Characteristic values for dynamics
| V/f | VFCPLUS | ELSM® |
|---|---|---|---|
Torque control time | – | ≥ 2 msValid in voltage control range, in field weakening range < 5 ms. | ≥ 150 µs |
Time constant speed controller | – | ≥ 4 – 6 ms | ≥ 6 ms |
Rotational speed ripple | The speed ripple is mainly determined by the total mass moment of inertia, the torque ripple, and in particular the mechanical structure. It is therefore not possible to specify a general value. | ||
