AN2372 Application note
the stator currents the rotor that is already locked with the stator flux also changes its orientation to take the new position of the stator flux. If the stator is now excited with sinusoidal varying currents the stator flux inside the motor spins at the frequency of its sinusoidal currents and pulls along the rotor at this frequency.

Dec 10 2020 These motors are also used on large pumps in the water and waste industry. A WRIM has a 3 phase wound stator that is usually connected directly to the power system. The rotor has a 3 phase winding with the three terminals connected to separate slip rings which were traditionally connected to a rheostat or resistor bank.
The new EQE electric drive
The magnets are arranged inside the rotors in an NVH optimised way known as sheet metal cut . This also reduces the use of rare earths. The shape of the winding what is known as the stator tilt also supports vibration comfort especially at low speeds. In relation to the permanent magnets of the rotor the coils of the stator are obliquely
