Low Volatge Drive Selection Guidance
Low Volatge Drive Selection Guidance
(OP)
Hi Engineers,
I am looking for guidance on selection of Low Voltage Drives on the basis of:
1.Dimensioning- torque,overloadability
2.Performance- V/f control, sensorless vector control,closed loopp vector control,static & dynamic accuracy of speed & torque, respose time
Searching threads didn't help, so I am writing this quetion.
If you can point me to such an existing thread, it would be great!
Thanks in advance,
D'man

There are hundreds of other lesser issues but, for me, that's the "core" process for selecting drives.

Extra low voltage (ELV) usually is below 50 or sometimes 42 V AC.

RE: Low Volatge Drive Selection Guidance
To save time though, here are the 2 FAQs we collaboratively wrote as a jumping-off point to determine the type of drive you may need.
FAQ237-1062: What is Vector Control in a VFD?
FAQ237-1063: How does Vector Control compare to Servo Control?
Specific technical performance values are going to vary from mfr. to mfr., even from year to year within the same mfr., so any published list would be quickly obsolete. My general advice is, determine your performance requirements, maybe even the technology you think you need, then decide who in your local area does the best job of servicing drive customers. Not necessarily repair services, but application support and training, inventory etc. That will ultimately serve you better than any brand name.
