Embodiment Construction

[0033] Below in conjunction with accompanying drawing, the present invention will be further described.

[0034] The motor includes a stator, a rotor and a non-magnetic rotating shaft. It is characterized in that: the stator is set outside the rotor, and the permanent magnet is embedded in the stator core, which is divided into two parts: a full layer of stator yoke and an "E"-shaped stator core. The two parts are connected by magnetic bridges on both sides of the permanent magnet to strengthen the overall mechanical strength of the motor. The rotor is fixed on the non-magnetic rotating shaft, which is a salient pole type;

[0035] Stator consists of "E" shaped stator core, permanent magnet, three-phase armature winding, pulse winding and stator yoke;

[0036] Each stator core of the motor is "E"-shaped, and the two cavities formed inside include concentrated windings for placing the three-phase armature, while the middle fault-tolerant teeth will not wind the windings. The ...

Abstract

The invention discloses a fault- tolerant type stator segmentation flux switching memory motor which comprises a stator (1), a rotor (2) and a non-magnetic rotary shaft (8). The stator (1) is arranged outside the rotor (2), the rotor (2) is fixed to the non-magnetic rotary shaft (8) and is of a salient pole type, and the stator (1) comprises a stator iron core (1.2) with an opening at one end, a permanent magnet (3), a three-phase armature winding (4), a pulse winding (5) and a stator yoke (1.1). The stator iron core (1.2) comprises a bottom edge, a first magnetic iron core edge (1.21) and a second magnetic iron core edge (1.22), wherein the first magnetic iron core edge (1.21) and the second magnetic iron core edge (1.22) extend vertically from the bottom edge, the permanent magnet (3) is arranged between the bottom edge of the stator yoke (1.1) and the bottom edge of the stator iron core (1.2), and the stator iron core (1.2) further comprises a fault-tolerant gear (1.2.3) vertically extending from the bottom edge and arranged between the two magnetic iron core edges. The fault-tolerant type stator segmentation flux switching memory motor has a strong ability of operating with faults and a weak magnetic speed extension ability.

Description

technical field [0001] The invention relates to an adjustable flux permanent magnet fault-tolerant motor, in particular to a new type of three-phase flux switching permanent magnet memory motor, which can improve the motor's ability to operate with faults and weaken the magnetic field, and is suitable for wide speed regulation operation The invention belongs to the technical field of motor manufacturing. Background technique [0002] In the field of motors, due to the inherent characteristics of ordinary permanent magnet materials (such as NdFeB), the air gap magnetic field in the motor is basically kept constant, and the speed regulation range is very limited when operating as an electric motor. The application of wide-speed adjustable direct drive applications such as electric vehicles and aerospace is limited to a certain extent. Therefore, the adjustable flux permanent magnet motor aimed at realizing the effective adjustment of the air gap magnetic field of the permanent...
