Abstract
The invention discloses a starting method of a direct current brushless motor of an air-cooled refrigerator. A control system is firstly used for judging whether the direct current brushless motor has a starting request, if the direct current brushless motor has the starting request and is not started, the direct current brushless motor is started for 5 seconds and stopped for 3 seconds, and the process is circulated for 3 periods so as to ensure complete startup of the motor. According to the invention, all kinds of risks of temperature rise of an air-cooled product caused by stalling of a fan in stoppage of the direct current brushless motor can be completely solved in a refrigerating process, and the level of the air-cooled series product is improved.
Description
Technical field:
The present invention relates to a kind of starting method of wind cooling refrigerator dc brushless motor, belong to the automation control of frost-free refrigerator motor.
Background technology:
At present, self there is defective in the wind cooling refrigerator dc brushless motor, during startup and environment temperature, fan is uneven, revolution, axial length, fan is heavy, oil mass, bearing material, there is motor only to start once can not to guarantee the possibility that can start fully in the impact that axial wood matter is relevant, be subjected to the conditions such as moment and flabellum shape.
If can change control method, adjust the cycle that starts, just can thoroughly solve the various risks that the wind cooling refrigerator blower fan does not start existence.
Summary of the invention:
For overcoming the defective of prior art, the object of the present invention is to provide a kind of starting method of wind cooling refrigerator dc brushless motor, this control method comprises the cycle of fan starting, the time that each cycle starts, and is controlled by the Electric Machine Control port.Break through traditional control method, design optimized control program, realize the startup of blower fan.
Technical solution problem of the present invention adopts following technical scheme:
A kind of starting method of wind cooling refrigerator dc brushless motor:
Control system is judged at first whether dc brushless motor has and is started request, if having the request of startup and motor not to open, then starts 5 seconds according to dc brushless motor, stops to control in 3 seconds, so circulates 3 cycles, starts fully to guarantee motor.
If have to start request and motor is opened, the then full timing zero clearing after 20 minutes of motor operation starts 5 seconds according to dc brushless motor, stops to control in 3 seconds, so circulates 3 cycles, starts fully to guarantee motor.
The rotating speed of described dc brushless motor is adjustable, and its rotating speed and frequency-changeable compressor energy are complementary, and the rotating speed of described motor per minute is controlled according to cooling load.
Compared with the prior art, beneficial effect of the present invention is embodied in:
The present invention thoroughly solves air-cooled product in process of refrigerastion, and dc brushless motor does not start the various risks such as temperature recovery that the blower fan stall of existence causes, and improves the level of air-cooled series of products.
Electric motor starting method of the present invention can normally be freezed, and the blower fan stall can not occur, and the reduction of the refrigerating efficiency that causes.
The present invention guarantees that motor normally starts, like this in the refrigeration process, in freezing process of refrigerastion, can not cause the risk of the temperature recovery that causes because of motor stalling, can not cause because motor stalling causes energy consumption yet and rise.
Description of drawings:
Fig. 1 is the starting method flow chart of dc brushless motor of the present invention.
Below pass through the specific embodiment, and the invention will be further described by reference to the accompanying drawings.
The specific embodiment:
Embodiment: referring to accompanying drawing, the starting method of wind cooling refrigerator dc brushless motor of the present invention, control system judges at first whether dc brushless motor has the request of startup, if the request of startup and motor are arranged not to be opened, then start 5 seconds according to dc brushless motor, stop to control in 3 seconds, so circulate 3 cycles, start fully to guarantee motor.If have to start request and motor is opened, the then full timing zero clearing after 20 minutes of motor operation starts 5 seconds according to dc brushless motor, stops to control in 3 seconds, so circulates 3 cycles, starts fully to guarantee motor.If the motor operation then kept motor to open state less than 20 minutes.The rotating speed of described dc brushless motor is adjustable, and its rotating speed and frequency-changeable compressor energy are complementary, and the rotating speed of described motor per minute is controlled according to cooling load.
