Product Description:

The MKE047B-144-CG0-LUNN is a synchronous servo motor built by Bosch Rexroth Indramat for the MKE Synchronous Motors series. Designed for potentially explosive areas, it converts controlled electrical power into rotary motion for positioning and speed-regulated axes in automated machinery. When used in an intrinsically safe drive system, the motor provides the torque and feedback needed for closed-loop control without introducing ignition sources. This arrangement supports stable motion on equipment that must operate in hazardous locations.

The stator uses winding code 144, which gives the motor the electrical characteristics expected by the connected inverter. A rotor with 4 pole pairs links mechanical speed to drive frequency and supports lower base speeds with solid torque density. Position data comes from an encoder with 128 increments per revolution, and electronic interpolation refines angle and velocity calculation for the control loop. The sensing hardware is an optical multi-turn Hiperface encoder, so absolute position remains available across multiple turns after a power interruption. This motor is equipped with the M1 encoder version for this frame size.

The motor has a UL/CSA-compliant housing, which supports installation in North American hazardous locations where local approvals are required. Thermal endurance is supported by Class 155 (F) insulation, allowing the winding system to operate at elevated temperatures during continuous duty. Field wiring enters through a left-side terminal box connection, keeping cable routing clear of the shaft. Output torque is transmitted through a cylindrical shaft with a frontal centering hole, a fitted shaft seal, and a DIN 332 "DS" thread for puller or alignment tools. The motor is supplied with no holding brake, so the load must be secured by external locking or drive torque when power is off.
