Product Description:

The MKE037B-144-KP0-BUNN is a servo motor manufactured by Bosch Rexroth Indramat and supplied in the MKE Synchronous Motors series. Designed for potentially explosive areas, the unit delivers controlled torque for valves, conveyors, or positioning axes that operate in chemical, pharmaceutical, or paint facilities. Its balanced magnetic circuit and integrated resolver feedback allow precise closed-loop motion when paired with a compatible drive controller, enabling automated sequences in production lines without relying on external pneumatic or hydraulic actuators.

The motor housing carries an IP65 ingress rating, so dust penetration is prevented and water jets cannot reach live parts during washdown cycles. Electrical termination is completed through a top-mounted terminal box, which simplifies conduit routing in hazardous zones. Continuous operation is allowed within an ambient range of 0 to +40 °C, and running the unit outside this window can shorten insulation life. The class-F winding insulation is rated at 155 °C, enabling the stator to handle elevated core temperatures without dielectric failure. For dynamic stopping, external mechanics must be used because the rotor is supplied without a holding brake, which reduces internal heat sources and minimizes inert particles inside the enclosure.

Mechanical integration favors service access on the cable side, and all power and feedback exits are oriented toward the B-side. The casting follows UL/CSA construction guidelines, allowing installation in North American classified locations when paired with approved glands. A nitrile shaft seal is fitted to block vapor ingress, while torque is transmitted through a shaft machined with a DIN 6885 keyway, ensuring repeatable coupling alignment. The electromagnetic layout uses winding code 144, which corresponds to the resistance and inductance values used by compatible drives in the MKE family.
