  • Electromotor having integrated inverter
    Patent number: 11689084
    Abstract: An electric motor has a stator and a rotor for rotation relative to the stator. The stator has a plurality of stator windings distributed along the circumference of the stator. Each stator winding is connected to a respective end terminal. Driver circuitry is coupled to the plurality of stator windings for creating a rotating magnetic field for driving the rotor. The driver circuitry has one driver module per stator winding. Each driver module is mounted close to its respective stator winding. Each driver module is connected to the respective end terminal of its respective stator winding without a parasitic impedance of any significance being present in between said driver module and said stator winding.
