Product Description:

The MKE037B-144-CP0-BENN is a servo motor engineered by Bosch Rexroth Indramat for use in potentially explosive atmospheres. As a member of the MKE Synchronous Motors series, the unit combines flameproof construction with closed-loop feedback to drive rotary axes inside hazardous-area machines. In industrial automation, it converts electrical command currents into controlled torque for mixers, filling machines, or valve actuators positioned in zones where vapors or dust can ignite. The compact rotor-stator assembly inside the MKE037B-144-CP0-BENN delivers precise motion while meeting safety requirements for explosive environments.

The motor functions reliably from 0 to +40 °C, allowing installation in standard production halls without auxiliary climate control. Its cast-aluminum enclosure is sealed to IP65, blocking airborne dust and water jets that could interfere with bearings or windings. Certification under ATEX enables mounting in Zone 2 gas or Zone 22 dust areas when used with compliant connection hardware. Thermal endurance is supported by insulation class 155 (F), permitting winding temperatures up to 155 °C during intermittent overloads. Power, signal, and ground conductors are routed through a terminal box, simplifying armored conduit entry and maintaining the flame path required for hazardous-area wiring.

The stator uses winding code 144 to match drive inverters designed for low-current, high-voltage operation, and the laminated steel core is paired with a shaft that has a keyway for positive torque transfer to sprockets or couplings. For position feedback, an optical multiturn absolute Hiperface encoder delivers 128 increments per mechanical revolution and maintains a separate turn counter, enabling precise reference recovery after power loss. All cabling exits on the B-side, keeping service clearances consistent when several motors are mounted in line. Because the unit is supplied without a holding brake, stationary loads must be secured by drive torque or external clamping devices in vertical or safety-critical axes.
