Description

Technical Field

[0001] This application relates to the field of cooling equipment, and in particular to an integrated vector reluctance electronic fan motor. Background Technology

[0002] During operation, cars need to dissipate heat from their components, especially the engine. The electric fan is an important part of the car's cooling system. The electric fan is driven by a motor, and it runs continuously as the engine runs. An excellent electric fan motor should be efficient, low-noise, and energy-saving to meet the stringent requirements of modern cars for their cooling systems.

[0003] Currently, the electric fan motors on the market are mainly brushed DC motors and brushless DC motors. Whether it is a brushed DC motor or a brushless DC motor, they are all driven by permanent magnets in conjunction with a rotor with coils. However, the main working environment of the heat dissipation equipment is the high-temperature area inside the car. Affected by the high temperature, the permanent magnets in the motor are prone to demagnetization and other phenomena, which will lead to a decrease in the power of the motor or even failure to rotate normally. Utility Model Content

[0004] To reduce the impact of high temperature on motor rotation, this application provides an integrated vector reluctance electronic fan motor.

[0005] The integrated vector reluctance electronic fan motor provided in this application adopts the following technical solution:

[0007] By adopting the above technical solution, the magnetic reluctance of the stator coil is controlled by controlling the current of the stator coil. The metal rotor is driven to rotate by the principle of minimum magnetic reluctance. No permanent magnets are set in the motor housing, which avoids demagnetization caused by high temperature and reduces the impact of high temperature on motor rotation.

The metal rotor and the motor stator are both installed inside the motor outer shell through the through hole. The motor rear end cover is installed at the through hole of the motor outer shell by means of a mounting cover. A fixing bolt is provided between the motor rear end cover and the motor outer shell. The motor rear end cover is detachably installed on the motor outer shell by means of the fixing bolt.

[0009] By adopting the above technical solution, the motor rear end cover can be detachably installed on the motor housing by fixing bolts.

[0011] By adopting the above technical solution, the mounting bracket can facilitate the installation of the motor housing on the vehicle.

[0012] Optionally, the mounting bracket is mounted on the motor housing using the fixing bolts.

At the same time, it makes reasonable use of space, making the overall structure of the motor more compact and reducing the overall size of the motor.

[0014] Optionally, a controller is installed on the side of the motor rear end cover away from the motor housing.

[0015] By adopting the above technical solution, the controller that controls the stator coil current is installed on the motor housing, eliminating the need for an additional controller installed inside the vehicle, thus facilitating motor control.

[0017] By adopting the above technical solution, the controller is integrated and installed between the controller housing and the motor rear end cover. The controller housing and the motor rear end cover house and protect the integrated controller, reducing the structure of the controller. The space is rationally utilized to make the overall structure of the motor more compact and the overall size of the motor smaller.

[0018] Optionally, the rear end cover of the motor has a groove on the side opposite to the motor housing, and the groove houses the integrated controller.

[0019] By adopting the above technical solution, the opening of the slot further reduces the overall size of the motor.

[0020] Optionally, the controller housing is mounted to the motor housing using fixing bolts.

[0023] The magnetic reluctance of the stator coil is controlled by controlling the current of the stator coil. The metal rotor is driven to rotate by the principle of minimum magnetic reluctance. No permanent magnets are set in the motor housing, which avoids demagnetization caused by high temperature and reduces the impact of high temperature on motor rotation.

[0024] The motor rear end cover can be detachably installed on the motor housing using fixing bolts. This allows the motor housing to be opened at any time while the rear end cover is fixed, enabling maintenance of the components inside the motor housing.

[0025] The controller is integrated and installed between the controller housing and the motor rear end cover. The controller housing and the motor rear end cover are used to house and protect the integrated controller, reducing the size of the controller. The space is used to make the overall structure of the motor more compact and the overall size of the motor is smaller.

One end of the motor shaft 2 extends out of the motor housing 1 for mounting an electric fan. A motor rotor 3 is mounted on the motor shaft 2. The motor rotor 3 is a magnetic rotor, such as made of iron or copper. The motor shaft 2 drives the motor rotor 3 to rotate within the motor housing 1. A motor stator 4 is mounted inside the motor housing 1 and outside the motor rotor 3. The motor stator 4 has several stator coils 5 arranged circumferentially. Different current lines are connected to the several stator coils 5. By passing different currents through the several stator coils 5, the magnetic reluctance of the stator coils 5 is made different, thereby driving the motor rotor 3 to rotate through the principle of minimum magnetic reluctance. No permanent magnets are set inside the motor housing 1 to avoid demagnetization due to high temperature and reduce the impact of high temperature on motor rotation.
