Internal Product Review
The 1MS310B-6E-A1 is a stator for a 1MB frameless spindle motor with liquid cooling. Frame size 310 and motor length code B support a well-matched fit for high-speed spindle assemblies. An integrated connection cable routed through the stator end and the 6E winding variant make this unit a strong choice for precision machine builds.

Product Description:
The 1MS310B-6E-A1 from Bosch Rexroth Indramat is supplied as a stator subassembly for high-speed spindle drives. It belongs to the 1MB High-Speed Asynchronous Motors series and serves as the stationary magnetic core around which a matching frameless rotor is installed. In machining centers and test rigs, the stator generates the rotating magnetic field that drives the spindle, allowing compact direct integration into the machine structure instead of relying on a conventional housed motor.
The stator is equipped with a 1.5 m loom that functions as the power and sensor connection cable, and the harness is routed through the stator end so wiring can be completed without extra junction points. Heat is removed by liquid cooling, which draws losses away from the core laminations and helps maintain a stable operating temperature at elevated spindle speeds. To support this cooling method, the assembly uses an aluminum cooling jacket that spreads localized heat before the coolant carries it away. The unit uses frame size 310, allowing it to fit spindle housings built for this diameter class in modular spindle systems.
The stator uses winding variant 6E, a coil arrangement selected for the voltage, current, and base frequency used by compatible high-speed spindle inverters. Its axial stack height corresponds to length code B, providing a medium magnetic length that balances torque density with a compact envelope. Because it is supplied as a frameless spindle motor component, the stator is pressed into the machine builder's housing and paired with a matched rotor sleeve during assembly. This layout allows the surrounding spindle structure to provide mechanical support while the stator supplies the electromagnetic field needed for high-speed rotation.
