Embodiment Construction

[0027] see in conjunction Figures 1 to 8 As shown, according to the embodiment of the present invention, the disc motor rotor includes a magnetic tile 1, an upper cover 2 and a lower cover 3, the upper cover 2 and the lower cover 3 are fixedly connected, and a fixing groove 4 is formed between the upper cover 2 and the lower cover 3 , The magnetic tile 1 is set in the fixed slot 4, and makes the motor rotor form a sinusoidal air gap magnetic field.

[0028] The rotor of the disc motor installs and fixes the magnetic tile 1 through the cooperation of the upper cover 2 and the lower cover 3 to form a fixing groove 4, which has high reliability and can ensure that the magnetic tile 1 is installed in place, the installation position is more accurate, and the structural strength of the rotor can be increased , improve the reliability of the rotor operation, and can be applied to high-speed applications. The magnetic tile 1 can make the motor rotor form a sinusoidal air-gap magneti...

Abstract

The invention provides a disc motor rotor and a disc motor. The disc motor rotor includes a magnetic tile (1), an upper cover (2) and a lower cover (3), the upper cover (2) and the lower cover (3) are fixedly connected, and the upper cover (2) and the lower cover (3) A fixing slot (4) is formed between them, and the magnetic tile (1) is arranged in the fixing slot (4), and makes the motor rotor form a sinusoidal air gap magnetic field. According to the disk motor rotor of the present invention, the sinusoidal air gap magnetic field is generated by the magnetic tiles, the air gap magnetic field has an obvious sinusoidal effect, the magnetic loss is greatly reduced, and the performance of the motor can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of motor equipment, and in particular relates to a disc motor rotor and a disc motor. Background technique [0002] With the development of motor technology, permanent magnet brushless DC motors are widely used in various places in various fields, and disc permanent magnet brushless motors are gradually used in various fields due to their compact structure and small size. Places with high structural volume requirements. The traditional disk motor rotor is usually glued to the rotor disk or the upper and lower rotor glands use screws to fix the magnetic steel to the iron core. The structure of this rotor will lead to low reliability during use. , suitable for low-speed occasions, and the rotor magnetic tiles are not bonded in place during production, which is prone to dynamic balance problems. [0003] A disk motor rotor is provided in the prior art. The disk motor rotor includes a rotor cover plate, a roto...
