Product Description:

The MKE037B-144-AG1-BUNN is produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Classified as a servo motor for hazardous areas, it supplies regulated torque and speed to machinery that operates where ignition control is critical. Integrated optical feedback supports closed-loop positioning, so motion controllers can keep conveyors, mixers, or filling modules at their commanded positions during normal operation. This makes the motor suitable for applications that need accurate motion together with protective design features for demanding industrial environments.

A permissible operating range of 0 to +40 °C sets the ambient temperature range for normal operation of the winding code 144 stator. Power and feedback conductors exit on the B-side through a terminal box, which supports orderly cable routing in explosion-rated enclosures. The housing is sealed to IP65, helping prevent dust and low-pressure water from reaching internal components. Internally, class 155 (F) insulation allows the windings to withstand elevated operating temperatures, and the construction meets UL/CSA requirements for North American installations. A permanent shaft seal helps block vapor ingress, and the plain front face uses a machined locating hole that helps align the motor accurately during mounting.

A spring-applied holding brake locks the rotor when power is removed, which helps prevent unintended movement on vertical or suspended loads. The output uses a plain shaft with a DIN 332-compliant DS thread at the tip for puller tools, and it also includes a single-lip seal to retain grease. Position data comes from a single-turn Hiperface optical encoder that provides 128 discrete increments per revolution under the S1 encoder model. This feedback arrangement supports repeatable position monitoring, while the brake helps keep the axis stationary during shutdown or power loss. The shaft and encoder layout also support routine coupling and controlled motion in enclosed industrial equipment.
