As to the preferred of the present invention, spacing guiding wall block is provided with and the brake block by the side of the sidepiece of brake block
The pre- rubbing action arc convex of sidepiece phase separation.Improve braking effect, it is ensured that the stabilization of braking procedure, reduce equipment damage.
As to the preferred of the present invention, the quantity of the tripping spring on the fixed steel loop of balance of rotor side is small
In the quantity of the tripping spring on the fixed steel loop of balance away from rotor side.The stability of motor operation is improved, simultaneously
Braking effect, and the effectively structure such as protection rotor are improved, damage is reduced.
As to the preferred of the present invention, the elasticity system of the tripping spring on the fixed steel loop of balance of rotor side
Number is equal to the coefficient of elasticity of the tripping spring on the fixed steel loop of balance away from rotor side.Improve the stabilization of motor operation
Property, while braking effect is improved, and the effectively structure such as protection rotor, reduce damage.
