產品詳情
Motor brake unit, AR9021
Warning
If a load is to be held even during standstill periods of a motor, a mechanical holding brake must be provided.
DC Brake Modules
A powerbrake unit is used where fast, efficient and predictable stopping of a machine in the shortest possible time is required. Using the d.c. injection method, it provides a controlled deceleration to a stop, by injecting a d.c. current into two of the motor terminals and neutralising the rotating magnetic field in the motor after the 3 phase supply has been disconnected. This stops the motor coasting to a halt and reduces the delay time by this enforced braking. They can be used with a standard 3 phase induction motor. The unit may be located on a piece of machinery or adjacent to it, with little disruption or modification required to the existing wiring. The Powerbrake units provide a simple cost-effective solution to motor braking, which is maintenance and wear-free.,Brake Module - For a brake unit, all the control wiring has to be supplied and installed by the customer, including interlocked contactors and pushbuttons.,Production Brakes - Enclosed brakes with all control wiring included, optional DOL starter built in Injects DC on EVERY stop.,Critical Brake - Enclosed brake with contactors built in. Must be used with existing starter, also AC must pass through the unit so that it can be isolated before DC is injected. Only injects DC when E-stop activated.
