Product Description:
The MKE118B-024-DP1-KE4 is a synchronous servo motor built by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for drives located in potentially explosive zones. In these applications, it converts electrical energy into controlled rotary motion for conveyors, mixers, and positioning axes that require certified ignition protection. Its synchronous design allows the connected drive to regulate torque and speed with precise motion control.
With a 60 K winding rise, the motor supplies a continuous standstill torque of 28.0 Nm while drawing 15.3 A. When acceleration peaks are required, the shaft can deliver up to 102.0 Nm and the power stage may momentarily source 69.1 A. Mechanical speed is capped at 4000 rpm, and each ampere of phase current produces 2.12 Nm/A of torque, so response remains linear over the working range. Winding code 024, together with 0.580 mH inductance and 7.60 Ω resistance, contributes to the electrical time constants, while a 10.3 nF discharge capacity aids common-mode filtering. Position feedback is supplied by an M2 optical multi-turn absolute EnDat 2.1 encoder with 2,048 increments, giving the controller fine position resolution. A 32 Nm holding brake helps prevent shaft movement during power loss, and the ATEX-compliant housing keeps ignition sources isolated.
The rotor inertia is 0.01940 kgm², which provides stable yet responsive behavior for medium-mass loads. Total mass without the brake is 45.0 kg, and Class F insulation rated for 155 °C withstands internal temperatures above the ambient range of 0 to +40 °C. A voltage constant of 130.0 V/min⁻¹ matches high-bus drives without excessive back EMF. Power and feedback leads enter through a 13–16 mm gland in the top-mounted terminal box, and a shaft with a DIN 6885 keyway plus a shaft seal allows direct coupling in oil-splashed gearboxes. The top connection orientation also simplifies cable routing inside flame-proof enclosures.
