Embodiment Construction

[0018] Depend on figure 1 It can be seen that the composition of the tangential magnet double salient pole hybrid excitation motor of the present invention is composed of a permanent magnet structure with a common tangential magnet permanent magnet double salient pole motor on the stator and a unique electric excitation structure. That is, the stator composed of armature winding 6, stator N pole core 2, stator S pole core 4, permanent magnet steel 3, field winding 1, and the salient pole rotor core with the same structure as the ordinary double salient pole motor are equipped with the rotating shaft 8 Composed of rotors composed of 5 components, the above-mentioned structures are all installed in the casing 1. Among them, it must be ensured that there is an even number of permanent magnets, and at least two pairs of adjacent stator poles are not placed between permanent magnets, but are placed with excitation windings.

[0019] In addition, the number of poles of the motor st...

Abstract

This invention relates to tangential magnetic steel convex mixture excitation motor in double convex mixture excitation motor, which comprises the following parts: stator N iron center, stator S center, tangential magnetic permanent part, excitation set and rivet set, wherein, the above structure is located inside shell and when there is no excitation current at weak magnetic motor to avoid regular permanent motor.

Description

1. Technical field [0001] The invention relates to a tangential magnetic steel doubly salient pole hybrid excitation motor, which belongs to a doubly salient pole hybrid excitation motor. 2. Background technology [0002] In 1988, Professor Balagunov of the Moscow Aeronautics Institute proposed the structure of a parallel magnetic potential hybrid excitation synchronous generator. The stator is the same as the ordinary synchronous motor, and the rotor is divided into two parts, one part is permanent magnet excitation, and the other part is electric excitation. The characteristics of the motor: the electric excitation part is a claw pole structure, there are many additional air gaps, the axial magnetic circuit has large magnetic flux leakage, and the electric excitation function is restricted. [0003] Dr. T.Mizuno of Japan proposed an axial / radial magnetic circuit hybrid excitation synchronous generator. The stator armature winding of the motor is a common three-phase symm...
