More Information
Summary:The disclosure is directed to a motor/generator including a magnetic circuit that is created between a rotor and stator through a first air gap and a second air gap so that a magnetic field (magnetic flux) passes through two parts of the edges of multiple stator teeth parts. A first protruding end part and a second protruding end part of the stator teeth parts which face each air gap may contain different shapes with regard to the circumferential direction of the rotor. These shapes and orientation of the first and second protruding end parts may reduce the cogging torque of the motor/generator.
