    What Impacts Speed Variation On Motors and Why Isn’t It Exact?

    To answer these questions we’ll look at the main motor types: AC Induction, Permanent Magnet (PM) DC (Brushed and Brushless) and Universal motors to discuss why when an ideal speed verse torque curve is plotted does the plot change from one motor to the next. (Note: All these motor types naturally experience drop in speed […]
