Abstract
The utility model relates to a velocity feedback circuit structure used for an air-conditioning fan motor. The structure comprises a magnetic shoe rotating along with a rotating shaft in the housing of the motor and a circuit board used for automatically controlling the rotating speed of a rotor; and a Hall element which is used for inducing the magnetic signals of the magnetic shoe and is electrically connected with the circuit board is arranged in the place adjacent to the magnetic shoe. The control line of the circuit board and the power line of the motor are connected with an air-conditioning control circuit, and the regulation and control of the rotating speed of the motor is realized. The structure has the advantages that the structure is simple, the process difficulty of the motor stator is reduced, the multiple-stage speed regulation can be realized, the rotating speed is stable, and the stator turn-to-turn non-conforming rate is greatly reduced.
Description
Technical field
The utility model relates to a kind of speed feedback line construction of air conditioner fan motor.
Background technology
Indoor, the outdoor and dynamo-electric machine of window of the general branch of the asynchronous air conditioner fan motor of single phase alternating current (A.C.) of the prior art.Outdoor and window machine rotating speed of motor shelves generally have 1 grade, 2 grades, 3 grades, 4 grades, and normally the tap by main winding or auxiliary winding realizes.His shortcoming is the technology difficulty height, and coiling, rule, wiring be difficulty, also is easy to generate turn-to-turn, and at the bottom of the efficient of motor when low or first gear, rotating speed is the fixed gear of state.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, speed feedback line construction of realizing the air conditioner fan motor of multistep speed regulation, stabilization of speed.
For solving the problems of the technologies described above, the utility model provides a kind of speed feedback line construction of air conditioner fan motor, comprising: be located at the magnetic shoe that rotates with rotating shaft in the electric machine casing and be used for controlling automatically the circuit board of the rotating speed of rotor; Adjacently with described magnetic shoe be provided with being used to of being electrically connected with circuit board nearby and respond to the Hall element of the magnetic signal of described magnetic shoe.
Further, be provided with curved bracing frame in the described housing; Hall element is located at the front end of bracing frame and is extended to the adjoining position of described magnetic shoe, so that Hall element is extended to the position relative with described magnetic shoe, thereby receives magnetic signal.
The utlity model has positive effect: the speed feedback line construction of (1) air conditioner fan motor of the present utility model is the speed feedback line construction of the asynchronous air conditioner fan motor of single phase alternating current (A.C.), on rotor shaft, increase a signal magnet steel (being magnetic shoe) with rotor rotation, a circuit control board is installed on end cap in addition and is extended a support, the support head assigns a Hall element to be connected with circuit board, thereby receives magnetic signal.The control line of circuit board and the power line of motor are connected in the air-conditioning control circuit, realize the rotating speed of motor regulation and control.Its advantage is: simple in structure, the motor stator technology difficulty reduces, and can realize multistep speed regulation, and stabilization of speed lowers the turn-to-turn disqualification rate of stator greatly.
Description of drawings
Fig. 1 is the partial cross sectional views of speed feedback line construction of the air conditioner fan motor of embodiment 1;
Fig. 2 is the zoomed-in view of the local B among Fig. 1;
Fig. 3 is that the A of Fig. 2 is to view.
Embodiment
See Fig. 1-3, the speed feedback line construction of the air conditioner fan motor of present embodiment comprises: be located at stator 10 and rotor 11 in the electric machine casing 6, rotor 11 comprises rotating shaft 1; It is characterized in that: be provided with in a side of rotor 11 and be enclosed within the magnetic shoe 12 that rotates with rotating shaft 1 in the rotating shaft 1; The inwall of electric machine casing 6 is provided with the circuit board 9 and the curved bracing frame 3 of the rotating speed that is used for controlling automatically rotor 11, the front end of bracing frame 3 extends to the position adjoining with described magnetic shoe 12, and the front end of bracing frame 3 is provided with being used to of being electrically connected with circuit board 9 and responds to the Hall element 4 of the magnetic signal of described magnetic shoe 12.
Motor with speed feedback line construction is a kind of motor that has Hall element.Hall element is installed in the inside of motor, and just often blower fan whenever circles, and Hall element is exported one or several pulse signal.When fan motor rotational speed is high, its output pulse signal frequency height; When fan motor rotational speed was low, its output pulse signal frequency was low.The pulse signal of output is gathered by single-chip microcomputer, thereby adjusts the operating voltage of motor by adjusting the silicon controlled angle of flow then, carries out the automatic control of wind speed.
The foregoing description only is for the utility model example clearly is described, and is not to be qualification to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all execution modes.And these belong to conspicuous variation or the change that spirit of the present utility model extended out and still are among the protection range of the present utility model.
Claims (2)
