Abstract
In the rotating electrical machine with integrated control device provided with the drive unit and the inverter assembly, the brush holder that holds the brush is detachably attached to either the rear bracket side of the inverter assembly or the inverter assembly side of the rear bracket so that it is not necessary to provide a hole for incorporating the brush holder in the central part of the control module, and the radial dimension of the control module can be reduced.
Claims20
A rotating electrical machine with integrated control device comprising:
- a drive unit having a rotor having a field winding, a stator and a rear bracket, and
- an inverter assembly arranged on the rear side of the drive unit and having a slip ring provided on the outer circumference of the rotating shaft of the rotor, a field module that supplies a field current to the field winding via a brush that is in sliding contact with the slip ring, heat sink thermally connected to the field module, and a control module disposed on the rear side of the heat sink for controlling the field current by controlling the field module,
- wherein;
- a brush holder that holds the brush is detachably attached to either the rear bracket side of the inverter assembly or the inverter assembly side of the rear bracket.
