Product Description:
The 1MS160F-4A-A2 stator is supplied by Bosch Rexroth Indramat for high-speed spindle applications. As a stationary field assembly for a frameless motor, it provides the electromagnetic structure that works with a matching rotor to generate torque inside integrated machine-tool spindles. This arrangement helps machine builders place the active motor components directly in the spindle housing, which supports compact layouts and stable high-speed operation in machining, grinding, and routing equipment. Because the stator is installed as part of the spindle body rather than as a separate motor housing, it also helps preserve available space for bearings, sensors, and the rotating shaft assembly.
With a frame outside diameter of 160 mm, the stator fits housings prepared for this motor size. Heat from the windings is removed by liquid cooling, and the integrated aluminum cooling jacket provides an efficient thermal path to the coolant chamber. The electrical characteristics follow winding variant 4A, which matches the designated spindle inverter and supports the intended resistance and inductance values for the application. A pre-assembled 1.5 m connection loom is routed through the stator end, which reduces internal wiring congestion and helps keep clear axial space around the rotating assembly. This cable arrangement also simplifies internal routing where the spindle cartridge has limited room for separate lead management.
The magnetic stack uses motor length code F, which gives the stator a deeper lamination package for higher continuous output without increasing the outside diameter. This version is suited to applications that require high surface speeds together with moderate torque in a limited installation envelope. Supplied as a stator for 1MB frameless spindle motor, the component can be combined with a matching rotor, bearing system, and feedback hardware inside a purpose-built spindle unit. That approach allows the surrounding machine structure to be tailored to the required speed range, balance quality, and positioning accuracy of the finished spindle assembly.
