This may be a little basic for some. Sorry in advance...
I would like to use a large 3ph motor to perform a fast, controlled, stop.
The rated motor torque is 850Nm @ 242A.
My inverter claims to be able to deliver a short duration current of 460A.
Calculating the torque constant KT = 3.51Nm/A (from the rated figures 850/242 = 3.51)
Could I realistically expect 460A x 3.51Nm/A = 1615Nm of reverse torque for a short duration?
Or in fact, like when a motor is starting would the ratio of current to torque be a non-linear relationship?
(The motor would be running at normal load and speed and then attempt to decelerate as fast as possible.)
