    Welcome to the PF. What is the context of your question? What are you going to use this motor for?

    The attached URL has torque vs RPM curves for four different types of dc brush motors, the most common of which are the shunt wound, the series wound, and the permanent magnet. The shunt wound dc brush motor has the flattest torque curve. See

    I took a quick glance at the link. Why is the shunt wound DC motor speed-torque curve different than a permanent magnet motor. I find this suprizing. Both would seem to have a constant applied flux. Do you happen to know?

    I saw that, and was also puzzled.
