摩擦式:是一种工作稳定可靠的制动器。一旦制动时,就会产出足够的负荷使运动件停动下来。当处于不制动的自由状态时,它们只有很小一点或没有残存制动力。这些制动器基本上是机械的电动式制动器。电动摩擦制动器有两种动作方式。一种是用电磁力来施加制动,当去除电磁力时,一个弹簧使制动器恢复自由状态。另一种是用一个弹簧的力或一个永久磁铁的吸力来施
Friction: It is a stable and reliable brake. Once the brake, it will produce enough load to stop the moving parts. When in a non-braking free state, they have little or no residual braking force. These brakes are basically mechanical electric brakes. Electric friction brake has two kinds of action. One is the use of electromagnetic force to apply the brake, when the removal of electromagnetic force, a spring brake to free state. The other is to use a spring force or a permanent magnet suction to cast
