MSS162J-0200-FA-N0CN-NNNN

The Bosch Rexroth Indramat MSS162J-0200-FA-N0CN-NNNN from the MSS Synchronous IndraDyn H Motors series is a precision-engineered spindle motor stator designed for demanding industrial automation environments. It features an axial Cooling Connection and a Volume of Coolant Duct of 0.109 liter to maximize thermal management under heavy loads. The unit operates at 50Hz and a nominal Voltage of 230V, delivering a Power rating of 500W with an overall Efficiency of 85%. With a Mass of 46.1 kg and a Permissible Inlet Pressure of 5 bar, this stator ensures robust mechanical stability and reliable thermal performance.

Reliability is further enhanced by its single-phase design and omission of an integrated encoder, simplifying installation and maintenance. The stator winding exhibits a resistance of 0.46 Ω at 20 °C, while longitudinal and crosswise inductivities measure 2.52 mH and 7.48 mH respectively for precise current control. The rotoric assembly, mated to this stator, maintains a thermal time constant of 5.1 minutes, ensuring sustained operation without thermal runaway. The combined stator–rotor package achieves a torque constant of 2.4 Nm/A and a voltage constant of 171 V/min⁻¹ at 20 °C, supporting peak torques of up to 275 Nm at currents of 130 A.

Engineered for continuous-duty applications, the MSS162J stator integrates seamlessly into liquid-cooled drives, minimizing temperature spikes and extending service life. Its sturdy frame and coolant duct architecture make it ideal for high-precision machining, spindle drives, and other torque-intensive tasks. The result is a dependable, high-performance solution for advanced motion control in industrial settings.
