Fig. 2 is the utility model operation principle schematic diagram.
Wherein, 1 is motor; 2 is electromagnetic brake; 3 is electron rectifier.
Embodiment
As shown in Figure 1, electron rectifier 3 power supplies that electromagnetic brake 2 adopts, the electricity that obtains is single.
As shown in Figure 2, a kind of novel electron rectifying device, the external cabling of described electronic rectifier device is same as in figure 1, and is simple and convenient.Input is connected with three phase electric machine 1, and output is connected with electromagnetic brake 2.
The concrete course of work is as follows:
The utility model is a kind of time variant voltage rectifier of novelty, and its operation principle as shown in Figure 2.When motor begins electricly, electronic switch S1, S2 are closure state, time variant voltage rectifier output HIGH voltage offers electromagnetic brake 2, accelerate the foundation in electromagnetic brake 2 magnetic fields, make electromagnetic brake 2 rapid adhesives, treat electromagnetic brake 2 complete adhesives after, electronic control circuit disconnects electronic switch S1, low-voltage of time variant voltage rectifier output offers electromagnetic brake 2, guarantees electromagnetic brake 2 normal adhesives.When motor is shut down, i.e. electromagnetic brake 2 dead electricity, electronic control circuit disconnects switch S 2; cut off electromagnetic brake 2 DC channel rapidly, make electromagnetic brake 2 coil currents descend field weakening fast; electromagnetic brake 2 discharges, and makes the rapid brake application stoping of motor.
Compound rectification circuit operation principle
In theory, under the influence of ignoring correlative factors such as rectifier diode tube voltage drop, pass between the VD mean value Ud1 of single phase bridge type rectifier circu and the AC-input voltage effective value U is Ud1=0.9U, pass between the VD mean value Ud2 of single-phase half-wave rectifier circuit and the AC-input voltage effective value U is Ud2=0.45U, if we make rectification circuit can be operated in single-phase bridge, two kinds of rectification states of single-phase half-wave respectively, just can obtain to differ 1 times high and low two kinds of direct voltage Ud1, Ud2.
Output voltage U d depends on the state (being rectification state) of electronic switch S1, Ud=Ud1 output HIGH voltage when S1 is closed, Ud=Ud2 output LOW voltage when S1 disconnects.
The control principle of high and low two kinds of voltage transitions is a time principle, and promptly S1 is that time control switch is rectifier S1 closure when beginning electricly, treats S1 disconnection after the electromagnetic brake 2 complete adhesives through certain hour.
The utility model compared with prior art, the technique effect that mainly brings is as follows:
1, in the cycle of 2 one energisings of electromagnetic brake adhesive, because high pressure proportion pickup time very Little, produce bigger exciting current in the time of therefore in the design of brake, can making the high pressure adhesive, thereby form bigger The suction-combining force, accelerate attracting process, the situation that brake does not also discharge fully when having avoided motor start-up.
2, increase owing to air gap reduces magnetic flux after electromagnetic brake 2 adhesives, electromagnetic brake 2 reasonably is set Technical parameter can reduce average exciting current, thereby reduces the solenoid wire diameter, reduces copper consumption. Excitation Winding volume reduces, and causes the brake volume to reduce, and can reduce again the iron amount of using.
Exciting current is littler during 3, owing to the maintenance adhesive, thus easier when electromagnetic brake 2 dead electricity discharge, Make braking effect better.
4, exciting current reduces, and the heat that magnet exciting coil is produced reduces, temperature reduces, and has improved brake Working environment.
5, because exciting current reduces, electromagnetic brake 2 energy losses are reduced.
