Stator segmentation and rotor blade integrated high-speed asynchronous motor

Abstract

The invention discloses a stator segmentation and rotor blade integrated high-speed asynchronous motor, which comprises a blade integrated slotless rotor, a segmented winding stator and a magnetic suspension bearing system for fixing the relative position between the blade integrated slotless rotor and the segmented winding stator, wherein the paddle integrated slotless rotor comprises a rotor iron core, paddles and a conductor layer, the conductor layer is arranged on the periphery of the rotor iron core, the paddles are uniformly arranged in the rotor iron core, the segmented winding stator comprises an arc-shaped stator iron core and a three-phase winding, the arc-shaped stator iron core is slotted along the inner side, and the three-phase winding is wound at the side slotting position of the arc-shaped stator iron core. The conductor layer is fixed on the outer surface of the rotor core, so that the manufacturing cost can be reduced, and the stability under a high-speed operation condition is improved. The sectional structure can save the material of the stator, reduce the cost of the motor, and improve the heat dissipation capability of the motor.

Description

technical field [0001] The invention relates to the field of high-speed asynchronous motors, in particular to a high-speed asynchronous motor integrating stator segments and rotor blades. Background technique [0002] High-power water pumps and fans are widely used in factories, buildings, tunnels and other occasions. At present, most equipment uses electric motors to drive the paddle shafts to realize the operation of water pumps and fans. For the blade, the end close to the motor shaft is usually called the blade stalk, and the end far away from the motor shaft is called the blade tip. In order to increase the stiffness of the propeller, the blade root needs to be thickened in the axial direction, but the blade tip should not be too thick. Obviously when the blade rotates, the thinnest blade tip is also the place with the highest linear velocity, so it is easy to generate vibration and noise. In addition, the water pump and fan system driven by a shaft motor has a large ...

Problems solved by technology

However, for large-scale fans (such as tunnel exhaust fans), the diameter of the fan is large, resulting in a large diameter of the stator of the integrated motor and high manufacturing costs. In addition, as for the rotor part of the motor, many permanent magnet rotors are currently used, and a special drive circuit is required. Start the high-power fan
