Product Description:
The MSS202A-0200-FA-N0CN-NNNN is supplied by Bosch Rexroth Indramat as part of the MSS Synchronous IndraDyn H Motors series. Delivered as an open kit motor, its stator is intended for direct integration into rotary machine frames, allowing compact drive layouts and improved positional stiffness without a separate housing. In industrial automation, it acts as the electromagnetic core of a high-precision direct-drive axis, generating torque once the matching rotor is seated within the air gap. This arrangement supports applications that need accurate rotary motion while keeping the mechanical structure closely integrated with the machine.
The stator permits an allowable axial assembly load of 420 N and a radial installation load of 1658 N, which helps protect the laminations from distortion during press-fit mounting. Liquid cooling keeps the winding temperature stable, and the cooling circuit requires a continuous pressure drop of 1.6 bar with a flow rate of 3.0 l/min. The coolant circuit can withstand peaks up to 6 bar without leakage. Protection for installed electronics is limited to IP00 because the kit motor is supplied without its own enclosure, so safeguarding must be provided by the host machine. Threaded ports G 1/4 and M22 × 1.5 accommodate supply and return connections, and the temperature sensor leads use 0.25 mm² KTY conductors with 0.5 mm² PTC wires to report thermal status to the drive. Ten evenly spaced stator holes support balanced clamping forces when the assembly is drawn into the motor housing.
Power phases terminate on a connection strand with a diameter of 22 mm, and the drive cables are sized for AWG 8 conductors to match the winding current density. The stator is drawn into its carrier with M6 / 12 mm Deep fixing threads, giving sufficient engagement length to resist torsional recoil under acceleration. Once clamped, the laminations align flush with the machine bearing seats, which helps maintain a uniform air gap for the rotor and steady magnetic flux. The open construction simplifies routing of sensor wiring and allows external shields or enclosures to be positioned to suit the target axis.
