Product Description:

Bosch Rexroth Indramat manufactures the MKE037B-144-CG0-BUNN as part of the MKE Synchronous Motors series. Classified as a servo motor for potentially explosive areas, the unit supplies controlled rotary motion in mixers, filling machines, and material-handling stations that must comply with strict ignition-prevention rules. A plain shaft with a frontal centering hole simplifies coupling to drive trains, and the 144 winding matches the electrical characteristics used with standard IndraDrive amplifiers for precise speed and position control.

The motor uses an IP 65 enclosure that prevents dust ingress and guards against low-pressure water jets, so the housing can be cleaned in place. The cast housing also carries the UL/CSA marking, confirming acceptable clearance, creepage, and thermal limits for North American installations. Power and feedback conductors are routed through a terminal box mounted on the B-side, which keeps cable glands away from process areas and improves access in tight installations. Continuous operation is permitted within an ambient temperature range of 0 to +40 °C, and a shaft seal helps block oil migration from the gearhead into the bearing and encoder cavities.

The internal sensing system uses an multi-turn absolute Hiperface optical encoder in model M1, delivering position data across 4096 turns while issuing 128 increments per revolution for drive interpolation. Thermal endurance is supported by insulation class 155 (F), allowing winding temperatures up to 155 °C without varnish breakdown. Motion is transmitted through a shaft that carries a DIN 332-compliant DS thread, and the frontal centering hole helps speed alignment during assembly. The motor is supplied without a holding brake, so vertical axes must rely on an external mechanical lock for static holding torque.
