Product Description:

The Bosch Rexroth Indramat MKE118D-027-CG0-KE4 belongs to the MKE Synchronous Motors series and is specified as a servo motor for potentially explosive areas. Within an automated production cell, it translates drive controller commands into regulated shaft rotation for positioning tasks that must remain safe where flammable gases or dust are present. The unit’s mechanical format permits mounting on heavy conveyor or machine axes that demand high continuous torque.

Electrical performance begins with a continuous stall torque of 48.0 Nm produced at a standstill current of 22.1 A when the windings are at 60 K. The same windings, code 027, show 5.70 mH of inductivity and 0.350 Ω of resistance, while their discharge capacity is 20.2 nF. During acceleration the drive may deliver 99.6 A to reach a peak torque of 187.0 Nm, and the rotor can be spun up to 3000 min⁻¹. Dynamic behavior benefits from a 0.03620 kg·m² moment of inertia. Position feedback comes from an optical multiturn absolute Hiperface encoder, model M1, with 128 increments per revolution. Power and feedback conductors enter through a top-mounted terminal box that accepts 13.0 mm to 16.0 mm cable glands, simplifying cabinet routing.

Environmental suitability is defined by IP 65 sealing, an ATEX housing standard, and continuous operation between 0 °C and +40 °C. There is a plain shaft with a frontal centering hole, a DIN 332 “DS” thread, and a shaft seal to limit lubricant egress. The motor is supplied without a holding brake, weighs 65.0 kg, and emits 61.1 dB(A) ± 3 during nominal load. A torque constant of 2.52 Nm/A supports finely metered motion, while the back-EMF constant of 154.5 V/1000 min⁻¹ helps the controller predict speed. Class 155(F) insulation withstands thermal stresses, and the design completes the high-inertia axis introduced above.
