Product Description:

The MSS182A-0250-FR-N0CN-NNNN is a stator supplied by Bosch Rexroth Indramat for the MSS Synchronous IndraDyn H Motors series. As a stator for synchronous kit spindle motors, it forms the stationary magnetic field component that couples with a rotor to drive high-speed machine-tool spindles and other precision axes in industrial automation. The stator is intended for installation within a compatible spindle assembly rather than operation as a separate motor. Its cable exits axially, simplifying routing from the spindle housing toward the drive connection.

This stator attains a rated synchronous speed of 2500 rpm when matched with its designated winding variant. Heat generated at that operating point is removed by a closed-loop cooling circuit that uses liquid cooling flowing through a stator-cooling jacket. The coolant ports are arranged radially around the frame to reduce the clearance required for connected hoses. Electrical integrity is supported by Class F insulation, which permits winding temperatures up to 155 °C before derating becomes necessary. Because the unit has IP00 protection, it must be integrated into a sealed spindle housing or cabinet that prevents contact with contaminants and exposed electrical components.

A factory-installed power lead measuring 1.5 m terminates in flying leads, allowing suitable connectors to be crimped or soldered for the enclosure layout. Coolant enters and leaves through threaded adapters sized at G 1/8, and these fittings are positioned on the radial face. Operation is limited to ambient temperatures from 0 to +40 °C, which is suitable for standard machine-tool enclosures with controlled internal conditions. The stator has a frame size of 182 and a frame length code of A. Its standard design, radial coolant-port placement, and lack of a motor encoder leave room for an external feedback device within the spindle assembly.
