Product Description:
The MKE098B-047-DP1-BENN is a servo motor engineered by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Designed for use in potentially explosive areas, it supplies controlled rotary motion to actuators, conveyors, and positioning tables installed in hazardous industrial zones where flammable gases may be present. The motor combines an explosion-protected housing with coordinated feedback so drive controllers can maintain precise speed and torque loops in these automation environments.
The motor uses winding code 047 with a resistance of 8.400 Ω at 20 °C and an inductance of 1.20 mH. It supports a continuous phase current of 9.8 A when the frame temperature rise does not exceed 60 K, and under the same thermal condition it delivers 12.0 Nm of standstill torque. For acceleration peaks, the drive may apply up to 44.3 A RMS, raising shaft output to 43.5 Nm and allowing speeds up to 4500 rpm. The induced voltage at rated speed is 91.0 V per 1000 rpm, and operation is permitted from 0 °C to +40 °C ambient with Class F insulation rated for 155 °C winding temperatures. Electrical terminations are routed on the B-side through a sealed terminal box, which simplifies conduit entry while maintaining the motor's discharge capacity of 6.7 nF for EMC control.
Closed-loop control is handled by a multiturn optical EnDat 2.1 encoder, model M2, that offers 2,048 increments per revolution. Its data are referenced to a torque constant of 1.41 Nm/A for current vector calculations. Dynamic response benefits from a rotor inertia of 0.00430 kg m², and airborne noise is limited to 61.8 dB[A]. A factory-mounted holding brake rated at 11 Nm secures vertical loads when power is removed. The housing meets ATEX requirements and weighs 18.0 kg without the brake. A shaft with a DIN 6885 keyway and a positive shaft seal transmits torque while helping block oil or dust ingress.
