When air pressure is formed in cylinder, i.e., certain pressure is had to cylinder；And electromagnet is to be fixedly connected with cylinder, so electromagnet
A pressure is received, while being provided with self-regulated spring again between electromagnet and rack, which acts on self-regulated spring, self-regulated
Spring is compressed, and until stress balance, the air pressure in cylinder also reaches steady state value at this time；When needing to brake, electromagnet connection
Power supply, electromagnet can generate magnetic force, give friction plate fixed block one huge repulsive force, enable friction plate Rapid contact flywheel
It is braked.When Speed of Reaction Wheels is faster, the air-flow that blower generates is stronger, and electromagnet side of more turning left is mobile, i.e., closer to friction
Power fixed block, distance become smaller, then the instantaneous repulsion that friction plate fixed block is subject to is bigger, the braking efficiency (contact of friction plate
The pressure that speed and friction plate are subject to directly affects braking efficiency) it is higher.After friction plate contacts flywheel, under Speed of Reaction Wheels
Drop, the air-flow that blower generates reduce, and electromagnet can turn right movement again, electromagnet and friction plate fixed block distance increase, repulsion
Become smaller, the frictional force between friction plate and flywheel reduces.It can think that this programme is a kind of dynamic equilibrium mode of braking：One side
Revolving speed when face can be according to flywheel normal rotation selects initial brake efficiency, carries out fast braking；On the other hand it was braking
Cheng Zhong, the frictional force between friction plate and flywheel are gradually reduced, and until flywheel stopping, being avoided friction plate locking flywheel, are caused
Equipment damage.
2, the setting of circuit direction turning piece, reset spring, repulsion contact chip and suction contact chip, so that there are two types of electromagnet tools
Step mode.In friction plate compared with thick (friction disc wear is small), when friction plate fixed block linkage friction plate contacts flywheel, friction
Piece fixed block moving distance to the left is small, and circuit direction turning piece contacts repulsion contact chip, solenoid circuit forward conduction, braking at this time
Device is in normal operating conditions；With being consumed for friction plate, two circuit direction turning pieces are mobile to center when braking, reach a positioning
It postpones, circuit direction turning piece is no longer contacted with repulsion contact chip, but is contacted with suction contact chip, and solenoid circuit is reversely led at this time
It is logical, and the repulsion of electromagnet becomes suction, and friction plate fixed block back moves again by circuit direction turning piece toward pushing back, and circuit is again
Forward direction, and the above process is recycled, but flywheel does not contact with friction plate, and other components is protected to be damaged, at this time etc.
After flywheel stops naturally, friction plate can be replaced.
