A motor control apparatus drives an inverter which supplies and receives electric power with respect to a motor by pulse width modulation. The motor control apparatus sets a frequency of a carrier such that a frequency of a sideband wave component of the carrier which is used for the pulse width modulation and a frequency of a predetermined rotation order of the motor become different from each other.

Motor control apparatus

A stator of a rotating electric machine includes a stator core provided with a plurality of slots along a circumferential direction, coils of a plurality of phases distributedly wound around the stator core via the plurality of slots, and an insulating paper disposed between the slot and the coil. The insulating paper has an adhesive portion which fixes the coil to the stator core and a part of the coil of each phase is fixed to the stator core by the adhesive portion.

Stator of rotating electric machine

A stator core of a rotary electric machine includes a yoke portion which has an annular shape, plural tooth portions protruding radially from an inner peripheral edge of the yoke portion toward a center, and plural fastening portions protruding radially outward from an outer peripheral edge of the yoke portion and each formed with a fastening member insertion hole through which a fastening member is inserted. The stator core is configured by a plurality of electromagnetic steel plates laminated via an adhesive layer. The yoke portion includes plural fastening portion inner regions, and plural non-fastening portion inner regions. The adhesive layer is disposed on the yoke portion. The adhesive layer includes at least one first adhering portion provided in each of the fastening portion inner regions, and at least one second adhering portion provided in each of the non-fastening portion inner regions.
