The HLR01.1N-66K0-N02R1-B-007-NNNNbrakeresistor is an essential industrial machine component produced by Rexroth Indramat to help in the dynamic braking of servo motors. During motor braking or deceleration, the servomotor acts as an electrical generator. It creates a large amount of electrical voltage, most of which is sent back to the drive controller through the power cable. The HLR01.1N-66K0-N02R1-B-007-NNNN brake resistor prevents the returned electrical voltage from damaging the servo drive by consuming the excess electrical voltage. The energy the resistor consumes is turned into heat energy and sent away from the resistor. The absence of the HLR01.1N-66K0-N02R1-B-007-NNNN brake resistor can lead to a steady increase in the drive controller's circuit voltage until the power circuits snap, leading to a machine brake down.
The braking resistor is perfect for the HCSO3 and HCSO2 servo drive series as they can be mounted above these servo drives and can be cooled by the exhaust air emitted by these servo drive series. The HLR01.1N-66K0-N02R1-B-007-NNNN Brake resistor is generally more useful in applications that require fast deceleration during operation; such applications include conveyors, lifts, electrical locomotives, trolly buses, etc.
The HLR01.1N-66K0-N02R1-B-007-NNNN brake resistor has a continuous braking power of 66 kilowatts. It is designed with an ohmic resistance of about 2.1 Ohms. During normal operation, the brake resistor can consume a regenerated current of over 2000 Kilowatts. The brake resistor has a minimum allowed cycle time of about 120 seconds. The brake resistor's housing is designed according to the IP 20 protection category; it protects the resistor from damage, increases its service life, reduces the need for constant service and repair, and gives room for easier and more effective installation techniques. This brake resistor can be shipped globally with a one-year warranty period from Wake Industrial.
