Abstract
The utility model discloses a photoelectric speed measuring apparatus for a printing motor, which directly measures the motor rotating speed with low manufacturing cost and without increasing the motor volume and achieves a precision of 306 PPR. The technical scheme has key points that a grooved type optical coupler is installed on the edge of a rotor; the photoelectric speed measuring apparatus uses the printing winding plug lap joint on the periphery of the rotor and intervals as gratings to directly convert the rotating speed of the motor into a number of pulse and provide an accurate feedback signal for controlling the stabilization of the rotating speed of the motor.
Description
Technical field
The utility model relates to a kind of speed measuring device of motor, and more particularly, it relates to a kind of photoelectrical velocity measure equipment of printed motor
Background technology
As everyone knows, because printed motor is compared with the phase-wound rotor motor of equal-wattage, former torque is big, inertia is little, thereby extensively is used in automation field.Measurement to the printed motor rotating speed is the important step of motor speed stabilizing control, utilizes the method for tachogenerator or rotor winding electric kinetic potential and current feedback can only reflect rotating speed of motor indirectly, can not reach accurate control.Nantong 120 serial grating belts that health machinery Co., Ltd the produces printed motor that tests the speed that shakes, adopted the method that on motor output shaft, installs grating additional, though can directly reflect rotating speed of motor like this, but increased a lot of manufacturing costs and increased the body of motor, and motor whenever circles and only produces 60 pulses, and control precision is not high.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of photoelectrical velocity measure equipment of printed motor, and this device manufacturing cost is very low, and does not increase the volume at motor.Motor whenever circles and can produce 306 pulses, has improved control precision.
The technical scheme that the utility model is taked is: the grooved optocoupler is installed on the edge of printing wound rotor, and the winding melting welding head on the rotor edge is inserted in the sensitization groove of grooved optocoupler, utilize the melting welding head of rotor periphery printing winding and at interval as grating, when the light of grooved optocoupler luminous tube was printed winding melting welding head and blocks, the sensitizing tube of grooved optocoupler did not have electric current to flow through; When the light of grooved optocoupler luminous tube was not printed winding melting welding head and blocks, the sensitizing tube of grooved optocoupler just had electric current to flow through.Along with the rotation of printing winding, its melting welding head is the light of shield slot type optocoupler luminous tube discontinuously, just has pulse current to produce on the sensitizing tube of grooved optocoupler, and the rotation that so just will print wound rotor is converted into pulse, and with lead-in wire this pulse is drawn.
Grooved optocoupler and lead-in wire all welds in the circuit board, the melting welding head of packing into and print winding at the sensitization groove of grooved optocoupler, and when the rotation of printing winding, with under the grooved optocoupler generation friction situation with screw wiring board is fastened on the main shaft disk of printed motor.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is the cutaway view in the printed motor of the utility model place.
Among the figure: 1. print wound rotor, 2. printing winding melting welding head, 3. grooved optocoupler, 4. screw, 5. wiring board, 6. lead-in wire, 7. electric machine main shaft disk.
Embodiment
Among the embodiment as shown in the figure, grooved optocoupler 3 is welded on the wiring board 5, all has installing hole on wiring board 5 and the electric machine main shaft disk 7.The sensitization groove of grooved optocoupler 3 is inserted printing winding melting welding 2, and guarantee that printing wound rotor 1 rotates flexibly, is fastened on grooved optocoupler 3 and wiring board 5 on the electric machine main shaft disk 7 with screw 4.The lead-in wire 6 that is welded on the wiring board 5 is drawn pulse signal.Printing winding melting welding 2 has 306, can obtain 306 pulse signals of revolution on lead-in wire 6.
