Embodiment Construction

[0019] The present invention will be further described below in conjunction with the drawings and embodiments.

[0020] Such as Figure 1-5 As shown (when pictures are available).

[0021] A brushless DC motor for fast switching between electric and gasoline modes of an automobile. It includes a housing 1, a rotor 2, a stator 3, a main shaft 4 and an end cover 6. The rotation 2 is fixedly mounted on a section of the main shaft 4 in the housing 1. The stator 3 is fixedly installed in the housing 1 and opposite to the rotor. The output end of the main shaft 4 is supported in the bearing 7, the bearing 7 is installed in the end cover 6, and the end cover 6 is fixed on the open end of the housing 1. The inner and outer sides of the bearing 7 are respectively positioned axially through the hole retaining ring 51 and the shaft retaining ring 52, such as figure 1 Shown; the stator coil 32 on the stator 3 is installed with a temperature sensor 33 (structure such as figure 2 As shown, the...

Abstract

The invention relates to a brushless direct current motor for car power-driven / gasoline mode rapid switching. The brushless direct current motor comprises a shell (1), a rotor (2), a stator (3), a main shaft (4) and an end cover (6); the rotor (2) is fixedly installed on the section, located in the shell (1), of the main shaft (4), the stator (3) is fixedly installed in the shell (1) and is opposite to the rotor (2), the output end of the main shaft (4) is supported to the interior of a bearing (7) which is installed in the end cover (6), and the end cover (6) is fixed to the opening end of the shell (1). The brushless direct current motor is characterized in that the inner lateral face and the outer lateral face of the bearing (7) are axially positioned through a check ring (51) for holes and a check ring (52) for shafts; a temperature sensor (33) is installed on a stator coil (32) of the stator (3) and is electrically connected with a car fan starting power source, when the temperature sensor (33) detects that the temperature inside the brushless direct current motor exceeds a set value, a car fan (10) is started to cool the brushless direct current motor, and therefore the brushless direct current motor works at the temperature lower than the set temperature valve. The brushless direct current motor has the advantages of being small in size and reliable in connection.

Description

Technical field [0001] The invention relates to a DC motor for a vehicle, in particular to a DC motor for driving an oil pump for the conversion of the working mode of an electric / gasoline hybrid vehicle, in particular to a brushless DC motor for fast switching of the electric / gasoline mode of an automobile Motor. Background technique [0002] As we all know, in order to achieve energy conservation, environmental protection and reduce carbon emissions, the use of pure electric vehicles is a development trend. However, pure electric vehicles are not suitable for long-distance driving due to their short driving range, and long charging time and inconvenience have affected the development of pure electric vehicles. Therefore, at this stage, electric and gasoline hybrid vehicles are favored by environmental protection enthusiasts. They can play a role in urban and short-distance driving without affecting long-distance driving. However, the existing electric / gasoline hybrid vehicles ...
