Product Description:

The Bosch Rexroth Indramat MSS202B-0150-FA-N0CN-NNNN is a stator from the MSS Synchronous IndraDyn H Motors series. As an open kit motor component, it is intended for direct integration into high-speed spindles or rotary axes where space and weight savings are critical. When paired with a matching rotor and drive, the stator produces precise synchronous torque for positioning and contouring tasks in industrial automation equipment such as machining centers and packaging machinery.

Liquid cooling is mandatory for this stator, and its construction follows an open kit motor design, meaning the surrounding machine housing supplies the primary enclosure. To maintain thermal limits, a coolant flow of 3.0 L/min must be supplied. At this flow rate, the internal passages generate a pressure drop of 1.6 bar, so the external chiller must overcome that restriction while remaining below the maximum supply pressure of 6 bar. The cooling circuit maintains stable operating temperatures during continuous duty while protecting the seals and winding insulation from excessive pressure. Because the unit lacks its own enclosure, the host machine must provide electrical protection and adequate sealing against contaminants.

The laminated core is subjected to an axial attractive force of 420 N and a radial attractive force of 2,206 N. These forces are transmitted into the machine frame through ten fixing threads on each face, with one dedicated ground connection on each face. Electrical continuity is provided by an M6 ground connection thread with a depth of 12 mm, while matching M6 stator fixing threads with a depth of 12 mm provide uniform clamping. Process coolant enters through a G 1/4 port and exits through an M22 × 1.5 return port, allowing direct hose connections. With a protection rating of IP00, the stator must be installed inside a clean, shielded compartment that prevents contact with energized windings. The surrounding machine structure must also support the magnetic loads and keep debris, moisture, and conductive particles away from exposed electrical components.
