Product Description:
The MKE047B-144-GG0-BUNN is a servo motor produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Engineered for use in potentially explosive areas, it converts drive controller commands into controlled torque and speed for zone-classified pumps, mixers, or positioning axes. The design follows the manufacturer’s safety concept for hazardous locations while keeping the mechanical envelope identical to standard MKE units. That approach lets the motor fit machine layouts that already use the same frame format. It is intended for closed-loop motion tasks in process equipment where accurate rotary control and hazardous-area suitability are both required.
The power and feedback leads exit on the B-side, and a terminal box provides segregated chambers for intrinsically safe and power circuits. Class-F insulation rated at 155 (F) permits continuous winding temperatures suitable for variable-torque duty without premature aging. Four magnetic pole pairs create the synchronized field, and a count of 4 helps support stable torque delivery with useful speed bandwidth in a mid-frame motor. The 144 stator winding matches drive modules that supply the required current and voltage range. The motor is supplied without a holding brake, so the load must be secured by mechanical clamping or drive torque when power is removed. Enclosure construction satisfies UL/CSA approvals for North American installations.
A plain shaft transmits torque through clamping hubs or shrink discs and includes a frontal centering hole for precise face-mount tooling. To protect internal bearings from vapor or dust in classified zones, a shaft seal is installed at the output end. The free end carries a DIN 332 'DS' thread so extraction screws can be applied during service without damaging the running surface. These shaft-end features support accurate alignment during assembly and controlled removal when the motor is uncoupled from driven equipment. The housing and winding arrangement suit motion axes installed where flammable gases may be present.
