Centralized power distribution member for motor with detachable auxiliary holder
First Claim
1. A centralized power distribution member for motor configured to feed power to windings of a stator of a multi-phase motor, comprising:
- a plurality of annular busbars each including a power feeding terminal and a connection terminal to be connected to one end of the winding of each phase, the power feeding terminals and the connection terminals being on one axial end edge of the respective annular busbar;
an annular holder made of synthetic resin and configured to accommodate the busbars laminated in a radial direction in a mutually insulated manner;
a neutral point busbar configured to connect the other end of the winding of each phase; and
an auxiliary holder made of synthetic resin and configured to accommodate the neutral point busbar,the auxiliary holder being arranged in an area of an end surface of the annular holder where the power feeding terminals and the connection terminals are arranged and being retracted radially inwardly of the outer periphery of the end surface, resiliently displaceable locking pieces formed on the auxiliary holder and being fit to locking protrusions formed on the annular holder to retain the auxiliary holder on the annular holder.
