Product Description:

The MKE037B-144-CP0-AUNN is a servo motor engineered by Bosch Rexroth Indramat within the MKE Synchronous Motors series. As a servo motor for potentially explosive areas, it converts drive commands from certified controllers into precise rotary motion without creating ignition sources. The model’s sealed housing and conformity with North American safety listings allow it to drive actuators, mixers, or positioning stages installed in hazardous industrial zones where combustible gases or dust may be present.

The motor has clear environmental and electrical limits. It is rated for ambient temperatures from 0…+40 °C, ensuring continuous torque delivery in typical enclosure climates. All power and feedback leads exit through a terminal box on the A-side, so the conduit run can be oriented toward the feed-through panel. The enclosure carries an IP65 ingress rating that blocks dust and water jets, while the housing meets UL/CSA construction requirements for North American installations. The internal insulation is rated at 155 (F), allowing the stator windings to tolerate elevated operating temperatures before thermal derating. A shaft seal is fitted, and the motor has no holding brake, so the load must be secured externally when power is removed.

Position feedback is supplied by an optical multiturn encoder that delivers 128 increments per mechanical revolution, supporting tight velocity loops in explosion-protected motion systems. The output shaft uses a DIN 6885 Keyway, ensuring that the coupling can transmit torque without slipping. Coil set code 144 corresponds to the electrical winding and the current constant expected by the compatible drive. Encoder variant M1 combines multiturn capability with the Hiperface protocol, allowing absolute position retrieval after power recovery. This arrangement supports accurate speed control and repeatable position tracking during closed-loop servo operation.
