help with current limiting resistors | |
Could anyone help me work out what resistors I will need for the following motors using a PC 12v @ 8A PSU,
all of the motor are unipolar (6 wire)
Motor 1, 4volt 4.1ohm per phase ( there is no current rating on the label)
Motor 2, 4volt 7.6ohm per phase (" ")
Motor 3, 3volt 9.2ohm per phase (" ")
also if I upgrade to a 24v PSU would I double or half the resistance?
I have got my unit working but the motors get very hot quickly, so I cannot run it for long for testing don't want to burn the motors out, my driver boards can run at 35v @ 6A .
Your help with this matter would be fantastic.
Regards
