This brake is a spring actuated type which makes brake action on the interruption of coil excitation. When exciting the coil, the field attracts armature beyond the sprig force, then it makes the gap between inner-disc and outer-disc and brake becomes free. When to interrupt the coil exciting, the field releases armature by spring force, and the brake is actuated. Autmatic braking is made when the power supply is shut off.
[Points]
As ESB has multipul discs, larger braking torque can be produced with its compacted body. |

Note:
1.The insuration level of our standard coil is E class (120°C).
2.The initial braking torque on delivery is 50~60% of the rated value and it increases after preperatory operations.
3.Standard shaft direction. is horizontal. Please refer to us for vertical use. |
