Product Description:
The MKE037B-144-CP0-BUNN is a three-phase synchronous servo motor manufactured by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for position and speed control in automated machinery located in potentially explosive process areas. By combining a compact rotor with an absolute optical encoder, the unit supplies closed-loop feedback to IndraDrive controllers, enabling precise axis regulation without external sensors. The motor’s keyed shaft transfers torque directly to gearboxes, linear stages, or pump couplings used in chemical, paint, and refinery production lines.
The enclosure is rated IP65, so dust ingress is prevented and the stator can withstand water jets during cleaning. Electrical insulation follows class 155 (F), permitting continuous winding temperatures up to 155 °C before thermal derating. The cast-iron housing meets UL/CSA standards, which simplifies acceptance in North American hazardous-location panels. Motion feedback originates from an M1 optical multiturn Hiperface encoder that delivers 128 discrete counts per revolution. The drive multiplies these encoder increments internally to obtain finer resolution for servo loops.
The motor operates within an ambient range of 0 to +40 °C, matching typical indoor production cells without auxiliary cooling. Power and feedback leads exit on the B-side and terminate inside a flameproof terminal box that supports armored conduit entry for hazardous zones. Stator copper is wound to code 144, which corresponds to the voltage and current relationship expected by matching drive inverters. Mechanical retention relies on drive torque alone because the unit is supplied without a holding brake. A shaft seal is fitted to block oil or solvent spray from reaching the front bearing, which helps protect the bearing area in paint booths and solvent mixers.
