Product Description:

The MSS202B-0150-FV-N0CN-NNNN is a stator supplied by Bosch Rexroth Indramat for the MSS Synchronous IndraDyn H Motors series. As a kit component, it forms the stationary part of a high-torque spindle motor used in precision machine tools and other automated equipment. When combined with its matching rotor and drive electronics, the unit converts variable-frequency currents into controlled mechanical rotation, providing a compact, liquid-cooled spindle platform for continuous industrial duty.

The stator body has a frame size of 202 and a frame length code of B, which correspond to the laminated core diameter and axial stack required for the target torque range. Its 0150 winding is rated for a nominal speed of 1500 rpm, allowing constant-power operation across typical spindle speed ranges. Thermal management is handled by liquid cooling. A surrounding stator cooling jacket directs coolant over the outer frame to remove copper and iron losses without external fans. The windings use Class F insulation, which permits winding temperatures up to 155 °C while maintaining dielectric strength. The coil ends exit the housing through an axial cable outlet. The stator is supplied without a motor encoder, allowing a feedback device suited to the drive system to be installed separately.

Installation conditions reflect the stator’s open construction. A protection rating of IP00 means the stator must be built into a guarded spindle housing to prevent contact with internal components and limit contamination. The permitted ambient operating temperature is 0 to +40 °C, keeping the coolant and winding insulation within their allowable limits. Power is delivered through a 1.5 m power cable with flying leads, simplifying direct termination inside the machine frame. The axial cable direction keeps conductors clear of rotating parts. Its mechanical arrangement supports accurate alignment with the matching rotor while maintaining a consistent air gap during assembly and operation.
