Product Description:
The Bosch Rexroth Indramat MKE037B-144-AG0-BENN belongs to the MKE Synchronous Motors series and is classified as a servo motor for potentially explosive areas. Its role in automation is to deliver closed-loop torque and speed control where combustible gases or dust are present. The motor uses winding code 144 to match the electrical characteristics of associated drive controllers, enabling consistent torque generation at rated current. By combining a flameproof housing with precision feedback, the unit supports positioning tasks on mixers, conveyors, and filling stations installed inside Category 2 zones.
Compliance with ATEX standards and an enclosure rated at IP 65 allow the motor to resist dust, water jets, and ignition sources during operation. Its specified ambient range of 0 to +40 °C is the permissible room temperature without output derating. All power, signal, and protective earth conductors land in a top-mounted terminal box, and the cable routing leaves the housing on side B so cabinet layouts can keep cable glands at the rear. Ingress along the shaft is limited by an integrated seal, and the stator windings use Insulation class 155 (F), which tolerates winding temperatures up to 155 °C. The absence of a holding brake shortens the overall length and suits systems that use mechanical clamping at standstill. With no forced cooling, convection through the ribbed casing maintains thermal balance within the stated limits.
Position feedback is generated by an optical encoder that provides 128 increments per revolution and communicates through the single-turn Hiperface protocol. A smooth plain shaft transmits torque without keyways, while a frontal centering hole helps align couplings during assembly. Threaded engagement at the end of the shaft follows DIN 332 “DS” thread dimensions, which simplifies attachment of puller tools during service.
