Abstract
The utility model discloses a low-voltage permanent magnet AC (alternating current) frequency modulation motor for an electric forklift, which comprises a stand, a motor spindle, a stator and a rotor, wherein the stator and the rotor are arranged in the stand, the rotor is fixed to the motor spindle and adopts a permanent magnet, the stator adopts a multi-path parallel connection wire, and a sensor is arranged in the motor and on a back cover of the motor. In the low-voltage permanent magnet AC frequency modulation motor, the motor space is compact, the volume is smaller than that of a similar motor, and a production material of the motor is also saved; and the rotor is in a permanent magnetic steel structure, thereby energy consumption of an excitation device is avoided so as to achieve the energy-saving effect, and the defect of high failure rate of the excitation device is also avoided so as to prolong the service life of the motor.
Description
Technical field
The utility model belongs to technical field of motors, relates in particular to a kind of electri forklift low pressure permanent magnet AC frequency modulation motor.
Background technology
The permanent magnetism frequency modulation motor rotor that is used for electri forklift at present needs excitation unit to carry out excitation, and the stator of motor adopts traditional diffusing winding mode.Caused internal structure complexity, the part of permanent magnetic low voltage frequency modulation motor commonly used more,, wanted the little requirement of cube in the low voltage motor field so can not finely satisfy so volume is bigger.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, the electri forklift that volume is little low pressure permanent magnet AC frequency modulation motor.
A kind of electri forklift that the utility model provides low pressure permanent magnet AC frequency modulation motor, the stator, the rotor that comprise support, electric machine main shaft and be positioned at base inner, described rotor is fixed on the electric machine main shaft, and described rotor adopts permanent magnet, and described stator adopts the multi-channel parallel wiring.
Preferably, described motor internal and motor bonnet are provided with transducer.
Motor of the present utility model space compactness, littler than similar motor volume, the while has also been saved the production material of motor; Rotor is the permanent magnet magnetic steel construction, has avoided the loss of excitation unit to the energy, reaches energy-conservation effect, has also avoided the high defective of excitation unit failure rate simultaneously, so prolonged the useful life of motor.
