help. The capacitor is CBB61 4uF. I am sending a picture with R measurements

    Capacitor between white and red, red and black under 230V.

    I don't want to start a new topic because I have a similar problem. Three wires from the motor (red, green and yellow) but there are approximately 203 ohms in between each. The engine ran until the end of the typewriter. How to connect it? 4uF capacitor.

    @ grzegorz.bk If the winding resistance is equal, it means that it is a reversing motor. So if you connect a capacitor, you will get either right or left turns.

    So I can choose any two wires to which I will give voltage from the socket? And then to one of them and to the third (free) connect the capacitor. I understood?

    @ grzegorz.bk Yes. This motor has winding connections in a triangle, hence the measurement result.

    I have such a capacitor. May be?

    Can not! because the voltage on it will be around 300 VAC. On the first photo you have the right one.

    Thank you very much for your help. In that case I will buy the right one and go back to testing. Regards.

    It worked. I got the original capacitor that worked with this engine in a typewriter. :)

    Hello, the device works on? Does anyone have information where this engine can be bought?

    Hello.
    How can we test if this motor is working?
    ( Can we Just plug in 230V between red and white inputs?)
    It needs the capacitor for what?

    Thanks in advance
