Product Description:

The MSS142F-0700-FA-N0CN-NNNN is a stator manufactured by Bosch Rexroth Indramat for the MSS Synchronous IndraDyn H Motors series. Intended for spindle-driven machine tools, this open-frame component supplies the stationary magnetic field needed by a synchronous kit motor while allowing the rotor to be placed directly on the driven shaft. The part supports compact, high-speed installations in the 142 mm frame class, where space, weight, and thermal control must be addressed during machine design.

The winding set is optimized for a rated shaft speed of 7000 rpm, making it suitable for applications that require constant torque at elevated rotational speeds. Heat generated during operation is removed through liquid cooling, and the aluminum housing includes a dedicated stator cooling jacket that routes coolant around the active laminations. Electrical insulation follows class F, allowing winding temperatures up to 155 °C without degradation. Because the unit has an IP00 protection rating, it must be installed inside an enclosure that prevents contact with internal parts and protects the stator from contamination. The F-length stator stack establishes the axial length of the active motor section. Winding variant 0700 sets the electromagnetic characteristics and resistance values required by the compatible drive.

A 1.5 m power cable with flying leads exits the stator axially, simplifying cable routing in tight spindle housings. Coolant enters through a threaded port with a G 1/8 fitting, while the return port uses an M16 × 1 thread to accommodate a compact hose adapter. The axial orientation of both coolant ports aligns with the cable outlet, allowing the electrical and cooling connections to be routed along the same channel. Safe operation is permitted at ambient temperatures from 0 to +40 °C; operation outside this range may reduce thermal capacity or insulation life.
