Product Description:
The MSS182B-0280-FA-N0CN-NNNN is a stator produced by Bosch Rexroth Indramat for synchronous kit spindle motors in the MSS Synchronous IndraDyn H Motors series. Because only the stator is supplied, it must be integrated with a separate rotor to form a complete spindle motor. This arrangement allows the motor components to be incorporated directly into a machine spindle rather than installed in a conventional enclosed motor housing. The stator is intended for high-speed spindle drives used in automated machining centers and similar equipment.
At its rated operating point, the stator has a synchronous speed of 2800 rpm, which is paired with the 0280 winding for mid-range spindle speeds. Heat generated in the copper windings is removed through liquid cooling, and the aluminum casing includes a cooling jacket around the active stator length. The open housing has an IP00 protection rating, so the surrounding machine enclosure must prevent contact with internal components and limit contamination. Mechanical integration follows frame size 182, allowing the stator to fit the corresponding spindle housing dimensions. Power is routed through a 1.5 m power cable with flying leads that exits axially, allowing the conductors to run toward the control cabinet without a junction box. The stator does not include a motor encoder, so a separate position or speed feedback device must be selected for the drive system.
Coolant enters and exits through G 1/8 and M16 × 1 threaded connections arranged on the axial end face. This port placement supports direct hose routing where radial clearance around the spindle housing is limited. The stator uses Class F insulation with an ambient temperature range of 0 to 40 °C, and the insulation system supports winding temperatures up to 155 °C. The laminated stack follows frame length B and is fitted closely against the surrounding cooling jacket to transfer heat from the windings to the circulating coolant. The standard design code indicates the regular configuration for this stator, while the axial cable arrangement keeps the wiring aligned with the spindle bore and away from surrounding rotating components.
