Product Description:
The MKE037B-144-AP0-AUNN is a small-frame synchronous servo motor produced by Bosch Rexroth Indramat and supplied within the MKE Synchronous Motors series. It is engineered as a flameproof drive element for automation zones classified as potentially explosive, where it converts drive controller output into precisely regulated rotational motion. By pairing electrical commutation with an integrated optical feedback device, the unit delivers closed-loop position and speed control for valves, agitators, and compact pick-and-place axes that require consistent torque and low installed mass.
Rated operation is permitted in ambient temperatures from 0 to +40 °C, so enclosure cooling is unnecessary for typical indoor machinery halls. An ingress rating of IP65 confirms that the stator housing blocks dust and low-pressure water jets, allowing washdown without additional protection. The windings are insulated to class 155 (F), which supports continuous cyclic duty at elevated winding temperatures. Rotor position is digitized by 128 line pairs for commutation feedback. The motor is delivered without a holding brake, so external clamping or drive torque must secure the load after power-off.
The power and signal conductors enter through a terminal box that is oriented on the motor’s A-side, so the cables exit parallel to the mounting face. Feedback is generated by a single-turn Hiperface optical encoder, and its analog sinusoidal tracks are sampled by the drive to provide absolute shaft position after each startup. Mechanical energy is transferred through a keyed shaft that follows the DIN 6885 keyway profile, and a factory-installed shaft seal helps prevent lubricant leakage. The unit also conforms to UL and CSA requirements, and winding code 144 matches the motor to the intended drive current range.
