Embodiment
Below in conjunction with the drawings and specific embodiments, concrete detailed description is further done to the utility model.
As shown in the figure, a kind of reducing motor, comprises mair motor, and described mair motor is provided with mair motor base 10.
Also comprise a brake gear, described brake gear comprise the brake block 1 of arc, the slide block 8 be fixedly connected with arc brake sheet 1, the leading screw 5 be threaded with described slide block 8, for controlling stepping motor 6 that leading screw 5 rotates and the control device 7 for control step motor 6 action, the output shaft 2 of the concave surface facing mair motor of described arc brake sheet 1 is arranged, and the convex surface of arc brake sheet 1 is fixedly connected with described slide block 8.
Also be provided with the brake frame 4 of an annular, brake frame can be fixed on mair motor base 10.
Brake frame 4 is fixed with slide rail 9, described slide block 8 matches with slide rail 9 and slides, and the output shaft 1 of described mair motor is also provided with transducer 3, and described transducer 3 is electrically connected with control device 7.
Described transducer 3 is any one in velocity transducer, angular displacement sensor, torque sensor or acceleration transducer, and described control device 7 can adopt a single-chip microcomputer.
Arc brake sheet 1 described in the present embodiment is two panels, respectively by respective leading screw and respective stepping motor, carries out coordinated signals driving by control device.
In practical application, described arc brake sheet 1 also can adopt four, and four arc brake sheets 1 adopt respective leading screw and respective stepping motor respectively, carry out coordinated signals driving by control device.
Described stepping motor 6 and control device 7 can be located on mair motor base 10.
The utility model adopts control device 7 to be analyzed by the signal come transducer 3 transmission, then stepping unit 6 is driven to drive leading screw 5 to rotate, thus order about slide block 8 and move forward and backward, overstock eventually through brake block 1 or unclamp the output shaft 2 of mair motor, realize the object of mair motor being carried out to speed governing, thus realize changing the moment of torsion of the output shaft 2 of mair motor.The utility model also by controlling the angular displacement (can coordinate and adopt angular displacement sensor) of mair motor, can realize the accurate location that mair motor rotates; By controlling speed and the acceleration (can coordinate and adopt velocity transducer and acceleration transducer) of mair motor rotation, thus the object to mair motor speed governing can also be reached.The utility model can be applicable to the precision instruments that microrobot, medicine equipment etc. need instantaneous high pulling torque, or needs pinpoint system.Structure is simple, and price is low, and speed governing amplitude is large, and speed governing is accurate, is not easy to make mistakes.
Operation principle of the present utility model: brake gear makes the output shaft 2 of mair motor slow down by brake block 1, produces stall magnetic resistance.Stall magnetic resistance makes the electric current of mair motor increase, and mair motor output torque also increases thereupon, realizes the object that mair motor increases moment of torsion.If the electric current that stall magnetic resistance produces is excessive, mair motor may be caused to burn.When the electric current of mair motor increases to a certain degree; protective circuit (protective circuit is prior art, does not describe in detail herein) in brake gear disconnects mair motor supply line, avoids burning mair motor; main motor output shaft 2 stops operating simultaneously, and brake gear resets.When mair motor moment of torsion needs to reduce, brake gear reduces skid resistance, and stall magnetic resistance reduces, and Main motor current reduces, and rotating speed increases, and mair motor moment of torsion reduces.
