The working principle of the driving brake system, the electrical working principle of the brake

The driving brake system is composed of a brake motor and a brake device, and when the brake motor is running, the brake device is opened. The main hook will drop with gravity.

The brake motor is divided into AC and DC type. The AC type cannot open the brake system after the power failure, and the inverter system needs to be added to open the brake motor and lower the main hook. The DC type can also put down the main hook through the DC power supply such as the battery when the power is out. Stay safe.

The super standard weight is between fat and slightly fat, in this case, the main thing is to see if the face is fat or not, the face is not fat, it can be regarded as slightly fat, and the face is fat.

Working principle: the motor is connected to the power supply, and at the same time, the electromagnetic brake coil is also electrified, the armature is engaged, and the brake shoe of the brake is separated from the brake wheel by overcoming the tension of the spring, and the electric reed machine is running normally. Disconnect the switch or contactor, the motor loses power, and the electromagnetic brake coil also loses power, the armature is separated from the iron core under the action of spring tension, and the brake shoe of the brake is tightly held by the brake wheel, and the motor is braked and stopped.

The control of the brake can be controlled in a variety of ways, such as relay or contactor logic interlock control, PLC programming control and the internal control of the inverter.

Generally, the control function of the inverter itself is realized, and the inverter outputs 24VDC to the relay when braking, and the relay drives the contactor to control the brake coil, and when the signal is output, the motor brake is opened, and it is in the braking state if it is not output. The advantage is that the speed of the motor controlled by the frequency converter is activated when it can be set artificially and is precisely reached. It satisfies the normal operation of the drive equipment.

The electrical working principle of the brake brake is: braking the moving machinery with electromagnetic force. When the rotating machinery or linear machinery is running, the electromagnetic brake is loosened under the use of spring force, and the machinery can operate, when the machinery needs to stop running, the current is passed into the electromagnetic coil of the brake, so that the magnetic field generated by the coil magnetizes the brake core, and the electromagnetic infiltration grip force is generated at the opening part of the core, so that the iron core is engaged, and the brake is driven to brake.

The structure of the electromagnetic brake is divided into brake solenoid and brake shoe brake. It is characterized by:

1. Mechanical braking mainly uses electromagnetic brake and electromagnetic clutch braking, both of which use the electromagnetic coil to generate a magnetic field after being energized, so that the static iron core produces a large enough suction force to attract the armature or moving iron core (the moving iron core of the electromagnetic plexus is attracted to the Qing clutch, and the dynamic and static friction plates are separated), overcoming the tensile force of the spring and meeting the requirements of the work site. The electromagnetic brake brake is to brake the brake wheel by the friction pads of the brake pads, and the electromagnetic clutch is to brake the motor immediately after powering off by using a large enough friction force between the dynamic and static friction plates.

2. Advantages: electromagnetic brake, strong braking force, widely used in lifting equipment. It is safe and reliable, and there will be no accidents due to sudden power outages.

3. Disadvantages: The electromagnetic brake is large in size, the brake is seriously worn, and it will vibrate when braking quickly.

Mechanical brakes are also called brakes. The general principle of operation of the braking system is to prevent the rotation or tendency of the wheels by using the friction between the non-rotating elements connected to the body (or frame) and the rotating elements connected to the wheels (or transmission shafts).

A metal brake drum with an inner circle as the working surface is fixed to the wheel hub and rotates with the wheel. On the immovable brake plate, there are two support pins that support the lower ends of the two curved brake shoes.

The outer surface of the brake shoe is equipped with a friction plate. The brake floor is also equipped with a hydraulic brake wheel cylinder, which is connected with the hydraulic brake master cylinder installed on the frame with an oil pipe. The pistons in the master cylinder can be operated by the driver via a brake pedal mechanism.

Mechanical brakes mainly play the role of deceleration and stopping, just like applying the brakes while driving.

The coil pin of the electromagnetic brake is connected in parallel with the motor;

2. If the motor is electrified, the coil of the electromagnetic brake is also electrified;

3. If the motor is out of power, the coil of the electromagnetic brake will also be out of power;

After the three-phase asynchronous motor cuts off the power supply, it needs to rotate for a period of time (or distance) to stop by inertia, while the hook of the starting machine or the hanging basket of the winch in production requires accurate positioning; The spindle of the universal milling machine needs to be able to stop quickly; After a sudden power failure, the elevator needs full protection and accurate positioning control....Wait. These require braking of the dragging motor, which is to give the motor a torque opposite to the direction of rotation to make it stop (or limit its speed) quickly. How to make loose dust eggplant.
