Re: About Encoders...
Early days, BLDC had discrete hall type devices mounted somewhere on the end of the stator or housing with a magnet or similar on the rotor.
For some time now, motors have used the hall equivalent tracks on the actual encoder, it proves a bit more accurate also.
Did you compare USdigital for price? I have not used them personally but they seem to have some competitive prices.
