Abstract
The utility model discloses a controllable plastic sealed brushless dc motor belonging to the technical field of the motor manufacture, comprising a plastic sealed casing 3 which is provided with a driving control circuit board 1 and a stator 6, a rotor 4, and a signal output device 2 which is arranged outside the plastic sealed casing; the signal output device is provided with four output interfaces (7) such as a power supply wire (anode) which is connected with the control circuit board, a power supply wire (cathode), a working voltage wire. When the motor operates, the signal can be transferred to the external connecting controller by the signal putout interface to be controlled and treated, and the closed-loop control and the numerical display of the motor can be realized.
Description
The utility model relates to a kind of controllable type plastic packaging brushless DC motor, belongs to the motor manufacturing technology field.
Have now Drive and Control Circuit plate and stator plastic packaging in the plastic packaging brushless DC motor in the plastic packaging casing, owing to there is not interface to the direct output speed signal in outside, the user can only carry out open loop control to motor according to the design load input parameter, because the manufacturing process error of motor itself and the influence of the discreteness of magnet steel performance, motor actual speed and design load in the running all can have certain deviation, is difficult to realize the accurate control to plastic packaging brushless DC motor rotating speed.
The purpose of this utility model provides the tach signal of the accurate output motor of a kind of energy, motor is realized the controllable type plastic packaging brushless DC motor of closed-loop control.
The utility model is a controllable type plastic packaging brushless DC motor, be packaged with the plastic packaging casing of Drive and Control Circuit plate and stator in comprising, place the rotating shaft of band rotor in the plastic packaging casing, it is characterized in that described plastic packaging casing also is provided with the signal output apparatus that links to each other with control circuit board outward, this signal output apparatus is provided with power line (positive pole), power line (negative pole), operating voltage line, four output interfaces of rate signal output line that link to each other with the Drive and Control Circuit plate.Also can be provided with electric capacity on the described signal output apparatus.
The utility model is by tach signal output interface on the Drive and Control Circuit plate, the tach signal of output motor exactly, make it to receive this signal on the display where necessary directly to show speed revolution value by handling, can also utilize this signal to remove to adjust the output parameter of main circuit, realize closed-loop control, reach the purpose of accurate control speed.
Accompanying drawing has provided structural representation of the present utility model;
Fig. 1 is an overall structure cutaway view of the present utility model;
Fig. 2 is the Facad structure schematic diagram of signal output apparatus described in the utility model.
Below in conjunction with embodiment the utility model is further described:
The utility model is mainly by the interior plastic packaging casing 3 that is packaged with Drive and Control Circuit plate 1 and stator 6, place the rotating shaft 5 of band rotor 4 in the plastic packaging casing, place outer signal output apparatus 2 formations such as grade that link to each other with control circuit board of plastic packaging casing, Drive and Control Circuit plate 1 and stator 6 plastic packagings are in the plastic packaging casing, and signal output apparatus is provided with power line (positive pole), power line (negative pole), operating voltage line, four output interfaces 7 of rate signal output line and the electric capacity 8 that links to each other with the Drive and Control Circuit plate.During motor rotation, rotating speed of motor signal and rotor-position signal are by the output of Drive and Control Circuit plate, and the rate signal output interface on signal output apparatus is given external controller, realize that closed-loop control and speed numerical value show.
