Product Description:
The 1MS310B-6B-A1/S010 stator is produced by Bosch Rexroth Indramat for the 1MB High-Speed Asynchronous Motors series. Designed as the stationary element of a frameless spindle motor, it creates the rotating magnetic field that accelerates a hollow-shaft rotor to high surface speeds. When integrated into milling, drilling, or grinding spindles, it allows CNC and other automation platforms to apply direct-drive torque without a through-bolted motor housing, which saves axial space inside machine headstocks. Because the stator mounts directly into the spindle structure, it supports compact machine layouts where installation space is limited.
The stator has a frame size of 310, giving a wide bore for bearing systems used in high-speed spindles. Cooling is done by liquid cooling, so coolant circulated through the outer jacket removes heat without relying on cabinet airflow. A factory-fitted 1.5 m loom exits one end of the stator and provides pre-terminated power leads for connection. Protection against thermal overload is provided by embedded NTC, PTC, and bimetal sensors that send temperature data to the connected drive for derating or shutdown. The stator uses a 6B winding that matches the voltage and frequency ranges required for high-speed inverter operation. This combination helps the motor assembly maintain stable thermal conditions during long machining cycles and repeated speed changes.
The motor length code is B, which gives the stator a medium axial package for tooling heads with limited installation space. The housing uses an aluminum cooling jacket to improve heat transfer to the liquid circuit during continuous duty. The stator is suitable for third-party drives, so it can be paired with non-Rexroth inverters in multi-vendor control systems. That compatibility is useful where a machine platform already uses an established external drive architecture. Its insulation system and mechanical design support sustained operation at the elevated speeds expected in contemporary machining centers.
