Problems solved by technology

As a parameter index of the motor, the moment of inertia has an impact on many performances of the motor: the moment of inertia will cause the electromechanical time constant of the motor to increase, the sensitivity will be poor, the torque fluctuation will be large, and it will not be stable at low speeds. Bring radio interference and affect the life of the motor, so that the use of the motor is limited

Abstract

The invention discloses a permanent magnet wind-driven motor with low rotational inertia, and belongs to the technical field of special motors. The permanent magnet wind-driven motor comprises a shaft, an armature iron core, first armature windings, second armature windings, a rotor iron core, permanent magnets, a permanent magnet iron core and a shell, and is characterized in that 4k fan-shaped through holes are uniformly formed in a disc of the rotor iron core, and the k is a positive integer; the permanent magnet iron core and the armature iron core which are fixed onto the shell are arranged on two sides of the rotor iron core, the 6k fan-shaped permanent magnets are arranged on the surface, which faces the rotor iron core, of the permanent magnet iron core, 12k fan-shaped protruded armature poles are uniformly distributed on the side, which faces the rotor iron core, of the armature iron core, each first armature winding is wound on the two corresponding armature poles, and the second armature windings are wound on the odd-number armature poles along the clockwise direction. The permanent magnet wind-driven motor has the advantages that the rotor iron core is low in rotational inertia and can quickly respond, the second windings are capable of weakening demagnetization armature reaction and increasing the power density, and accordingly the permanent magnet wind-drivenmotor is quite suitable to be used as a wind-driven power generator started by breeze.

Description

technical field [0001] A permanent magnet wind-driven motor with low moment of inertia, belonging to the technical field of special motors Background technique [0002] With the increasing depletion of resources and the strengthening of environmental protection awareness, wind power generators, as a renewable energy technology with competitiveness and development prospects, have been valued worldwide, and wind power generator technology has shown a momentum of rapid development. . Traditional wind generators include DC motors, asynchronous and synchronous AC motors. No matter what kind of motor, they are composed of two major components: stator and rotor. Depending on the rotation of the rotor in a changing magnetic field, the winding generates an induced electromotive force, thereby capturing the wind wheel. of wind energy into electricity. [0003] Permanent magnet wind motor has the characteristics of high power density, high efficiency, high reliability, low maintenanc...
