Abstract

PURPOSE:To improve the efficiency by shortening an armature winding which does not contribute to a generating torque and a time zone of the winding of such a state, thereby obtaining a strong rotary torque. CONSTITUTION:A field pole 9' has four poles magnetized at equal central angles of N- and S-poles. Five armature windings 4'-1-4'-5 are formed so that the central angle of the conductor which contributes to a generating torque is substantially equal to the width of the field pole 9'. Salient poles, on which the windings 4'-1-4'-5 are wound, are formed of a magnetic material, and have ten slots 3'-1-3'-10. The windings 4'-1-4'-5 are wound on the salient poles as a rotor 1', and the pole 9' is used as a stator.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a low torque ripple and is highly efficient.
＃'i芒〕Ll This is related to the 01 electric motor.

Conventionally, as shown in Figures 1 to 4,
There is a 5-phase, missing-type, 5-pole brushless DC sleeper in which the number of salient poles 2 is 511 as the identifier 1, and 5 Nariso sound glands 4 are wound around the 11q salient poles 2. In this electric motor, five salient poles are formed at equal intervals, so that a slot is formed between the two salient poles, and a total of five slots 6 are formed. 4 that contributes to the generated torque of armature wire 4
By inserting a conductor section in the 'lR direction, the salient pole 2 is equipped with an electric wire (see Fig. 2). Incidentally, in FIG. 2, the core wire ends pointing out at the top and bottom of the salient pole 2 are conductor portions that do not contribute to the generated torque. Now, 5 slots) 5-1. , 6-5, the armature windings 4-1, . . . , 4-5'r of 511 N are inserted, for example, as follows. 'Tun) Ikuko Street 4-1 is the dotted line part 5-1 of slot 6-1 and the dotted line part 5 of slot 6-6v.
