I asked a question the other day but am still unsure, I just bought a 0-30v 0-5A dc regulated power supply today and want to use it to play around with various DC motors, I was told I didn't need to worry about a fly back diode with a straight motor one the other question but the store I bought it from still recommended and sold me a 10A07 diode, the data sheet is in this link http://pdf.datasheetcatalog.com/datasheet/mcc/10A07.pdf
My question is, is it really needed?, the guy at the store said its just safer to use one so i figured why not. After looking at the data sheet it seems it can handle up to 1000V reverse voltage so im assuming its good.
The power supply is only a cheap $150 AUD one so im not to sure if it would have the proper protection but I have read that fly back diodes are mainly used with transistors, Is that true and did I get sold something I don't really need or would it still pay to use it anyway? Im completely new to electronics so any help would be appreciated.
Thanks in advance
