Product Description:
The MKE037B-144-CP1-BUNN is a servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Intended for use in potentially explosive industrial zones, it provides controlled rotary motion for positioning and speed regulation tasks in automated machinery and process equipment where dependable axis response is required. Construction complies with UL/CSA rules for electrical equipment in hazardous locations, which supports acceptance in North American installations.
Its enclosure carries an ingress rating of IP 65, meaning it is dust-tight and protected against low-pressure water jets, so additional cabinet sealing is seldom required. The specified ambient operating window of 0 to +40 °C lets the motor run in typical plant climates without derating. Power and feedback conductors are routed through a terminal box, which simplifies hard-wired field connections and helps keep external wiring organized near the motor. The winding code 144 is paired with an optical multi-turn absolute Hiperface encoder that delivers 128 counts per revolution, providing position data to the drive across repeated cycles and power interruptions. All electrical exits are on the B-side of the housing, allowing cable runs to be routed away from moving parts and crowded machine sections.
The motor includes a factory-installed holding brake assembly that clamps the rotor when power is removed, helping prevent drift on vertical axes during service pauses. Thermal endurance is supported by insulation class 155 (F), so the winding system can tolerate elevated internal temperatures during short overloads. A shaft machined to the DIN 6885 keyway standard and backed by a dedicated shaft seal provides a positive mechanical interface while helping block oil ingress at the drive end.
