Product Description:
The MKE118B-024-AG0-KE4 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Designed for potentially explosive areas, the motor provides rotational power to position-controlled axes in chemical, paint, and refinery automation lines where certified electrical equipment is required. Its ATEX-compliant housing, plain shaft with a frontal centering bore, and top-mounted terminal box support secure, low-maintenance installation inside flameproof enclosures. The flameproof design is suited to areas where ignitable gases or vapors may be present during normal plant operation.
The motor reaches a top speed of 4000 rpm, allowing direct coupling to gear stages or lead screws without overspeeding the rotor. Under a 60 K winding temperature rise, it delivers a continuous stall torque of 28.0 Nm while drawing 15.3 A, and it can withstand short-term load peaks up to 102.0 Nm when the RMS phase current climbs toward 69.1 A. The electromagnetic design develops torque in proportion to current with a constant of 2.12 Nm/A, so each additional ampere produces a predictable increase in shaft torque. This linear torque behavior helps the drive respond consistently during acceleration, holding, and speed changes. The winding code is 024, with 0.580 mH inductance and 7.60 Ω resistance, so the drive must regulate the motor with the appropriate current response.
The motor operates within an ambient range of 0 to +40 °C without derating, and its Class F insulation is rated for winding temperatures up to 155 °C. A steel stator and laminated rotor give the assembly a mass of 45.0 kg, while the rotor inertia is limited to 0.01940 kg m² to support responsive acceleration. Single-turn Hiperface optical encoder feedback provides 128 increments per revolution, and the encoder signal allows the drive to track rotor position during closed-loop motion control. An integral shaft seal is fitted, the motor comes without a holding brake, and the listed sound level is 61 dB[A].
