Abstract
A controller integrated rotating electrical machine is designed to minimize adverse thermal effects on a control device. The controller device includes switching modules, a control circuit, and a casing. The switching modules are disposed inside the casing at a distance from a rear housing. The control circuit is disposed in the casing and located in front of the switching modules at a distance from the rear housing and the switching modules. In other words, the control circuit is arranged away from the switching modules which are a heat source when operating, thereby eliminating adverse thermal effects on the control circuit.
Claims23
A controller integrated rotating electrical machine comprising:
- a rotating electrical machine which includes an armature winding disposed on a stator, a field winding disposed in a rotor, and a housing which covers axially opposed ends of the stator and the rotor;
- and
- a control device which includes a casing, switching modules, a control circuit, and brushes, the casing being secured to an axial rear end of the housing, the switching modules being disposed in the casing at a given distance from the housing and made up of inverter switching devices to deliver electric power to the armature winding, the control circuit being disposed in the casing and located in front of the switching modules in an axial direction of the controller integrated rotating electrical machine at an interval away from the housing and the switching modules, the brushes being disposed in the casing and located at a distance from the housing, the switching modules, and the control circuit, the brushes being at least partially located in front of the switching modules in the axial direction of the controller integrated rotating electrical machine and behind the control circuit in the axial direction of the controller integrated rotating electrical machine, the brushes working to deliver electrical power to the field winding.
