11kw 6-pole motor can be used to adjust the inverter to 1800RPM?
Frequency converter in the 5-50Hz is constant torque frequency, 50-100Hz is constant power frequency, to see what you want to get the effect
Frequency conversion frequency f to 90Hz can. 1800 = 60x90 / 3,3 that is 3 pole, is 6 pole. Regardless of load.
First, the inverter is no problem, I used so much to meet your needs
????? But to see if your motor can run at high speed, or whether the load is small, the power to have a general amount of redundancy.
6-pole motor synchronous speed of 1000, to meet your use to be transferred between 2000 or 1900, that is to say the frequency converter output frequency to be transferred to 90 to 100HZ.
????? Constant torque load is no problem, but the fan torque load to be a small job.
