Product Description:
The MKE118B-024-AP0-KUN is a servo motor manufactured by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for use in potentially explosive areas where controlled rotary motion is required. When paired with a matched converter, it provides precise torque and speed control for pumps, mixers, and positioning stages installed in hazardous zones. The motor is suited to applications that require stable motion and consistent response during regulated operation.
Power conductors are routed upward because the connection direction is at the top, and they terminate in a sealed terminal box built to UL/CSA housing standards. At standstill, the motor delivers 28.0 Nm while drawing 15.3 A, which corresponds to the continuous operating point for the 024 winding with a 60 K winding temperature rise. The 024 winding code identifies the electrical winding used in this frame size. The optical single-turn Hiperface encoder, model S1, supplies 128 increments to the drive for accurate commutation, and its 10.3 nF discharge capacitance helps protect the feedback channel against electrostatic pulses. A torque constant of 2.12 Nm/A gives the relationship between stator current and shaft torque, while the winding has an inductance of 0.580 mH and a resistance of 7.60 Ω. For short-duration demand, the stator can reach 69.1 A, and the rotor can run at up to 4000 rpm. Operation is quiet at 61.1 dB[A].
The motor has a mechanical torque limit of 102.0 Nm and a rotor inertia of 0.01940 kgm², which supports quick load reversals without excessive overshoot. Its laminated core uses Class F insulation, and the motor weighs 45.0 kg, adding thermal mass for sustained operation. A voltage constant of 130.0 V/min⁻¹ is used in back-EMF calculations, and safe operation is specified between 0...+40 °C. The DIN 6885 key-slotted shaft includes a shaft seal for enclosed operation. The motor does not include an internal holding brake.
