winding data

[andriibol]

the motor was rewound according to the stator winding diagram. In theory, this scheme should be good, but when the motor is turned on for a short time, it takes very large currents on the delta-connected and also when the star-connected, the motor heats up a lot. Probably the whole problem is in the circuit according to which the motor was wound, so what could be wrong with this circuit?

One or more winding groups connected backwards.
Remove the rotor.
Apply a small DC current through each winding in turn.
Explore the stator with a compass.

Recommendation:
When inquiring about a specific electric motor, always provide a photograph of the motor nameplate to ensure an accurate response.
The attached diagram is marked as a2 and drawn somewhat like a4.
In fact, the diagram is incorrect for both a2 and a4.
The first thing you need to clarify is whether you need a diagram fora2 or a4. This mainly depends on the motor power .

In theory, this scheme should be good,

No, is not good.
Sometimes, with large LV (Low Voltage) motors, the 2-pole winding has very few turns or the number of t/c (turns per coil) is small, even decimal, so it is necessary to use a3 or a4 but not in this way. Two-pole a4 is not so obvious, but more complex.
