Utility model content
In order to overcome existing above-mentioned deficiency, the utility model provides a kind of motor of paper shredder deceleration of electrons device.
The utility model solves the technical scheme that its technical problem adopts: a kind of motor of paper shredder deceleration of electrons device, be made up of motor and brake apparatus, motor connects power supply, master switch is provided with between motor and power supply, motor connects from capacitor, carry Capacitance parallel connection brake apparatus, brake apparatus is made up of relay successively series diode A, diode B and electric capacity A.
According to another embodiment of the present utility model, comprise relay shunt capacitance B further.
According to another embodiment of the present utility model, comprise a diode C in parallel on circuit that relay and diode A connect further.
According to another embodiment of the present utility model, comprise the normally closed point of relay further and be connected between diode B and electric capacity A.
According to another embodiment of the present utility model, comprise relay normally open point further and connect a resistance.
According to another embodiment of the present utility model, comprise the direct current relay that relay is 500 Ω further.
According to another embodiment of the present utility model, comprising electric capacity A is further 47UF, 400V electrochemical capacitor.
The beneficial effects of the utility model are, the utility model utilizes capacitance energy storage charge-discharge principle to realize braking, and can promote in electromechanics trade, this similar application can at home electric, promote above garden instrument, main object allows client in use safer exactly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. motors, 2. brake apparatus, 3. power supply, 4. master switch in figure, 5. from capacitor, 6. relay, 7. diode A, 8. diode B, 9. electric capacity A, 10. electric capacity B, 11. diode C, 12. normally closed points, 13. often make war, 14. resistance.
Embodiment
If Fig. 1 is structural representation of the present utility model, a kind of motor of paper shredder deceleration of electrons device, be made up of motor 1 and brake apparatus 2, motor 1 connects power supply 3, master switch 4 is provided with between motor 1 and power supply 3, motor 1 connects from capacitor 5, from capacitor 5 brake apparatus 2 in parallel, brake apparatus 2 is by relay 6 successively series diode A7, diode B8 and electric capacity A9 forms, relay 6 shunt capacitance B10, a diode C11 in parallel on the circuit that relay 6 and diode A7 connect, the normally closed point 12 of relay 6 is connected between diode B8 and electric capacity A9, relay 6 often connects a resistance 14 battle 13, relay 6 is the direct current relay of 500 Ω, electric capacity A9 is 47UF, 400V electrochemical capacitor.
Operation principle:
When after closed master switch 4, motor 1 normally works, and the alternating voltage of motor from capacitor 5 two ends is through relay 6 simultaneously, and diode A7, diode B8 charge to electric capacity A9.
Because there is electric current to flow through relay 6 in the process of charging, relay 6 action, normal battle 13 is jumped in contact, and relay passes through diode A7, resistance 14 self-locking.
After master switch disconnects, relay 6 dead electricity, contact will from the normal normally closed point 12 of 13 rebound of making war, and now pass through diode C11 to motor 1 coil discharge from capacitor 5, the magnetic field that discharging current produces prevents the rotation of rotor, reaches braking object.
More than illustrate the utility model just illustrative; and it is nonrestrictive; those of ordinary skill in the art understand; when not departing from the spirit and scope that claims limit; many amendments, change or equivalence can be made, but all will fall in protection range of the present utility model.
