Product Description:

The MKE037B-144-GP0-BUNN servo motor is produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. It is intended for closed-loop motion tasks in automated production cells, where precise torque and speed control are required to move tooling, conveyors, or actuators. The unit is suited for machinery installed in areas that may contain flammable gas or combustible dust, including equipment used in chemical processing, coating, and material-handling lines. This application focus makes the motor suitable for processes where controlled motion and protected construction must be combined in the same drive package.

Operation is permitted at ambient temperatures from 0 to +40 °C, so excess heat around the machine must be controlled during use. The housing has an IP65 rating, which helps protect internal parts from dust and low-pressure water jets. Compliance with UL/CSA requirements confirms that the motor meets North American safety rules for ordinary and classified locations. Power and feedback conductors terminate inside a terminal box, which supports organized cable entry and secure field connections. The motor is supplied without a holding brake, so axes that must remain fixed during power loss need an external holding method. Its winding code is 144, which indicates the electrical winding arrangement used for current control and thermal behavior.

The unit is described as a servo motor for potentially explosive areas, so it can be applied where ignition protection is required by the machine design. The insulation system is rated 155 (F), allowing the windings to operate at elevated temperatures within the motor's thermal class. All cables exit on the B-side, which can simplify routing when the flange faces the driven load and conduit space is limited on the opposite end. Torque is transferred through a shaft with keyway machined to DIN 6885, and the installed shaft seal helps limit the entry of dust or process fluids at the shaft interface. This combination supports secure power transmission to couplings, pulleys, or gear inputs used in enclosed industrial equipment.
