Product Description:

The MKE037B-144-CP0-BE0N is a servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for potentially explosive areas, so it delivers controlled torque and speed to machinery installed in hazardous zones where flammable gas or dust may be present. When paired with a compatible drive, the motor supports position-controlled rotary motion for conveying, mixing, and metering duties that require reliable operation in these environments. This arrangement lets the drive regulate motion accurately during startup, running, and stopping sequences in process equipment.

The housing carries an IP 65 rating, meaning the enclosure is dust-tight and resists water jets that could otherwise reach internal windings and bearings. Compliance with ATEX allows the motor to be installed in designated explosion-risk atmospheres, and an allowable ambient range of 0 to +40 °C helps prevent thermal stress during normal operation. The stator uses winding code 144, which indicates the electrical characteristics expected by the matching drive for stable current control. Rotor position feedback comes from an optical multiturn Hiperface encoder, model M1, that outputs 128 increments per revolution so the control loop retains fine angular resolution after a power cycle. That feedback format supports closed-loop positioning without requiring separate external sensing hardware at the axis.

Cabling exits on the B-side of the frame and terminates inside a sealed terminal box, which supports protected field wiring while maintaining the required enclosure integrity. Thermal endurance is supported by insulation class 155 F, allowing the winding system to tolerate elevated internal temperatures before insulation damage becomes likely. Mechanical power is transmitted through a shaft with a DIN 6885 keyway, providing a standardized connection for couplings that need positive torque transfer. The motor is supplied without a holding brake, so any static load must be held by the drive or by an external locking device. This makes the unit better suited to applications where the driven load does not require mechanical holding torque after power is removed.
