Description
Technical field
The utility model relates to a kind of air conditioner brshless DC motor.
Background technology
As shown in Figure 1, conventional air conditioner adopts principal phase with alternating current machine or pays the mode of phase winding tap speed-regulating, makes the gear fixed connect thus realize speed-regulating function by speed-regulating switch, and after it exists motor making, gear rotating speed not easily regulates, and electric efficiency is lower, the shortcomings such as caloric value is large; Easily burn-down of electric motor is caused, poor stability after user's wrong line.
As shown in Figure 2, conventional air conditioner brshless DC motor is made up of motor body, motor driver and thermostat 3 parts, thermostat provides DC signal to motor driver, and motor driver collects DC signal rear drive motor body to carry out under a certain rotating speed.This kind of scheme because of the religion of thermostat price high, thermostat market price is 3 ~ 4 times of traditional speed-regulating switch, and its mode of connection and traditional AC motor have obvious difference, is unfavorable for marketing.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of air conditioner brshless DC motor, in maintenance brshless DC motor safety, efficiently, under the prerequisite of the characteristics such as rotating speed is adjustable, reduces cost and client's use cost of brushless electric machine.
The utility model solves the technical scheme that its technical problem adopts: a kind of air conditioner brshless DC motor, comprise brshless DC motor body, motor driver and speed-regulating switch, the input of speed-regulating switch is electrically connected with AC power, the output of speed-regulating switch is electrically connected with the input of motor driver, for providing working power and gear signal to motor driver, the output of motor driver is electrically connected with the winding leading-out wire of brshless DC motor body.
Further restriction, the output of speed-regulating switch comprises the fire wire output end of zero line output gear different from each, and the fire wire output end of each different gear provides working power and gear signal to motor driver.
Further restriction, motor driver has driver update interface.
Further restriction, motor driver has anti-wrong protected location.
The beneficial effects of the utility model are: the control realizing brshless DC motor and the rotational speed regulation that adopt speed-regulating switch, namely remain the advantage of brshless DC motor, again reduce the cost of brshless DC motor simultaneously.
Contrast with conventional air conditioner alternating current machine, there is energy-efficient characteristic, and caloric value is low, motor long service life.Contrast with conventional brushless DC motor, maintain safe, efficient, the characteristic such as rotating speed is adjustable of brshless DC motor, reduce manufacturing cost and client's use cost of brushless electric machine simultaneously.Can under user make the prerequisite changed, the alternating current machine of its former use of seamless replacement.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Fig. 1 is the structural representation of conventional air conditioner alternating current machine;
Fig. 2 is the structural representation of conventional air conditioner brshless DC motor;
Fig. 3 is structural representation of the present utility model;
In figure, 1. motor body, 2. motor driver, 3. speed-regulating switch.
Embodiment
As shown in Figure 3, a kind of air conditioner brshless DC motor, comprise brshless DC motor body 1, motor driver 2 and speed-regulating switch 3, brshless DC motor body 1 adopts brushless Hall-free mode, is mechanical energy by stators and rotators by electric energy conversion.
The input of speed-regulating switch 3 is electrically connected with AC power, the output of speed-regulating switch 3 is electrically connected with the input of motor driver 2, the output of speed-regulating switch 3 comprises the fire wire output end of zero line output gear different from 3, and the fire wire output end of 3 different gears provides working power and gear signal by 3 lead-out wires to motor driver 2.Speed-regulating switch 3 provides gear signal by the conducting of different gear to motor driver 2.Namely the lead-out wire of the fire wire output end of different gear is power line, is also the holding wire providing gear signal to motor driver 2 simultaneously.The lead-out wire of zero line output is zero line.
The output of motor driver 2 is electrically connected with the winding leading-out wire of brshless DC motor body 1.The AC conversion of speed-regulating switch transmission is the direct current that can drive brshless DC motor by motor driver, and by logical algorithm determination rotor-position, gathers the gear signal of speed-regulating switch, makes motor run under the rotating speed of setting after computing.Motor driver 2 has driver update interface, by realizing the flexible of rotating speed to the driver update of motor driver 2.
Motor driver 2 has anti-wrong protected location.When user's wrong line, can not burn-down of electric motor be caused and bring potential safety hazard.
Advantage is:
1. maintain the higher efficiency of brshless DC motor, reduce energy consumption;
2. adopt static stall mode of speed regulation, by the refreshable driver of spare interface to change each shelves rotating speed, flexibility is high;
3. reduce motor driver manufacturing cost;
4. motor driver carries the protection of wrong line, prevents burn-down of electric motor from causing security incident and property loss;
5. without the need to adopting thermostat speed governing, directly can use speed-regulating switch, reducing use cost;
6. contrast with alternating current machine, caloric value is low, prolongation motor useful life;
7. the mode of connection is consistent with traditional AC motor, facilitates the update of market volume motor.
