Product Description:
The MKE118D-012-AP0-KE6 is a servo motor for potentially explosive areas in the MKE Synchronous Motors series. Its ATEX-compliant housing and IP65 sealing allow use in hazardous zones where dust protection and resistance to low-pressure water jets are required. A top-mounted terminal box simplifies wiring, and the cable entry accepts glands from 17.0 mm to 19.5 mm. Operation is permitted from 0 °C to +40 °C, and Class F insulation supports the thermal load of the windings. The motor comes without a holding brake, so any static load must be held by external mechanics or drive-controlled torque.
At standstill with a 60 K winding temperature rise, the motor delivers 48.0 Nm continuously while drawing 13.0 A. For short, rapid indexing moves, it can handle 58.5 A RMS and produce a maximum torque of 187.0 Nm. The maximum speed is 2000 rpm, and the 012 winding has an inductance of 15.000 mH with a resistance of 0.98 Ω at 20 °C. The discharge capacitance is 20.2 nF, which helps limit high-frequency leakage toward the inverter. Position feedback is provided by an optical single-turn Hiperface encoder, model S1, with 128 increments, allowing the connected drive to track rotor position for controlled motion. Sound pressure is 61.1 dB(A) ±3.
The motor has a torque constant of 4.29 Nm/A and a back-EMF constant of 263.5 V/1000 rpm, values used to match current demand and voltage behavior with the drive. Dynamic response is supported by a rotor inertia of 0.03620 kg m², which influences acceleration and deceleration under changing loads. Total motor mass is 65.0 kg, and the shaft seal helps prevent lubricant loss and contaminant entry during operation. Torque is transmitted through a keyed shaft that conforms to DIN 6885. Shield terminations inside the enclosure help reduce conducted emissions to nearby equipment.
