Product Description:

The MKE118D-012-AG0-KE4 is a servo motor developed by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Designed for potentially explosive areas, it uses an ATEX-compliant housing and an IP65 enclosure rating, so the stator and internal electronics remain isolated from dust and water jets. Within industrial automation cells, it converts drive current into precise rotary motion for controlled positioning of pumps, mixers, or indexing tables used in chemical or paint facilities where ignition sources must be minimized.

At standstill, the motor can deliver a continuous torque of 48.0 Nm while the windings remain 60 K above ambient. To sustain that output, the motor draws a continuous current of 13.0 A from the drive. When rapid acceleration is required, the electromagnetic system can deliver up to 187.0 Nm before thermal limits intervene, and the rotor can reach a mechanical speed of 2000 rpm. A top-mounted terminal box simplifies routing through 13 to 16 mm cable glands, and the connection direction is upward to keep conductors clear of washdown surfaces. Operation is permitted between 0 °C and +40 °C without derating.

The electrical constants describe how the drive regulates flux and heat during operation. Each ampere supplied produces 4.29 Nm/A, so current commands can be scaled directly to motion demands. Back EMF rises at 263.5 V/rpm, which helps determine the required DC bus voltage and regenerative hardware. The winding inductance of 15.000 mH and resistance of 0.98 ohm shape current-loop response and loss behavior, while a rotor inertia of 0.03620 kgm² balances dynamic response with load damping. The S1 optical encoder provides 128 increments, a shaft seal helps prevent lubricant leakage, and the 65 kg housing ends in a plain shaft with a DIN 332 "DS" thread for secure coupling.
