In a motor, a stator with a three-phase winding set and a rotor are located in an operation region of a motor casing having a side wall. An inverter circuit constructed with power modules is located in a control region that is located on the opposite side of the operation region across the side wall in an axial direction of the motor. Each power module has a pair of transistors and a common terminal connected to the pair of transistors. A lead of a winding corresponding to one phase and a lead of a winding corresponding to another phase extend in the axial direction to cross over from the operation region to the control region and are connected together to the common terminal of a corresponding power module.
