1MS376A-QB-A2

The 1MS376A-QB-A2, Bosch Rexroth Indramat, 1MB High-Speed Asynchronous Motors series stator delivers high-speed performance in a frameless synchronous motor design optimized for demanding spindle applications. The unit features a robust Motor Size: 376 body and a standardized Motor Length: A to ensure compatibility with industry-standard rotors and machine tooling. A precision-engineered laminated core minimizes eddy-current losses, while an integrated Stator Design: With Aluminum Cooling Jacket channels liquid coolant around the winding pack for efficient heat removal. With an Insulation Class: F winding system and an unprotected housing of Protection Category: IP00, this stator meets the core requirements for high-dynamic machinery under controlled environmental conditions.

Designed for continuous operation, this stator is rated for ambient temperatures from 0 to 40 °C and can be stored safely between –20 to +80 °C. The attached terminal box supplies power via a Cable Length: 1.5 m connection with reduced diameter wiring insulated at the stator end. Temperature monitoring sensors embedded in the winding provide real-time overtemperature protection, and the cooling circuit uses corrosion-inhibited coolant to maintain thermal stability. The stator is qualified for installation at elevations up to 1000 m above sea level without derating performance.

Engineers will appreciate the modular, frameless construction, which allows seamless integration into custom spindle assemblies and transfer lines. The aluminum cooling jacket combined with advanced temperature sensing ensures high reliability under rapid duty cycles, minimizing downtime. Ideal for turning machines, grinding centers, and high-speed machine tools, the 1MS376A-QB-A2 stator offers consistent torque delivery and precise thermal management for maximum spindle uptime.
