DC Motor and Speed Control Unit – Sherline Products

About Sherline Motor and Speed Control Units. The 90-volt DC motor provides far more than that of the 1/2 HP AC/DC motor we used to offer prior to 1994. A DC motor offers its maximum torque at low RPM where you need it most, so the full speed horsepower rating of an AC/DC motor can be a little deceiving as far as offering practical, usable power.
