A universal motor is a series-wound motor — meaning that the field and armature windings are connected in series — and is mechanically commutated with brushes and a commutator. Although its construction is very similar to a series-wound DC motor, a universal motor incorporates several modifications that allow it operate properly on either DC or AC […]

The KinetiMax has an integrated speed control loop with speed […]
What is linear behavior for DC motors?
When the term “linear behavior” is used to describe a system, it implies that the system’s output is directly proportional to the input. Unlike their wound-field counterparts, permanent magnet DC (PMDC) motors exhibit linear behavior. The use of permanent magnets means PMDC motors don’t need separate field excitation, and therefore, don’t experience the electrical losses […]
