This design has been through having add damping mechanism between backup pad and base, produced vibration exerts an influence to its self structure when preventing motor operation, has prolonged the life of motor.
Description
Technical field
The utility model relates to a kind of permanent-magnet machine, particularly a kind of automobile high-precision micro motor.
Background technology
The baneful influence brought to environment due to atmosphere polluting problem and fossil oil are exhausted, the electromobile of electric motor is used to be attracted attention, wherein, be main power source taking engine, the hybrid vehicle that take electric motor as auxiliarypower source and even the electromobile that only electric motor is used as main power source developed and realized commercialization, thus the availability of electric motor is improved. But existing electric motor generally also exists the problems such as radiating effect is not good, so designing a kind of motor with great heat radiation effect to seem particularly important.
Summary of the invention
The utility model technical issues that need to address are by having additional damper mechanism between back up pad and base, prevent the vibration produced during motor operations from himself structure being had an impact, extend the work-ing life of motor; A kind of automobile high-precision micro motor is provided.
For solving above-mentioned technical problem, structure of the present utility model comprises machine shell, magnetic steel of stator, permanent magnet, rotor, rotation axis, back up pad and base, described machine shell is wrapped on the outside surface of magnetic steel of stator, described permanent magnet is provided with four pieces, four described block permanent magnets are arranged on four faces all around in magnetic steel of stator respectively, described rotor is movably connected between four block permanent magnets, the upper end of described back up pad is fixedly connected on the bottom of magnetic steel of stator, the lower end of described back up pad is connected on base, damper mechanism also it is provided with between described back up pad and base, the rotation axis of described rotor is also connected with torque force limiting device.
Further: on described rotation axis and torque force limiting device, corresponding position has offered keyway respectively, and described rotation axis is fixedly connected with torque force limiting device with the cooperation of key by keyway.
Further again: the outside surface of described machine shell is teeth shapes.
Further again: described damper mechanism comprises deoscillator and anti-vibrating spring, described deoscillator and anti-vibrating spring are arranged between back up pad and base respectively.
After adopting said structure, the utility model, by having additional damper mechanism between back up pad and base, prevents the vibration produced during motor operations from himself structure being had an impact, extends the work-ing life of motor;And it also has the advantage that structure is simple, be easy to manufacture and practicality and high efficiency.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
