Product Description:

The MSS162J-0200-FA-N0CN-NNNN is a synchronous servo unit produced by Bosch Rexroth Indramat within the MSS Synchronous IndraDyn H Motors series. Designed for liquid-cooled drive axes in presses, extruders, and heavy material-handling stations, the motor converts electrical power into rotational motion. Its high output supports precise automation tasks that place substantial demands on the drive axis.

Under continuous duty, the machine delivers 25.1 kW of mechanical output while maintaining a shaft speed of 2,000 rpm. At that operating point, the electromagnetic system sustains a torque of 120 Nm and requires a phase current of 50 A. This current-to-torque relationship is governed by a torque constant of 2.4 Nm/A, allowing drive controllers to predict load response with simple proportional algorithms. A voltage constant of 171 V per 1,000 rpm indicates the back electromotive force that the inverter must overcome, while the 0.46 Ω winding resistance establishes the baseline for copper losses. The 5.1-minute thermal time constant shows that the stator temperature responds quickly to load changes. Accurate thermal models are therefore needed to manage temporary overloads without excessive winding temperatures.

For short bursts, the rotor can reach 275 Nm without demagnetization. Dynamic behavior is influenced by the stator’s transverse inductance of 7.48 mH and longitudinal inductance of 2.52 mH; these values limit how quickly current can rise during abrupt acceleration. Heat produced by these transients is removed through an external coolant circuit that must supply at least 4 L/min and may be pressurized up to 5 bar. The open-frame IP00 protection class restricts installation to closed machine enclosures that prevent contact with energized or moving components. The 46.1 kg stator mass requires rigid mounting brackets capable of supporting the assembly and maintaining alignment under operating loads.
