Product Description:
The 1MS200H-4D-A2/S010 stator is manufactured by Bosch Rexroth Indramat and belongs to the 1MB High-Speed Asynchronous Motors series. It forms the stationary electromagnetic core of a frameless spindle motor, producing the rotating field required for high-speed machining and other automated tooling when paired with an external rotor and a compatible inverter. By keeping the magnetic circuit fixed while the shaft components spin, the unit enables compact spindle assemblies that can sustain continuous duty at elevated speeds. This layout supports integrated spindle assemblies where compact dimensions, stable magnetic performance, and sustained operation are required for precision machining and similar automated processes.
Thermal regulation is handled by liquid cooling, which circulates coolant through the housing to remove losses more effectively than air. The stator uses Frame Size 200, giving a standardized outside diameter for integration into 200-class motor mounts. It has a 4D winding variant, which sets the turns-per-phase ratio so voltage and current align with high-speed drive ratings. Power and sensor leads exit through a 1.5 m loom guided out of one stator end, which can simplify routing in enclosed spindle housings. For internal temperature monitoring, the assembly carries NTC resistors and PTC resistors, allowing the connected drive to react before overheating affects insulation or magnetic stability.
Additional over-temperature protection comes from bimetals that open a contact once the laminated stack reaches a preset threshold. The axial dimension corresponds to motor length code H, providing a longer iron stack for higher continuous power density without increasing diameter. The stator has compatibility with third-party drives, so its impedance, feedback, and protection devices follow open industry practices. An aluminum cooling jacket surrounds the laminations, and its high conductivity spreads heat evenly into the liquid path to help maintain dimensional stability during load transients.
