Product Description:

The MKE047B-144-KP1-BENN is a synchronous servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Designed for potentially explosive areas, it supplies controlled rotary motion to conveyors, pick-and-place modules, and dosing heads in hazardous zones where ignition sources must be restricted. Integrated into a closed-loop drive system, the unit converts commanded current into precise torque and speed for accurate positioning. Its synchronous operating principle helps the connected drive maintain stable motion during frequent starts, stops, and load changes. Because the motor is intended for hazardous locations, it is suited to automated processes that must maintain motion accuracy without introducing exposed ignition risks.

Field wiring enters from the B-side, where a terminal box houses the power and feedback connections and supports rigid conduit routing. Locating the connection area on one side helps keep cable routing orderly when the motor is mounted in compact guards or enclosures. Compliance with ATEX construction requirements allows installation in areas that require certified protection against ignition hazards. The motor uses an insulation system rated 155 (F), which allows the stator windings to withstand elevated operating temperatures in compact machine spaces. The motor has 4 magnetic pole pairs, and this pole arrangement works with winding code 144 to support smooth synchronous operation on medium-inertia loads.

For holding functions, the integrated brake provides 2.2 Nm of torque when supply power is removed, which helps prevent load drift on vertical or safety-related axes. Mechanical output is transmitted through a shaft with a keyway that follows the DIN 6885 Keyway profile, allowing direct connection to standard hubs and couplings. A keyed shaft also supports positive torque transfer in applications that use pulleys, couplings, or geared attachments. The motor also has a shaft seal, which helps keep oil mist and fine dust away from internal components. The sealed drive end is useful in process machinery where airborne contaminants may be present around the motor.
