Product Description:

The MKE116B-058-NG1-KN is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MKE Synchronous Motors series. It serves as a drive element that translates the command signals of a digital controller into regulated mechanical motion for equipment used in automated production lines, material-handling systems, and process machines installed in potentially explosive zones. In closed-loop operation, the motor provides the rotary output needed for accurate positioning, stable speed control, and repeatable response to changing loads.

The power and feedback conductors are routed from the top of the housing, a connection direction that simplifies vertical cabinet layouts and helps maintain consistent bending radii. All terminations are made inside a sealed terminal box, allowing armored cables or conduit fittings to be attached without adapters. Winding code 058 indicates the motor’s phase resistance, inductance, and thermal limits, so the selected drive inverter can supply matching current without saturation. A plain shaft is used, so torque is transmitted by friction-fit couplings rather than keys, which helps reduce stress concentrations. For transport screws, tensioning devices, or alignment pins, the shaft end carries a DIN 332-compliant DS thread, making standardized hardware compatible with the rotor.

The motor is supplied with a holding brake, enabling the load to remain locked when power is removed and eliminating external clamping devices on vertical axes. For zones where ignition sources must be minimized, its classification as a servo motor for potentially explosive areas confirms that clearances, surface temperatures, and material choices follow the relevant safety directives. Precision mounting is aided by a frontal centering hole, which aligns the rotor to the driven element without shims. A shaft seal blocks oil mist, dust, and moisture from entering the bearing cavity, preserving lubricant life during long duty cycles.
