Product Description:
The MKE037B-144-AG0-BUNN is a servo motor produced by Bosch Rexroth Indramat as part of the MKE Synchronous Motors series. Intended for motion control in potentially explosive areas, it supplies regulated torque and speed to machinery where ignition-rated equipment is required in industrial automation. Its synchronous design helps the connected drive maintain accurate speed and position under changing load conditions.
The cast-aluminum housing carries an IP 65 rating, sealing the interior against dust and water spray commonly found on plant floors. Safe operation is permitted at ambient temperatures from 0 to +40 °C, so the surrounding air must remain within this range during use. Power and feedback conductors exit on the B-side, allowing right-angle cable routing when the motor is flange mounted. A sealed terminal box hosts the field connections, providing screw terminals for straightforward wiring in classified zones. The stator uses winding code 144, which indicates the motor's voltage constant and the current profile expected by compatible drive inverters. A shaft seal prevents oil or dust from entering along the plain shaft while still permitting full-speed rotation.
Position feedback is delivered by an optical single-turn Hiperface encoder that offers 128 increments per revolution and is identified by model S1. Class F insulation, rated at 155 (F), allows the winding temperature to rise without premature varnish degradation during cyclic overloads. The housing and wiring practices meet UL/CSA requirements for North American hazardous locations. There is no holding brake, so axial loads must be secured by external means during power loss. A plain steel shaft with a frontal centering hole and a DIN 332-compliant DS thread supports keyless couplings and helps with alignment during assembly.
