What is an external lock brake?

The main spring compacts the brake block against the brake wheel through the brake arm, so that the brake is often in the closed (braking) state.
When the current is passed into the brake, the top column is lifted by electromagnetic action, and the brake arm is pushed through the push rod to loosen the brake shoe block and the brake.
The tile can be made of cast iron, or the cast iron can be covered with leather or asbestos tape, and the length of the push rod can be adjusted when the tile is worn.
The process of loosening the brake when the power is on and braking when the power is off is called normally closed. Normally closed type is safer, so it is widely used in lifting and transportation machinery and other equipment.
The release brake can also be designed to brake when powered on, and the release brake when powered off becomes normally open. Normally open brakes are suitable for braking vehicles.
Electromagnetic external block brake braking and opening fast, small size, light weight, easy to adjust the tile gap, replace the tile and electromagnet is also very convenient. However, the impact of braking is large, and the power consumption is also large, and it is not suitable for occasions where the braking torque is large and the need to start frequently.
Electromagnetic external holding block brake has a standard, can be selected according to the standard method.
