Embodiment Construction

[0038] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] The invention designs a rotor multi-slot type induction excitation hybrid excitation motor. The stator armature winding is placed in the stator slot, and the rotor DC excitation winding is placed in the rotor slot. The rotor yoke windings are placed in the slots, and additional rotor slots are provided on each rotor pole. One end of the additional rotor slots is connected to the corresponding rotor yoke slot, and the other end extends to the edge of the rotor pole shoe. A permanent magnet is set on the rotor core. The rotor yoke The winding is connected to the rotor DC field winding through a rotating rectifier.

[0040] figure 1 As a structural example of the stator part of the present invention, direct current can be introduced into the stator excitation winding 3 to establish a static additional magnetic field in the air gap; alt...

Abstract

The present invention discloses a rotor multi-slot type induction excitation type hybrid excitation motor. A stator armature winding is arranged in a stator groove, a rotor direct current excitation winding is arranged in a rotor groove, a plurality of rotor yoke part grooves are uniformly formed in a rotor iron core yoke part, a rotor yoke part winding is arranged in each rotor yoke part groove, a rotor additional groove is formed in each rotor pole body, one end of each rotor additional groove is communicated with the corresponding rotor yoke groove, the other end of each rotor additional groove extends to the edge of the rotor pole shoe, a permanent magnet is arranged on the rotor iron core, and the rotor yoke winding is connected with the rotor direct-current excitation winding through a rotary rectifier. The brushless slip ring is free of an electric brush, an exciter does not need to be additionally arranged, brushless excitation of the hybrid excitation motor can be achieved, and wide-range adjustment of the output voltage can be achieved.

Description

technical field [0001] The invention belongs to the field of brushless excitation motors, in particular to a hybrid excitation motor. Background technique [0002] For the rotor magnetic pole motor, how to realize the power supply of the rotor DC excitation winding is a difficult point in the design of this kind of motor. Brushless excitation is very important for special occasions such as aerospace, oil refining and mining. If the brush slip ring is still used to supply power to the DC excitation winding of the rotor, its safety cannot be guaranteed. For this reason, it is necessary to study the brushless of this kind of motor. Contents of the invention [0003] In order to solve the technical problems mentioned above in the background technology, the present invention proposes a rotor multi-slot induction excitation hybrid excitation motor. [0004] In order to realize above-mentioned technical purpose, technical scheme of the present invention is: [0005] A rotor mu...
