Problems solved by technology

In traditional motors, due to the large mass of the rotor, the inertia of the rotor is often large, resulting in slow start or slow braking; at the same time, the volume of the rotor and stator is usually large, making the overall volume of the motor large

Abstract

The invention discloses a disc type motor with ultra-low inertia. The disc type motor comprises a shell, wherein a first stator is fixedly arranged in the shell; the first stator is matched with a rotor in parallel; the rotor comprises a coil winding area and is fixedly connected with a rotating shaft; the first stator is fixedly connected with a first wireless power supply module; and the rotor is fixedly connected with a second wireless power supply module which is matched with the first wireless power supply module. By arranging the plate-shaped rotor and a stator, the whole motor is flatter and has smaller size and higher rotating speed; the rotor is arranged to be a PCB, so the mass of a traditional rotor is reduced, and the inertia of the rotor is greatly reduced; and meanwhile, power is supplied to the PCB in a wireless power supply mode.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an ultra-low inertia disc motor. Background technique [0002] A motor, commonly known as a motor, refers to an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. In traditional motors, due to the large mass of the rotor, the inertia of the rotor is often large, resulting in slow start or slow braking; at the same time, the volume of the rotor and stator is usually large, making the overall volume of the motor large. Contents of the invention [0003] Aiming at the problems pointed out in the background technology, the present invention proposes an ultra-low inertia disc motor. [0004] Technical scheme of the present invention is realized like this: [0005] The ultra-low inertia disc motor is characterized in that it includes a housing, the first stator is fixedly arranged in the housing, the first stator is...
