Design of Brushless Synchronous Motor with an Inverter Integrated Rotor

This paper deals with the design of a brushless synchronous motor with an inverter integrated rotor instead of a brush and a slip ring. It is designed for 80kW output power and compared with an induction motor and a permanent magnet synchronous motor of the same specifications. Brushless synchronous motor, induction motor and permanent magnet synchronous motor have the same amount of magnet flux density at an air gap. As a result, the brushless synchronous motor can be reduced volume of motor and power losses comparing to the induction motor.
