So when you are saying it needs about 10W, it means that 24V and 0.5A will be enough ?
If the motor can take up to 1.7Amp and the driver can push up to 45V, isn't it 1.7*45 =~ 60W ?
The link to the motor data does not provide a lot of information. If you measure the resistance of the motor coils you will probably find that the 1.7 amps can be supplied with just 2 or 3v (OHM's law) so the wattage would be that voltage multiplied by the current. For example if it was 2v and 1.7A that would mean 3.4 watts.The voltage of the stepper motor power supply is not relevant for calculating the motor power....R
I understand, So you suggest that in order to calculate the power the motor needs instead of using P = I * V, use P = I ^ 2 * R
I'm still not sure if providing 12V vs 24V vs 36V will do any difference in terms of torque ? (assuming all power suppliers can provide enough current)
I * V and I^2 * R give the same answer. Otherwise OHM's position in the physics firmament will need to be reconsidered Using a higher voltage enables the motor to maintain its torque at higher speeds. It will have no effect at low speeds. When the stepper driver turns on a coil it takes some time for the current to reach its limit. If that time is long compared to the interval between steps then the coil may only be at full current for a short proportion of the step. Using a higher voltage causes the current limit to be reached more quickly.The better motor manufacturers produce graphs showing how torque is affected by speed and voltage. It would be worth browsing to find some just to get a sense of how stepper motors perform. The numbers may not match your motor but the general behaviour will be the same....R
I'm sorry, I'll clarify.I need a full rotation every 2 seconds, meaning 0.5 rpm.With maximum torque I can get.
