Product Description:

The MKE047B-144-GG1-BENN is a servo motor engineered by Bosch Rexroth Indramat as part of the MKE Synchronous Motors series. Designed for automated systems installed in hazardous zones, the unit converts electrical energy into regulated mechanical rotation so actuators and conveyors can operate safely in chemical processing and paint finishing equipment. Its synchronous design supports precise speed and position control during repeated starts, stops, and speed changes, and the enclosed motor construction is suited to applications where ignition protection and stable motion performance must be maintained at the same time.

Electrical and mechanical interfaces are arranged on the B-side of the frame, and power and feedback conductors terminate through a terminal box, allowing rigid conduit routing inside protective enclosures. Motion is held during power loss by a built-in brake that provides 2.2 Nm of holding torque. The housing is ATEX compliant, so surface temperatures remain below the ignition limits required for the assigned zone. Thermal endurance is supported by an insulation system rated 155 (F), which allows continuous winding temperatures up to 155 °C without premature insulation breakdown during continuous duty and frequent thermal cycling.

The motor uses 4 pole pairs with the internal 144 winding code to produce smooth low-speed torque under sinusoidal drive control. Its stainless-steel output uses a plain shaft finished with a DIN 332 "DS" thread and a front centering hole, so couplings can be pulled into position accurately during assembly. A shaft seal blocks vapor or dust from entering at the bearing seat, which helps protect the lubricant and internal bearing area during operation. The threaded center and centering hole also support controlled removal of mounted components without prying against the bearing system.
