Motor speed power curve
Nettet16. aug. 2024 · Motor speed is a very important characteristic. You need it to match the range where you use it for best efficiency. It wouldn't make sense to use a motor capable of 160 rpm at 80 rpm. Have a look at some efficiency curves for motors, and you'll see what I mean. The high efficiency is biased towards the top of the rpm range. see here. Nettet16. feb. 2011 · Nominal voltage: The recommended maximum voltage across the motor terminals, and the voltage for which the speed-torque curve (below) is plotted. The motor can be powered with less or more …
