Problems solved by technology

The conventional dual-channel flux switching permanent magnet motor forms two radially opposite coils into one channel, and the armature winding of each phase is composed of two parallel channels, so the lack of phase fault will cause the complementarity to be destroyed, making the fault The opposite potential is asymmetrical, and it is necessary to adjust the phase and amplitude of the non-fault phase winding current to achieve fault-tolerant control

Embodiment Construction

[0018] Taking a 12 / 10-pole self-fault-tolerant flux-switching permanent magnet motor as an example, its cross-sectional view is attached figure 1 shown. The self-fault-tolerant flux switching permanent magnet motor is composed of a stator 1, a rotor 2, a permanent magnet 3 and an armature winding 4; the stator 1 consists of 12 "U"-shaped stator cores and 12 "U"-shaped stator cores embedded in the middle The permanent magnets 3 are combined, and the permanent magnets 3 are distributed symmetrically to the center of the stator 1 . "U" shaped stator core and rotor core are pressed by silicon steel sheets figure 1 The shapes shown are stamped into stator core punches and rotor core punches respectively, and then a sufficient number of core punches and rotor core punches are stacked to form stator cores and rotor cores respectively. The armature winding 4 is a concentrated winding, and each coil winding straddles two teeth of the stator 1 . The 12 coils of the three-phase armatu...

Abstract

The invention discloses a self-fault tolerance magnetic flux switching permanent magnet motor in order to improve the reliability of a motor and a drive system thereof. The self-fault tolerance magnetic flux switching permanent magnet motor is a stator permanent magnet motor. A three-phase armature winding of a stator (1) is composed of an A-phase armature winding, a B-phase armature winding and a C-phase armature winding; a winding A1 and a winding A2 of the A-phase armature winding are vertical to each other; a winding A3 and a winding A4 of the A-phase armature winding are vertical to eachother; the winding A1 and the winding A2 are serially connected to an A-phase first channel (5); the winding A3 and the winding A4 are serially connected to an A-phase second channel (6); the A-phasefirst channel (5) and the A-phase second channel (6) are connected in parallel; and the B-phase armature winding and the C-phase armature winding are connected in a same mode with the A-phase armature winding. The invention has the advantages of simple structure, good self-fault tolerance performance, high reliability and high power density. A drive system composed of the self-fault tolerance magnetic flux switching permanent magnet motor is particularly suitable for high-reliability fields, such as aviation, military, mine steel rolling, and the like which require continuous operations.

Description

technical field [0001] The invention belongs to the technical field of motor manufacturing, and specifically relates to a self-fault-tolerant magnetic flux switching permanent magnet motor based on a double-salient pole structure, strong, low-cost, suitable for high-speed and high-temperature operating environments, and requiring high reliability for continuous operation of the system . Background technique [0002] With the continuous expansion of the application range of motors in military, industrial, civil and other fields, the reliability of motor drive systems has received more and more attention from scholars in related fields, especially in aerospace, military equipment, mine rolling steel, etc. Reliability is especially important in occasions with high requirements for operation. As far as the technical level is concerned, the ways to improve system reliability can be mainly divided into two types: redundancy and fault tolerance. In terms of the motor body, althou...
