Product Description:

The MKE047B-144-CP0-BE0N is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is built for drive tasks in potentially explosive industrial zones where accurate torque and speed regulation are essential for conveyor sections, mixers, or positioning tables. When paired with an appropriate inverter, the motor converts electrical input into controlled rotary motion while meeting hazardous-area safety demands. This makes it suitable for process equipment that must maintain repeatable motion during normal production.

The motor uses winding code 144, which sets the voltage constant and continuous current values used during drive selection. A rotor with 4 pole pairs establishes the electrical frequency relationship, allowing the controller to generate synchronous torque over a wide speed range. Class 155 (F) insulation protects the windings at elevated operating temperatures. Feedback comes from an optical multiturn absolute Hiperface encoder that returns unique position data across 4096 mechanical revolutions, enabling homing-free startup after power is applied. Within each revolution, the encoder supplies 128 increments, giving the control loop sufficient resolution for fine velocity and position regulation.

An ATEX housing prevents hot surfaces or sparks from igniting ambient gases, so the motor can be mounted directly in Zone 1 applications. Power and signal leads terminate in a sealed terminal box, which simplifies armored cable entry while maintaining enclosure integrity. For cabinet orientation, the cables exit on the B-side, which helps keep bends short and reduce strain. Output torque is transmitted through a shaft with a DIN 6885 keyway, allowing standard keyed couplings to mate without additional machining. A shaft seal keeps lubricants inside the bearing cavity and blocks dust or vapors from entering the motor interior.
