Product Description:

The MSS102F-0300-FA-N0CN-NNNN is a stator assembly from the MSS Synchronous IndraDyn H Motors series produced by Bosch Rexroth Indramat. As an open kit motor element, it is intended for direct integration into machines where the rotor is supplied separately and high torque density is required in limited space. In industrial automation, this stator couples with drive controllers to provide precise, electrically commutated torque for indexing tables, printing cylinders, and similar servo-controlled axes. This format lets the machine structure support the motor directly, which can be useful where a conventional housed motor would take up too much radial space.

Because the stator carries no housing, its ingress rating is IP00, signaling that the surrounding machine frame must supply environmental shielding. The motor design is listed as Open (Kit Motor), meaning the laminations, windings, and cooling passages are fully exposed for close-coupled installation around a customer-supplied shaft. Power leads exit as a connection cable sized at AWG 14, so the drive can deliver phase currents without excessive voltage drop over short distances. For liquid cooling, the inlet manifold uses a port tapped G 1/8, and the expected pressure drop through the internal channel is 0.7 bar, a figure that helps the builder size the pump and verify adequate flow at the stator. The open layout also allows the cooling circuit to remove heat close to the windings during continuous servo operation.

Thermal stability is maintained when the coolant supply never exceeds 6 bar and remains at a volumetric rate of 2.5 l/min; staying within these limits helps prevent erosion of the copper tubes and preserve winding insulation. The return side of the circuit terminates in a thread size of M16 × 1, allowing standard metric fittings to be installed without adapters. Eight stator mounting holes, each prepared with a thread of M5 / 12 mm Deep, secure the assembly to the machine frame. A single ground lug provides the path for safety grounding and helps protect the windings from potential voltage differentials during operation.
