摘要： A miniature motor with a two-pole stator, and a rotor having three or more salient poles each having a core with flanges extending toward both sides thereof and a winding. The rotor is adapted to simulate a two-pole construction by cutting off at least the tip of a flange on either side on a part or all the salient rotor pole cores, thereby limiting the spontaneous-stop angular positions of the rotor to two. One insulating spacer is provided between a plurality of commutator segments of the commutator in such a positional relationship as to come in contact with one of the two brushes when the rotor is at a spontaneous-stop angular position. The motor is prevented from burning and restarting suddenly after a stop since the motor has a self-inactivating function by interrupting current supply at spontaneous-stop angular positions while maintaining motor torque by minimizing the angle of non-conduction to the rotor.

摘要： An ac motor comprises a dc micromotor with terminals passing through an insulating end bell to receive dc current from a rectifier module. The flat surface of the end bell contains fixing grooves and a hole. The rectifier module is fitted within the hole. Fixing bosses are also provided on the end surface of the end bell. An input terminal plate is provided with holes for engaging the four bosses. The input terminal plate is provided with cut grooves which delimit four input terminal portions. The input terminal plate also has a middle hole. The input terminal plate is pressed into engagement with the four bosses resulting in the input terminal plate separating into four input terminal pieces, which are bent into the fixing grooves and also bent into the hole to fixedly fit the input terminal pieces to the end bell. Terminals of the rectifier module are electrically and mechanically connected to be held by the input terminal pieces.
