Product Description:

Bosch Rexroth Indramat manufactures the MKE037B-144-AP0-BENN in its MKE Synchronous Motors series. This model is a servo motor for potentially explosive areas and is designed to deliver controlled torque and speed inside automation zones where combustible dust or gas may be present. The housing follows ATEX rules, allowing the motor to integrate into certified drive packages on conveyors, mixers, or positioning axes that operate under hazardous classifications. When paired with coordinated drives, the unit converts electrical input into precise mechanical motion for process equipment.

Environmental protection is provided by the IP 65 enclosure, which seals the stator frame against dust ingress and water jets. The housing also meets ATEX requirements so that surface temperatures stay below ignition limits during rated operation. Electrical power and feedback lines enter through a terminal box, and these connections are oriented on the B-side of the motor to simplify routing in tight machine frames. Continuous operation is permitted within an ambient range of 0 to +40 °C, and the F-class insulation system supports winding temperatures associated with that climate window. The 144 winding code supports standard inverter voltages in this power class.

The position loop is closed by an optical encoder that uses the single-turn Hiperface protocol, and the S1 model supplies 128 increments per revolution for moderate resolution in speed and positioning tasks. Because there is no holding brake, the drive must supply torque when standstill retention is required. The windings use insulation class 155 (F), enabling full duty without thermal derating when the motor is driven at its nominal current. Mechanical linkage is handled by a shaft with a keyway, machined to DIN 6885 and protected by a shaft seal that helps keep oil or dust out of the bearing chamber.
