A motor is electrically connected, without the use of a cable, by external male connectors which are mated with female connectors by the movement of the motor as it is installed. This facilitates automated assembly. Fig. 1 shows motor 10 with external male connectors 11 which are internally connected to the motor windings. Fig. 2 shows the details of a mating connector 20. Pairs of spring contacts 21 form female connectors for each male connector on motor 10. Spring contacts 21 extend through the body of connector 20, providing pins 22 to mount and electrically interconnect connector 20 to motor control circuit board 30, as shown in Fig. 3. Motor 10 is installed, starting in the relative position shown in Fig. 1, by movement in the direction of arrow 12, followed by rotation in the direction of arrow 13 as shown in Fig. 3.
