ELECTRICAL MOTOR HAVING CAPACITORS MOUNTED BETWEEN STATOR TEETH ABSTRACT OF THE DISCLOSURE An electrical motor is disclosed which has one or more capacitors inside the motor. Particularly, a half-pitch capacitor induction motor is shown, wherein the stator winding has a plurality of coils one each on a tooth of the stator, and an auxiliary or capacitor winding includes a plurality of coils one each on different ones of the teeth of the stator. The stator coils are spaced around the periphery of the stator such that spaces are provided between the coils, and one or more capacitors are provided in such spaces. These capacitors are mounted on an insulator board which provides physical mounting of the capacitors and also provides electrical connection to the capacitors to connect them all in parallel. The capacitors are then connected to the auxiliary winding. By this means, a small-sized motor without an elongated end bell permits mounting the capacitors inside the motor frame instead of outside in the usual cylindrical metal container.
