Product Description:
The MKE037B-144-KG1-BENN is a servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. The unit converts electrical energy into controlled rotary motion for positioning valves, conveyors, or filling heads inside hazardous production cells. Its construction makes it suitable for industrial automation areas that require flameproof components while still needing the fast speed and torque response associated with synchronous servo technology. Because the motor is intended for controlled motion rather than simple constant-speed duty, it can be used where an axis must start, stop, and adjust speed in a repeatable way.
To meet enclosure and temperature safety targets, the motor carries an IP 65 rating, which protects the stator and bearings from dust ingress and low-pressure water jets. The housing is certified under ATEX, so it can be installed in gas or dust explosion zones without external purging systems. An insulation system classified as 155 (F) permits continuous winding temperatures up to 155 °C, which supports stable thermal performance during normal operation. The permitted ambient range of 0…+40 °C keeps the motor within its intended operating window. Power and feedback leads enter through a terminal box, allowing armored conduit to connect directly to the frame with secure strain relief and a protected cable entry path.
All cable connections are oriented toward the B-side of the frame, which helps reduce cable loops in tight machine spaces and keeps routing more organized around nearby hardware. The unit is supplied with a holding brake, so the shaft can remain locked during power loss instead of relying on a separate external clamping device. The output uses a plain shaft with a DIN 332-compliant DS thread at the face, and this arrangement supports accurate coupling to gearheads or load flanges during assembly. A shaft seal is fitted to protect the internal bearings, and the 144 winding designation matches the motor to compatible drive controllers through its electrical characteristics.
