Description
Technical field
The utility model is related to motor field, more particularly to a kind of external rotor electric machine of dead electricity braking.
Background technology
With becoming increasingly popular for the electric vehicles such as electric vehicle, drive the wheel hub motor of hub rotation extensive by motor
Application band electric vehicle and other rotational structures, but the function of some wheel hub motors be only limitted to drive hub rotation, inside
Without containing electromagnetic brake, do not have electromagnetic brake function.
Patent announcement number is that the patent of CN202121438U discloses a kind of wheel hub motor, it is fixed by rotor, motor
Son, motor shaft, electric motor end cap four are most of to be constituted, and motor down-lead is arranged on motor stator；Electromagnetic braking is set in wheel hub motor
Device, electromagnetic brake are made of electromagnetic brake movable plate and electromagnetic brake stator；Electromagnetic brake movable plate is with electric motor end cap
Electromagnetic brake lead is arranged on electromagnetic brake for integrally connected；Motor down-lead goes out, electromagnetic system from one end punching of motor shaft
Dynamic device lead goes out from the other end punching of motor shaft, and the outside of wheel hub motor directly wraps up tire and constitutes driving wheel entirety.
In above-mentioned wheel hub motor, electromagnetic brake stator is fixed on motor shaft, when being powered to electromagnetic brake, electromagnetism
Brake movable plate is attracted with electromagnetic brake stator, is rubbed to make electromagnetic brake movable plate be formed with electromagnetic brake stator,
And electromagnetic brake movable plate is fixed together with electric motor end cap, therefore, electric motor end cap is slowed down, and then is made solid with electric motor end cap
Fixed rotor is braked.
For above-mentioned wheel hub motor, electromagnetic brake is switched under state and brakes, therefore, this electromagnetic braking
Device, which is called, is made electric electromagnetic brake, and therefore, under power failure state, electromagnetic brake movable plate and electromagnetic brake stator are to be in
The state of separation so that electromagnetic brake does not have braking action.However, it has been found that for the occasion having, such as electricity
Motor on wheelchair, occupant are located on wheelchair and operate wheelchair when driving, and the motor of driving wheelchair traveling is necessarily in
Energized state, if using electric electromagnetic brake, although can be braked to wheelchair, in some cases, example
Such as, the electric quantity consumption of battery finishes or during wheelchair is run at high speed because failure powers off suddenly, and at this moment, wheelchair is in inertia
It will continue to travel under effect, carriage for the handicapped people on wheelchair, can not brake wheelchair, therefore right
There is great security risks for the handicapped people on wheelchair for carriage.In addition, in the occasion that some need parking,
It is necessarily in the state of dead electricity due to obtaining electric electromagnetic brake, also just loses the effect of brake, therefore, obtains electric electromagnetic braking
Device is unable to ensure the safety of parking.
Invention content
The external rotor electric machine for the dead electricity braking that the purpose of this utility model is to provide a kind of for improving safety.
The technical solution for solving above-mentioned technical problem is as follows：
A kind of external rotor electric machine of dead electricity braking, including mandrel, stator, magnet steel and the first outer rotor with cavity,
