Description
Technical Field
The utility model relates to an auto radiator fan motor.
Background
The cooling device of the automobile engine mainly uses water cooling, uses circulating water in a cylinder water channel for cooling, leads heated water in the water channel into a radiator, and returns the water channel after being cooled by wind. In order to improve the cooling capacity of the radiator, a radiator fan is required to be installed behind the radiator to forcibly ventilate. The key part of radiator fan is the motor, and traditional radiator fan motor, motor rear portion space is little, is unfavorable for the installation of motor control component, and for avoiding appearing the magnetic leakage simultaneously, motor casing generally adopts the thick steel sheet to make, and stretch forming is more difficult, and the precision is also not high, and in addition, the axial dimensions of motor is great.
Disclosure of Invention
In view of the deficiencies in the prior art, the utility model aims at providing a can make the motor rear portion leave bigger space in order to do benefit to the installation of motor control element, prevent the motor magnetic leakage simultaneously, the little radiator fan motor of motor axial dimensions.
The utility model adopts the following technical proposal to complete:
radiator fan motor has motor shaft and motor casing, its characterized in that: the motor shell comprises a front cylinder and a rear cylinder fixedly sleeved on the excircle of the front cylinder, the front cylinder is provided with a motor front end cover, the rear cylinder is provided with a motor rear end cover, an inner hole of the front cylinder is provided with a magnetic shoe, the length of the front cylinder is equal to or slightly greater than that of the magnetic shoe, a front bearing is arranged in the motor front end cover, a rear bearing is arranged in the motor rear end cover, and the motor shaft is rotatably supported by the front bearing and the rear bearing.
The rear shaft end of the motor shaft is provided with a commutator, and the end surface of the motor rotor opposite to the commutator is provided with a concave cavity for the commutator to partially enter.
According to the radiator fan motor in the technical scheme, the motor shell comprises the front cylinder and the rear cylinder fixedly sleeved on the excircle of the front cylinder, the magnetic shoe is arranged in the inner hole of the front cylinder, and the difference between the length of the front cylinder and the length of the magnetic shoe is not large, so that the rear space of the motor is large, and the installation of a motor control element is facilitated; in addition, the front cylinder and the rear cylinder are arranged at the mounting position of the magnetic shoe and surround together for magnetic isolation, so that the front cylinder and the rear cylinder can be made of thin steel plates, the stretching forming is convenient, and the precision is also improved; in addition, the end face of the motor rotor is provided with a concave cavity for partially accommodating the commutator, so that the axial size of the motor can be reduced, the structure is compact, and the installation space is saved.
Drawings
The utility model discloses there is following figure:
fig. 1 is a schematic structural diagram of the utility model.
Detailed Description
As shown in the figure, the utility model discloses a radiator fan motor has motor shaft 6 and motor casing, and motor casing includes preceding barrel 2 and fixed cover connect in the back barrel 1 of preceding barrel 2 excircle, preceding barrel 2 with motor front end housing 4, the 1 with motor rear end housing 8 of back barrel, the hole installation magnetic shoe 3 of preceding barrel 2, the length of preceding barrel 2 equals or slightly is greater than the length of magnetic shoe 3, is greater than the size and does not exceed 2mm, installs front bearing 5 in the motor front end housing 4, installs rear bearing 9 in the motor rear end housing 8, motor shaft 6 rotates the supporting by front and rear bearing, and commutator 10 is installed to the back axle head of motor shaft 6, and the terminal surface of the relative commutator 10 of motor rotor 7 is equipped with cavity 11 and lets commutator 10 parts get into wherein.
