Product Description:

The MKE118B-024-DP1-KE6 servo motor is produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Designed for use in potentially explosive areas, it converts electrical energy into controlled mechanical rotation for pumps, mixers, conveyors, and other motion axes that operate in hazardous gas or dust environments. Its ATEX-compliant housing allows direct installation in zone-rated locations and lets the motor be mounted close to the process while maintaining required safety clearances.

At standstill, the motor delivers a continuous torque of 28.0 Nm and draws a continuous current of 15.3 A with a 60 K winding temperature rise. A torque constant of 2.12 Nm/A lets the drive estimate torque from current for closed-loop control. Overload capacity includes a maximum torque of 102.0 Nm and a peak current limit of 69.1 A. Winding code 024 is paired with an inductance of 0.580 mH and a resistance of 7.60 Ω at 20 °C, which affect ripple and drive sizing. The voltage constant is 130 V/1000 rpm, and F-class insulation rated to 155 °C supports thermal durability. Position feedback comes from an M2 optical multi-turn EnDat 2.1 encoder with 2,048 increments per revolution.

The motor reaches a rated speed of 4000 rpm, and its rotor moment of inertia of 0.01940 kgm² helps moderate acceleration so the shaft with a DIN 6885 keyway can transmit load with reduced torsional oscillation. A holding brake provides 32 Nm of static torque to secure vertical loads during power loss, and shaft sealing helps prevent ingress at the shaft interface. Operation is permitted from 0 to +40 °C, and use above this range requires derating. Top-mounted terminal-box connections accept 17.0 to 19.5 mm cable glands, and a discharge capacitance of 10.3 nF supports electromagnetic compatibility. Sound pressure is 61.1 dB(A), the weight without the brake is 45 kg, and ATEX compliance supports use in explosive atmospheres.
