Product Description:
The MKE118D-035-CP3-KUN is a three-phase synchronous servo motor produced by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Classified as a servo motor for potentially explosive areas, it supplies regulated mechanical power to material-handling and process equipment operating inside hazardous zones. The design allows automation controllers to issue precise torque and speed commands while the motor maintains compliance with UL and CSA safety listings for ignition-protected machinery.
At standstill, the motor produces a continuous torque of 48.0 Nm from a continuous current of 29.8 A measured at a 60 K copper temperature rise. For acceleration reserves, the drive may reach a peak torque of 187.0 Nm while sourcing up to 134.3 A RMS. A top speed of 3000 rpm pairs with a voltage constant of 114.5 V per 1000 rpm and a torque constant of 1.87 Nm/A, supporting predictable current-controlled operation. Winding code 035 corresponds to 0.210 Ω resistance, 3.20 mH inductance, and 20.2 nF discharge capacitance, which shape the electrical response. Rotor inertia is 0.03620 kg·m², and feedback comes from an M1 optical multiturn absolute Hiperface encoder with 128 increments per revolution. Power and feedback cables enter through a terminal box on top of the housing.
The integrated brake holds loads with 70 Nm of static torque, and the enclosure has an IP 65 rating. Safe operation is specified between 0 to +40 °C, while the Class F insulation system, shaft seal, and housing support this temperature range. A shaft with keyway made to DIN 6885 transmits torque reliably to the driven load. Operating sound pressure is 61.1 dB[A], which helps keep acoustic output moderate in occupied work areas. The motor’s unbraked mass of 65.0 kg affects lifting requirements and base-plate rigidity during installation.
