Product Description:

The MKE037B-144-KP1-BUNN is a three-phase servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for potentially explosive areas, where it supplies controlled torque and speed to actuators operating in hazardous zones that may contain flammable gases or dust. This makes it suitable for motion tasks in process plants, paint lines, and similar installations that require regulated axis movement. Its synchronous servo design supports precise response to drive commands during positioning and speed-controlled operation. The motor is used where motion control must be integrated without introducing separate ignition risks from the drive element itself.

The motor enclosure carries an IP 65 rating, so the housing resists dust ingress and low-pressure water jets. Internal windings use Class 155 (F) insulation to withstand elevated copper temperatures during cyclic duty. Power and feedback conductors terminate in a rigid terminal box, which simplifies armored conduit entry in explosion-protected installations. External surfaces and connectors conform to UL/CSA construction rules, which supports use on North American production sites. The output shaft supports positive torque transfer to couplings or gear stages. This arrangement suits servo applications that require stable mechanical engagement during repeated starts and stops. The 144 winding code matches the motor to standard IndraDrive inverters.

Cabling leaves the housing on the B-side, keeping the opposite face clear for mounting brackets in tight machine frames. Routing the cables from one side can also help when the motor is mounted close to guarding or nearby process equipment. Continuous service is permitted when ambient air remains between 0 to +40 °C, which suits typical indoor production floors. A factory-installed holding brake secures vertical or suspended axes when power is removed. The shaft uses a DIN 6885 keyway, which supports interchangeability with standard hub components. A shaft seal helps keep vapor or fine particulate from migrating along the journal into the bearing cavity, which helps protect the bearing area and lubricant.
