The motor from the washing machine, or the universal serial motor, is one of the most used motors. Almost everyone has it in the washing machine at home. Even though more modern engines are coming in recently. The motor from the washing machine has an input of approx. 400 W and can spin over 10,000 revolutions per minute. Universal series motor works on both AC and DC. It is in series because the stator and rotor windings are connected in series. I've seen a few different terminal block connections, so it seems safest to figure out which wires go to the stator and which to the rotor, and simply connect the two windings in series. When idling without a mechanical load, the engine reaches significant revolutions, it is said that there is a risk of engine damage. Also for this reason, it is advisable to use a regulator. Either a simple one from a vacuum cleaner or a more complex one from a Chinese store with a display and precise speed control. (affiliate link) https://s.click.aliexpress.com/e/_AXRzKN
