Product Description:

The Bosch Rexroth Indramat MKE047B-144-CP0-RUNN is a synchronous servo motor in the MKE Synchronous Motors series. Classified as a servo motor for potentially explosive areas, it connects to Rexroth drives to produce controlled rotary power where flammable atmospheres can occur. This type of motor is intended for applications such as mixers, valves, and conveyors that need accurate speed and position control in enclosed or process-oriented equipment. Its sealed housing is intended for hazardous locations, helping limit exposure of internal ignition sources to the surrounding atmosphere during normal operation.

The power interface is mounted on the right side inside a terminal box, directing conductors away from nearby process equipment and keeping the connections enclosed. A three-phase stator with winding code 144 generates the electromagnetic field for servo operation, and the integrated Optical encoder, Multiturn absolute Hiperface supplies position data with 128 absolute counts per turn. This feedback arrangement lets the paired drive monitor shaft position across multiple revolutions and support controlled motion after power-up. The motor is supplied without a holding brake, so any static load must be held by the machine mechanism or by drive-produced torque when the axis is stopped.

Encoder variant M1 stores multiturn position data and transmits it over the same feedback interface, reducing the need for separate sensing hardware. Compliance with UL/CSA requirements supports use in North American plants, and insulation class 155 (F) supports sustained winding temperatures during continuous duty. The magnetic design uses 4 pole pairs for smooth torque production across the operating range. The output shaft has a DIN 6885 keyway for positive torque transfer, and a shaft seal helps block vapor ingress at the drive end.
