Product Description:
The 1MS160N-4C-A1 is a stator for frameless spindle assemblies in the 1MB High-Speed Asynchronous Motors series. It generates the stationary magnetic field that drives the rotor in high-speed machining centers and automated tooling stations, giving the spindle a compact electromagnetic core for precise torque production at elevated speeds. This design suits machine spindles that operate at very high rotational speeds, where stable magnetic behavior and efficient heat removal are important for continuous cutting duty. Its frameless form also allows the stator to be integrated directly into a spindle housing without adding the bulk of a separate motor enclosure.
The unit includes a 1.5 m loom connection cable routed through the stator end, which simplifies internal wiring and avoids extra terminals inside the spindle assembly. Cooling is provided by liquid cooling, with coolant moving through internal channels to remove heat from the stator core during sustained operation. Frame size 160 sets the outer diameter and matches housings built to IEC 160 dimensions. Length code N indicates the axial stack height, which sets the active copper volume and continuous power capacity. An aluminum cooling jacket surrounds the laminations, and the material helps move heat away quickly while keeping overall spindle mass lower. Smaller temperature differences across the assembly also help maintain stable running conditions during long machining cycles.
The winding set follows variant 4C and matches the voltage and current profile used by Rexroth high-frequency inverters, which helps limit copper loss during high-speed operation. As part of the 1MB High-Speed Asynchronous Motors series, the stator fits complementary rotor assemblies intended for the same motor platform. The assembly is vacuum-impregnated, which helps secure the windings, improve insulation stability, and support reliable operation under the vibration levels common in spindle service. It is ready to install in the spindle housing and can provide consistent magnetic performance from initial operation onward.
