    Understanding Continuous Speed in DC Motor Applications

    Brushed and Brushless DC motors have two traits that make them easy to control for several applications.  The first is the relationship between voltage and speed, and the second is the relationship between current and torque.  Both relationships are separate from each other but below you can see how they are used together to provide […]

    Fractional HP Motors and the Problem with Single Load Points

    When specifying a fractional hp motor for an application sometimes the only data available is a single load point, or the rated load point of the motor being specified.  In order to better explain why one load point usually isn’t enough to fully define a motor we’ll compare two different sample motors to show the […]

    Is Your Motor Overrated?

    When buying a standard, off the shelf motor, it can be difficult to find the correct motor size and performance for a given application.

    Planetary Gear Reducers: Rotating Around the Sun

    Planetary gear reducers belong to the epicyclic family of reducers, since the planet gears trace epicycloidal curves in space—very similar to how the popular kid’s toy, the spirograph, works[i]. Simple planetary gears are arranged with a centrally located, externally toothed sun gear that meshes with one or more externally toothed planet gears. As the name […]

    What’s Your Frequency?

    A question we are often asked is “Can a motor that is rated for 60 Hz be run at 50 Hz (or vice versa)?” There are several issues that can arise when running a motor at a different frequency than the name plate frequency. In our previous blog,  AC Motor Basics,  we explained the synchronous […]
