Product Description:

The MKE037B-144-KG0-LUNN is a flameproof AC servo motor manufactured by Bosch Rexroth Indramat as part of the MKE Synchronous Motors series. It serves as the electromechanical interface between an inverter and machinery in potentially explosive process areas, supplying controlled torque for positioning valves, dosing equipment, and handling devices in chemical or food production lines. Because it is a synchronous servo motor, the unit supports precise speed and position control when paired with a compatible drive. The design supports accurate motion control while meeting ignition-protection requirements for enclosed processing equipment.

It carries an enclosure protection level of IP 65, so dust is kept out and heavy water jets cannot reach live parts during operation. Continuous duty is permitted within an ambient range of 0...+40 °C, and operation outside that range requires derating. All power and feedback conductors exit on the left side through a cast-on terminal box, which helps organize cable routing inside wall-mounted barrier glands. This arrangement keeps the electrical connections grouped in one location and supports clean cable entry at the machine boundary. The stator winding uses class 155 (F) insulation, and compliance with UL/CSA construction rules supports installation in North American hazardous-location panels without additional field evaluation.

The motor uses a plain shaft with a machined DIN 332-compliant DS thread and a frontal centering recess for coupling alignment during assembly. The centered shaft end supports direct attachment to driven components that need repeatable positioning. Its stator uses winding code 144, which sets the electromotive constant for the intended torque-speed range. A shaft seal is already fitted at the output, which helps limit the entry of moisture and contaminants during washdown service. The motor is supplied without a holding brake, so external holding force is required when the axis must remain fixed at standstill.
