Product Description:

The MKE118D-035-PG3-KUN servo motor is produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Designed for hazardous areas, the unit provides position and speed control for material-handling, mixing, and filling equipment installed in explosive environments. It operates at ambient temperatures from 0 to +40 °C and meets UL/CSA housing standards. All power and feedback conductors exit through a terminal box mounted on top of the frame, and the motor uses a plain shaft with a front centering hole, a DIN 332 "DS" thread, and an integral shaft seal for coupling to driven machinery.

At standstill, the motor can supply a continuous torque of 48.0 Nm while drawing 29.8 A. These values correspond to a 60 K winding rise and the 035 winding code, whose 0.210 Ω resistance and 3.20 mH inductance affect copper loss and current response. During acceleration, the inverter may demand up to 134.3 A to obtain a peak torque of 187.0 Nm, and the 0.03620 kg·m² rotor inertia influences how quickly that torque produces motion. A maximum speed of 3000 rpm is permitted, and the motor housing is sealed to IP65 to resist dust and water jets. A 70 Nm holding brake secures the load when power is removed, and additional data include a discharge capacity of 20.2 nF, insulation class 155 F, top-mounted connections, and a sound pressure level of 61.1 dB(A) ±3.

The motor has a torque constant of 1.87 Nm/A, which provides predictable torque per ampere. Its back-EMF constant of 114.5 V/min⁻¹ matches common 600 V class inverters. The cast-iron frame weighs 65.0 kg without the brake, adding mass that helps damp vibration and support stable operation. When paired with compatible Bosch Rexroth control hardware, the motor supports precise position and speed regulation in hazardous-duty production lines.
