Abstract
The utility model discloses a speed feedback system for a motor, which belongs to the technical field of motor control. The speed feedback system for a motor comprises a motor shaft (1), a multipolar magnet ring (3), a Hall sensor (5) and a printed circuit board(4). The multipolar magnet ring (3) is arranged at the end of the motor shaft (1), and the Hall sensor (5) is fixed on the printed circuit board (4), and the test surface of the Hall sensor approaches to the cylinder outer surface of the multipolar magnet ring (3). The utility model has advantages of conducting detection feedback, rotating speed monitoring and rotating speed adjustment on a shaded pole motor; applying to other types of motors other than a shaded pole motor while obtaining the same use function.
Description
Technical field
The utility model relates to the electric machines control technology field, particularly a kind of reponse system that is used to detect motor speed.
Background technology
Motor with cup rotor is simple in structure because of it, the low various occasions that are widely used in a plurality of fields of cost, but, motor with cup rotor product does not in the market all have the speed feedback function, just can't adapt to when being used in monitor speed and adjusting the occasion that requires, and causes the product application space limited.
Summary of the invention
At the deficiency that existing product exists, technical problem to be solved in the utility model provides a kind of device that can detect feedback to the rotating speed of motor with cup rotor, be convenient to monitor speed and adjustment.
Technical solution adopted in the utility model is the rate feedback system of a kind of motor of design: comprise machine shaft 1, also include multi-pole magnet-ring 3, Hall element 5 and PCB4, multi-pole magnet-ring 3 devices are in the termination of machine shaft 1; Hall element 5 is fixed on the PCB4, and its test surface is near the outer round surface of multi-pole magnet-ring 3.
Simultaneously, for same inventive concept, also design a kind of rate feedback system of motor: comprise machine shaft 1 ｀, also include multi-pole magnet-ring 3 ｀, Hall element 5 ｀ and PCB4 ｀, multi-pole magnet-ring 3 ｀ devices are in the termination of machine shaft 1 ｀; Hall element 5 ｀ are fixed on the PCB4 ｀, and its test surface is near the end face edge of multi-pole magnet-ring 3 ｀.
Invention thinking of the present utility model is:
The rate feedback system of motor of the present utility model, be to utilize the multi-pole magnet-ring that rotates with machine shaft, with the velocity of rotation of motor by the Hall element sensing and be converted to electric impulse signal, being transferred to external equipment by PCB and lead-in wire again detects, thereby, solved the feedback problem of motor with cup rotor rotating speed effectively, be convenient to the monitoring and the adjustment of motor with cup rotor rotating speed, thereby, expanded the application space of motor with cup rotor.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cross-sectional schematic of the utility model along the A-A axis;
Fig. 3 is the structural representation of a special case of the utility model.
Among the figure: the 1st, machine shaft, the 2nd, motor, the 3rd, multi-pole magnet-ring, the 4th, PCB, the 5th, Hall element, the 6th, lead-in wire, 1 ｀ is the machine shaft of special case, 2 ｀ are motors of special case, 3 ｀ are multi-pole magnet-rings of special case, and 4 ｀ are PCB of special case, and 5 ｀ are Hall elements of special case, and 6 ｀ are lead-in wires of special case.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment one:
Present embodiment is to be a kind of printed circuit board by motor with cup rotor rotating shaft 1, motor with cup rotor 2, multi-pole magnet-ring 3, PCB4[PCB (PrintedCircuitBoard)], Hall element 5 and going between 6 constitutes.
Multi-pole magnet-ring 3 fixtures are in that (present embodiment adopts riveting to go into mode, also can adopt alternate manner) in the motor with cup rotor rotating shaft 1 (tail end) of motor with cup rotor 2, Hall element 5 is fixed on the PCB4, and allowing the test surface of Hall element 5 tightly fit in the outer round surface (but keeping certain clearance) of multi-pole magnet-ring 3 to prevent to produce mechanical friction, 6 connection PCB 4 and external equipments go between.
When motor with cup rotor 2 runnings, its machine shaft 1 rotates, because multi-pole magnet-ring 3 is that riveting is gone on the machine shaft 1, so multi-pole magnet-ring 3 rotates with machine shaft 1, and its rotational angular and machine shaft 1 are identical, thereby just can reflect the rotating speed of machine shaft 1 from multi-pole magnet-ring 3.Because multi-pole magnet-ring 3 surface distributed have multipole magnetic field, when multi-pole magnet-ring 3 rotated, multipole magnetic field alternately passed Hall element 5, and Hall element 5 is experienced magnetic field and produced electric impulse signal alternately and be transferred to external equipment by PCB4 and lead-in wire 6 and detect.
Embodiment two:
Present embodiment is a special case, is made of motor with cup rotor rotating shaft 1 ｀, motor with cup rotor 2 ｀, multi-pole magnet-ring 3 ｀, PCB4 ｀, Hall element 5 ｀ and 6 ｀ that go between.
Multi-pole magnet-ring 3 ｀ fixtures are in that (present embodiment adopts riveting to go into mode, also can adopt alternate manner) on motor with cup rotor rotating shaft 1 ｀ (tail end) of motor with cup rotor 2 ｀, Hall element 5 ｀ are fixed on the PCB4 ｀, and allowing the test surface of Hall element 5 ｀ tightly fit in the end face edge (but keeping certain clearance) of multi-pole magnet-ring 3 ｀ to prevent to produce mechanical friction, 6 ｀ connection PCB, 4 ｀ and external equipment go between.
The operation principle of present embodiment is identical with embodiment one.
The rate feedback system of motor of the present utility model both can be applicable to motor with cup rotor and had carried out rotating speed detection feedback and monitor speed and adjustment, also can expand on the motor that is applied to other types, obtained same function of use.
