Abstract
The utility model discloses an electromagnetically driven device, comprising an electromagnetically driven part and an electronic switch circuit. The electromagnetically driven device can replace a motor, and therefore, the electromagnetically driven device has simple production and manufacture, convenient maintenance and low working temperature. When a rotating part is blocked and stopped rotating, a coil automatically cuts off a power supply, so the electromagnetically driven device can not generate a burning phenomenon, and meanwhile, the utility model has obvious power saving effect, after an electric fan adopts the electromagnetically driven device, the electromagnetically driven device can save power by 30-90% under identical conditions.
Description
The utility model relates to a kind of electromagnetic actuator device.
The electromagnetic actuator device that uses mainly is to exchange or DC motor now, because the motor manufacturing technology complexity, so the cost height, repairing acquires a certain degree of difficulty.When the motor rotating part is subjected to very big resistance, when especially stuck phenomenon taking place, electric current can sharply rise, and makes coil heating, even burns.
The purpose of this utility model be design a kind of manufacturing technology simple, repair convenience, power consumptive province, electromagnetic actuator device that working temperature is low.
Electromagnetic actuator device of the present utility model comprises housing, support body and fulcrum, it is characterized in that: in the support body outer end permanent magnet is housed, signal coil and actuating coil are housed on housing, its position is just in time corresponding with permanent magnet; Actuating coil is received by DC power supply and switch on the collector and emitter of transistor, and the signal coil two ends join with the base stage and the emitter of transistor respectively.
During work, when support body when fulcrum rotates, the permanent magnet that drives the support body outer end skims over signal coil, cutting magnetic line, according to electromagnetic principle, produce voltage at the signal coil two ends, this voltage is added to the transistor base stage, between base stage and emitter, produce base current, so the transistor conducting by DC power supply switch, makes and flows through bigger collector current in the actuating coil like this, produce magnetic field, the permanent magnet that promotes the support body outer end continues rotation.After permanent magnet left signal coil, signal coil can not produce enough base voltages, made transistor be in cut-off state, did not just have electric current to pass through like this in the actuating coil, and magnetic field disappears.But this moment, support body etc. was because inertia continues rotation, and permanent magnet skims over signal coil on another support body, and during cutting magnetic line, signal coil produces enough big base voltage again, and transistor is open-minded, repeats said process again, moves in circles with this, the commentaries on classics of not stopping transport.
In addition, the technology that can use existing adjustment voltage is adjusted the rotating speed of drive unit, to satisfy different needs.
This shows, the utility model is simple in structure, be easy to produce and maintenance, owing to use permanent magnet can reduce power consumption, and owing to use electronic switching circuit, so when rotating part is subjected to resistance and stops, obstructed overcurrent in the actuating coil, can not burn, in fan, adopt this structure after, actual economize on electricity 30-90%.
In the accompanying drawing, Fig. 1 is the schematic diagram of drive fan device.Fig. 2 is the circuit part schematic diagram.Among the figure: 1, transistor.2, crystal diode.3, capacitor.4, switch.5, switch.6, DC power supply.7, signal coil.8, actuating coil.9, permanent magnet.10, flabellum.11, shell.12, fulcrum.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated: be example with the fan, adopt existing magnetic orientation technology, it is corresponding to make flabellum 10 be in the position of coil 7,8 on permanent magnet 9 fixing on relative position flabellum 10 outer ends of Fig. 1 and the shell 11 when rotation stops.During startup, Closing Switch 4 is because switch 4 is chain with switch 5, when switch 4 closures, switch 5 is opened, DC power supply 6 is by diode 2 like this, and the actuating coil 8 of switch 4 and series connection is to capacitor 3 chargings, when electric current passes through actuating coil 8, produce magnetic field,, make flabellum 10 around fulcrum 12 rotations with permanent magnet 9 interactions fixing on flabellum 10 outer ends.When capacitor 3 chargings finished, this loop no current passed through, and magnetic field disappears in the actuating coil 8, but because inertia makes flabellum 10 continue rotation.When a permanent magnet 9 skims over signal coil 7, signal coil 7 two ends produce voltage, and be added on the base stage of transistor 1, form base current, make transistor 1 conducting, at this moment actuating coil flows through bigger collector current, thereby produces magnetic field, the permanent magnet 9 that promotes flabellum 10 outer ends continues rotation, when permanent magnet 9 left signal coil 7, signal coil 7 just can not produce enough base voltages, made transistor 1 be in cut-off state, like this, do not have electric current to pass through in the actuating coil 8, magnetic field is disappeared, but this moment is because inertia, flabellum 10 and permanent magnet 9 continue rotation, when another permanent magnet 9 skims over signal coil 7, during cutting magnetic line, produce enough base voltages, repeat said process, make flabellum 10 not stop rotation.When stopping, Closing Switch 5 is also just opened switch 4, disconnects DC power supply, shuts down.For reaching the speed governing purpose, can adopt existing stepless pressure regulation technology or dividing the retaining voltage-regulating technique to realize.Transistor 1 in the said apparatus, crystal diode 2, capacitor 3 can fit together, and are fixed on the shell 11 of device.
