Abstract
The utility model discloses an electromobile motor with a fan. The electromobile motor with the fan comprises a shell, an end cover, a stator, a winding, a permanent magnetic rotor and a rotating shaft, and also comprises the fan, wherein the fan is installed at the back of the rotating shaft and positioned inside the shell. By adopting the structure that the fan is installed at the back of the rotating shaft inside the shell, when the motor works, the fan rotates, so that the radiating effect of the motor is greatly improved and the service life of the motor is prolonged.
Description
Technical field
The utility model relates to a kind of motor, particularly relates to a kind of motor of electric motor car with fan.
Background technology
Electric vehicle motor generally adopts permanent magnet DC motor at present, and this motor electromechanical conversion efficiency is high, and this can reduce the electric current that goes to using the electric motor car of the vehicle-mounted limited energy, prolongs mileages of continuation.But present electric vehicle motor radiating effect is poor, so useful life is short.
The utility model content
The technical problem that the utility model will solve provides the motor of electric motor car of the band fan of a kind of good heat dissipation effect, long service life.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
The motor of electric motor car of the utility model band fan comprises casing, end cap, stator, winding, p-m rotor and rotating shaft, wherein also comprises fan, and fan is installed in the rear portion of rotating shaft, and fan is positioned at casing.
The motor of electric motor car of the utility model band fan, wherein said p-m rotor is made up of the multistage permanent magnet that is enclosed within the rotor rack in the rotating shaft and be contained on the rotor rack, and the multistage permanent magnet is arranged on the rotor rack vertically.
Fan is installed at the rear portion of motor of electric motor car rotating shaft in casing of the utility model band fan, and during machine operation, fan rotates, and has improved radiation effect of motor greatly, has prolonged the useful life of motor.
Be described further below in conjunction with the motor of electric motor car of accompanying drawing the band fan of the utility model.
Description of drawings
Fig. 1 is the structure cutaway view of the motor of electric motor car of the utility model band fan;
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
Like Fig. 1, shown in 2, the motor of electric motor car of the utility model band fan comprises casing 1, support 2, end cap 3, stator 4, winding 8, p-m rotor 5, fan 6 and rotating shaft 7, and casing 1 is made of one structure with support 2, is convenient to make.The two ends of casing 1 are provided with end cap 3, and end cap 3 and casing 1 link to each other through bolt.Rotating shaft 7 is installed in the casing 1, and the two ends of rotating shaft 7 are passed through Bearing Installation respectively in end cap 3.P-m rotor 5 is installed in the rotating shaft 7; P-m rotor 5 is made up of the multistage permanent magnet 52 that is enclosed within the rotor rack 51 in the rotating shaft 7 and be contained on the rotor rack 51; Multistage permanent magnet 52 is arranged on the rotor rack 51 vertically; Fig. 1 only demonstrates two sections permanent magnets, and it radially is the concentric circles form that the magnetic pole of permanent magnet distributes.Stator 4 is provided with winding 8, and winding 8 also can adopt coil.Fan 6 is installed at the rear portion of rotating shaft 7, and fan 6 is positioned at casing 1, has improved radiation effect of motor.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection range of the utility model claims.
