Product Description

Rexroth Bosch Indramat’s MSS162F-0310-FA-N0CN-NNNN is a high-speed synchronous stator under the well-regarded IndraDyn H motor series. Specifically, it works seamlessly with MRS rotors under the same product series. During operation, this stator safely operates at an ambient temperature range of 0 to 40 degrees Celsius at a non-condensing relative humidity. When allowed to operate normally, this stator can provide a changing magnetic field that is moving at a velocity of 3,100 rpm. Impressively, at this synchronous speed, the corresponding rated torque delivered by the rotor can reach as high as 90 Nm. With its winding type and construction class, this three-phase stator can reach a power and current of 29.2 kW and 64 A, respectively.

The MSS162F-0310-FA-N0CN-NNNN can also function well outside its rated or nameplate values. Particularly, at a DC bus voltage of 750 V, this stator can induce a synchronous speed of 15,500 rpm. In total, this stator only employs four pole pairs, or eight poles, spaced 45 degrees apart. When operated at lower speeds, the MSS162F-0310-FA-N0CN-NNNN can induce a peak torque of 200 Nm. At this maximum torque, the possible peak current of 170 amperes may safely be accommodated for a short period of time. Assuming a 1N rotor type, the unit has an inertia value of 0.022 kg(m^2). For a 2N rotor type, the equivalent inertia value is 0.024 kg(m^2).

Based on Rexroth’s documentation, the MSS162F-0310-FA-N0CN-NNNN has the following constants at 20 degrees Celsius: 1.41 Nm/A, 110 V per 1000 rpm, and 0.23 ohms. The first constant indicates the sensitivity of the torque output with respect to the input current applied. The second constant relates the voltage change relative to the shaft speed. Finally, the third constant refers to the average value of the stator’s winding resistance.
