KFB series safety and service brake developed several years ago is mainly used in internally and externally ventilated motors of travelling, trolley and hoisting gear in crane installations or for industrial applications. An electric field is built up through the properties of the brake current and overcomes the spring tension of the brake is overcome. The corresponding sub-assemblies including the motor shaft can rotate freely.
During switch off of the brake current or power failure, the electromagnetic field of the brake collapses and the mechanical brake action is transferred to the motor shaft. The motor is applied with brake. The series features dynamic brake with braking torque of 100 to 1600Nm. The compact design offers high work capacity, high wear reserve and offers compatible mounting on every electric motor or gear. The optimum design of the series offers low maintenance cost and operation.
