The YEJ2 series of three phase asynchronous motor brake by electromagnetic used in hang-basket is the new design for the hang-basket hoist which worked at high place. It is made up of main motor and additional AC (or DC) brake. There is manual tripping device in brake, so it can complete installation and debugging and to release when power cut.. There is no rectifier device in AC brake, and has short time to operate and braking. The shell’s material of motor and AC brake is quality Al-alloy. This equip has merits of small volume、light in weight、short time to braking、big brake torque and being convenient to maintain..
