Fail safe disc brakes working on 24 V.D.C. also these brakes in other voltages i.e. 42,190 etc. In working they are more or less as per A.C. Disk Brakes only. Advantage of D.C. Brake over A.C. Brake is that they are compact in size. They being D.C. are sluggish in action and hence when continuous inching operations are there these brakes cause load on the motor. Hence they are ideal when number of operations are many but inching is not required. A.C. Brakes are not suitable when number of operations are very high but they can withstand if inching operations are made for small time or intermittently. |
