1MS310F-6A-A1

The Bosch Rexroth Indramat 1MS310F-6A-A1 belongs to the 1MB High-Speed Asynchronous Motors series. It features a Motor Size 310 frame with a Motor Length F and dual Windings Code 6A, 6B configurations. This stator is engineered specifically for frameless spindle applications and direct-drive spindle motors. Designed to support high-precision machining, it seamlessly integrates into milling, grinding, and turning centers.

The 1MS310F-6A-A1 delivers a Rated Speed 900 RPM under steady load and peaks at a Maximum Speed 3600 RPM for rapid acceleration requirements. It generates a continuous Rated Torque 480 Nm and sustains a Rated Power 35 kW output. The assembly weighs 133 kg and is optimized to operate within an Operating Temperature 0 to 40 °C window. A robust Protection Category IP00 housing protects the stator core, while the Liquid Cooling circuit channels fluid through an Aluminum Cooling Jacket to absorb stator and rotor losses. Power and signal are routed via the integrated 1.5 m Cable, providing reliable electrical connection and installation flexibility.

Engineered for machine tool integration, the stator’s frameless design offers compactness and precise rotor alignment when fitted into spindle housings. The rugged cooling jacket and tight manufacturing tolerances ensure long-term reliability and thermal stability under continuous operation. Ideal for high-speed machining centers and transfer lines, the 1MS310F-6A-A1 delivers consistent performance in demanding industrial environments.
