Product Description:

The MKE037B-144-CG0-BENN is a servo motor manufactured by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for motion tasks in industrial automation systems located in potentially explosive areas, supplying position and speed control to connected machinery. The motor integrates an optical multiturn Hiperface encoder so the drive controller can track absolute shaft position throughout extended duty cycles. Because the encoder retains position information across multiple revolutions, the drive can restore axis location after normal power cycling without a new homing move. That feedback arrangement supports synchronized motion on indexing, transfer, and positioning axes where the controller must compare commanded and actual shaft angle continuously.

The motor housing meets ATEX requirements, allowing installation in zones where an ignition-capable surface must be avoided. Its exterior achieves an ingress protection rating of IP 65, so dust-tight protection and resistance to low-pressure water jets are maintained during washdowns. Thermal limits are set for ambient air between 0 to +40 °C, and the insulation system is rated 155 (F) for winding heat resistance. Position granularity comes from an encoder that delivers 128 increments per revolution, giving the controller fine motion resolution while still providing absolute feedback. These operating limits help the motor remain suitable for enclosed machine areas where airflow can be restricted by guards or sealed covers.

Electrical connections exit on the B-side through a terminal box, which supports protected cable entry in hazardous locations. The mechanical output uses a plain shaft with a frontal centering hole and a shaft seal, and the shaft uses a DIN 332 DS thread so pulling or mounting tools can be attached securely. The motor is supplied without a holding brake, so static load retention must be provided by the drive or by external clamps. Using a terminal box and a sealed shaft end also helps keep contaminants away from internal electrical and bearing components during routine machine operation. This layout supports repeatable coupling alignment while keeping the shaft end suitable for enclosed industrial service.
