Product Description

The Rexroth MKD090B-047-KP2-KS is a synchronous AC motor. Integrated features available on the motor include holding brake and resolver feedback. Specifications for the holding brake are as follows: 18 Nm holding torque, 24 Volts DC rated voltage, 0.71 Amps rated current, 3.13 x 10^-4 kg m² moment of inertia, 16 milliseconds clamping delay and 90 milliseconds release delay. Feedback is provided through integrated multiturn absolute encoder. Shaft on the MKD090B-047-KP2-KS has key as per DIN 6885-1 and also includes sealing ring to provide protection against moisture and dust ingress. Housing of the MKD090B-047-KP2-KS is designed for ex type for cluster II category 3, G and D as per DIN EN 50021. Connections for the encoder and power input on the MKD090B-047-KP2-KS are located on a terminal box which is found on side B of the motor.

As per type code for Rexroth MKD motors, the motor size for the MKD090B-047-KP2-KS is 090, the winding code is 047 and the motor length is B. Speed-torque curves and technical data for MKD motors are specified for 60K housing overtemperature and 100K winding overtemperature. For the 60K characteristic curve, the motor data are determined using motors which have ambient temperature of around 45 degrees Celsius and allowed housing overtemperature of 60K. For the 100K characteristic curve, the motor data are determined using motors which have ambient temperature of around 40 degrees Celsius and allowed housing overtemperature of 100K. Rated speed for the MKD090B-047-KP2-KS is 3500 RPM for both types of overtemperature conditions. The rated toque for the MKD090B-047-KP2-KS is 6.2 Nm at 60K overtemperature and 9.9 Nm at 100K overtemperature. The rated power for the MKD090B-047-KP2-KS is 2.7 kilowatts at 60K overtemperature and 4.8 kilowatts at 100K overtemperature. This unit can be shipped globally with a one-year warranty period from Wake Industrial.
