Product Description:

The Bosch Rexroth Indramat MSS482A-0200-FA-N0CN-NNNN is a water-cooled stator module from the MSS Synchronous IndraDyn H Motors series. In multi-axis machining centers or gantry systems, this component forms the stationary half of a direct-drive synchronous motor, providing the electromagnetic field that propels a matching rotor without gear reduction. The arrangement supports the precise speed and position regulation required for high-accuracy industrial automation tasks. Because the coils are embedded directly in the machine frame, the design shortens the drivetrain and reduces the number of mechanical parts requiring maintenance.

Magnetic forces generated by the winding stack impose an axial pull of 1100 N on the machine bearing seats and a radial pull of 659 N toward the stator yoke. Guides, spacers, and bearing supports must be sized to withstand these loads during operation. The winding set has 3 symmetrical phases, enabling standard IndraDrive inverters to supply sinusoidal current. Power conductors enter through an opening sized for a 30 mm cable diameter and should use copper leads with a cross-sectional area of 16.0 mm² to keep electrical losses within thermal limits. With a protection category of IP00, the module must be installed inside a suitable enclosure so that live parts remain shielded from accidental contact.

Liquid cooling removes heat produced by copper losses in the winding. A coolant flow of 4.0 L/min must pass through the internal channels, and system pumps may supply up to 6 bar without exceeding the housing pressure rating. Under nominal conditions, the stator introduces a hydraulic resistance of 1.2 bar, which must be included when calculating total pressure loss in the cooling circuit. Mechanical attachment uses 18 M8 fixing threads with a depth of 16 mm arranged around the circumference. A single M8 grounding stud and dedicated sensor terminals support connection of the integrated SNM.150.DK temperature sensor and an external KTY84-130 sensor using 0.5 mm² and 0.25 mm² leads, respectively.
