ROTARY ELECTRIC MACHINE INTEGRATED WITH CONTROL DEVICE

摘要

A rotary electric machine integrated with a control device includes: a housing composed of a front bracket and a rear bracket and supporting a rotor and a stator; and a control device attached to the rear bracket. The control device is composed of: a power module having a switching element that is for energizing a stator winding of the stator; a field module having a switching element that is for energizing a field winding of the rotor; a heat sink cooling the power module and the field module; and a control board having a control circuit that controls the switching elements, the control device also including: a battery end terminal; and a grounding end terminal. Then, the heat sink is attached to the rear bracket while being insulated therefrom.
