Maximum speed:
The former maximum speed Nmax = 3900 rpm obtained with Un =400 Vrms and Nn
=3900 rpm leads to the new maximum speed Nmax2 given as follows:
N
3476
N max 2  3900 *
 3476rpm
N max 2  N max * n 2
Nn
3900
N.B.
If the rated voltage increases (Un2 > Un), the new rated speed Nn2 and the new
maximum speed Nmax2 will be greater than the former ones Nn and Nmax. Moreover
you will have to check that the drive still shows able to deal with the new maximum
electric frequency.

Warning: If the main supply decreases, you must reduce the maximum
speed accordingly in order not damage the motor.
In case of doubt, consult us.
Rated power:
The former rated power Pn=2520 W obtained with Un =400 Vrms leads to the new
rated power Pn2 given as follows:
U
360
Pn 2  2520 *
 2268W
Pn 2  Pn * n 2
Un
400
Rated torque:
The former rated torque Mn = 6.17 Nm obtained with Un =400 Vrms leads to the new
rated torque Mn2 given as follows:
2268
Pn 2
M n2 
 6.23Nm
M n2 
