Q. What voltage are these motors designed to work at?
A. Hi David, thanks for your question. Using 37-0510 as an example – the minimum voltages would be V=IR = 2.1(phase current) x 1.2(phase resistance) = 2.5V 37-0511 = 6.2V 37-0512 = 3V However the manufacturers advise using a 24V bi-polar driver set to the appropriate current for enhanced performance. We hope this helps.
