Product Description:
The MKE045B-144-GG1-KN belongs to the MKE Synchronous Motors series from Bosch Rexroth Indramat. It is a servo unit engineered for motion tasks in hazardous production cells where dust or gas may be present, integrating directly with explosion-protected drive systems to deliver precise position and speed control to conveyors, pick-and-place axes, or dosing modules. Classification as a servo motor for potentially explosive areas confirms that the enclosure, insulation system, and surface temperatures meet ignition-risk limits required by ATEX and similar safety directives. This arrangement allows controlled torque production in areas where excessive surface temperature and unintended ignition sources must be minimized during normal operation.
Electrical terminations are routed upward because the connections are on the top of the housing, simplifying cabinet layouts that stack multiple axes vertically. Power and feedback conductors enter through a cast-on terminal box, which shields the wiring interface against contaminants and mechanical impact. Stopping and power-off holding demands are handled internally; the motor is supplied with a holding brake that clamps the shaft when current is removed. Torque transmission to couplings is direct, since the rotor extension is a plain shaft without keyways that could trap debris. To prevent lubricant escape or the ingress of fine particles, a dedicated shaft seal is fitted at the housing mouth, supporting IP protection and long bearing life.
For centering the output element, the shaft face contains a precision frontal centering hole that aids alignment during assembly and service. Threaded retention uses a DIN 332-compliant DS thread, allowing puller tools or transport eyes to be attached without damaging the running surface. This thread format also supports controlled handling when the motor must be moved or removed from a tightly fitted machine interface. Electromagnetic behavior is set by winding 144, and this coil set determines the voltage constant and thermal load that the paired inverter must accommodate.
