How many throttle coils does the motor have?

Look at the number of motor poles. A 2-pole motor has 2 sets of windings in each phase. Three phases are six sets. Each winding group has single winding, double winding or multi-winding, as long as it depends on the motor power.

A 4-pole motor with rated number of slots has 4 windings per phase, and so on. When winding together, they are wound separately, and they don't need to be connected when winding.

When winding, it is wound separately, and it should be connected after winding.
