Highly Integrated Electric Drive with Outer Rotor Motor

In conventional electric motor drive both the motor and the inverter are manufactured independently thus a large volume is required to accommodate the electric drive unit. These types of drive units also suffer from higher switching losses and large voltage overshoot due to the inductance of long wire. Miniaturization of the electric drive unit is a must for space-restricted applications such as electric vehicle traction application and more electric aircraft. We provide a new integrated drive topology.
