Motor controller

Started by en2 July 25, 2014
Hi !

I was planning on creating one motor controller for my crystalyte motor.
Its three phase 1,5kw blcd motor.

Can someone share ideas on pwm design and or basic schematics ?

Just buy one on ebay. http://www.ebay.com/itm/HIGH-QUALITY-3HP-2-2KW-10A-220-250V-VARIABLE-FREQUENCY-DRIVE-INVERTER-VFD-NEW-a7-/300652886556?pt=LH_DefaultDomain_0&hash=item46004efa1c#ht_15352wt_1184 220 volt 1 or 3 phase in. 220 volt 3 phase out http://www.ebay.com/itm/LJL-1-5KW-7A-2HP-SAFETY-STOP-COMPLIANT-VARIABLE-FREQUENCY-DRIVE-VB-110V-GDJ-57-/111417407483?pt=LH_DefaultDomain_0&hash=item19f0feb7fb#ht_9191wt_892 120 volts in, 1 or 3 phase in, 220 3 phase out. lots of choices starting at $0.99

If you're a raw beginner, I suggest that you look for development kits from the microprocessor makers. Get a kit that does what you want, sorta, then modify it from there. -- Tim Wescott Control system and signal processing consulting www.wescottdesign.com

Try this book:- "Electric Drives and their Controllers" by Richard M. Crowder, ISBN 0-19-856565-8. -- ******************************************************************** Paul E.

Thanx for suggestions guys, but i would like to build one from teh 
scratch. I made few dc controllers up to 500W but i newer try to make 
one with three phase..

Well, the book suggestion should be spot-on, then. Motor controllers is a book-length subject, if you gather all the bits and bobs into one spot. As for starting with a demonstration board (or schematic) -- having a working example of something you've never, ever built before is often a great help in making sure that you're not doing something profoundly stupid. -- Tim Wescott Control system and signal processing consulting www.wescottdesign.com
I have a design that (in theory) can handle up to 5KW with suitable
cooling, although I only run it at a few hundred watts.

Basically, though, the "design" is just a motor control MCU and a motor
driver chip, plus a few discretes around it.  Most of the problem is
solved in software or on-chip peripherals.

----------- Could not agree more :-). I will definitively do that. @DJ quite nice design and idea. Did you try to upgrade this to higher power output ? btw. which linux distro ?. Am on ubuntu 12.04.
