Motor and Gearbox Pairing

July 21, 2016

Originally, gears and the structure that houses them (called gearheads, gear reducers or gearboxes) were created for two main reasons: To increase motor torque To enable more adjustments to be made to a motor’s speed. However, advancements in technology has enabled gearboxes to make additional progress in permissible inertia and vibration reduction. These changes are […]

Oil or Grease: Orientation, Cleanliness, & Efficiency (Part 4/4)

July 7, 2016

  Factor #5 & #6: Orientation, Cleanliness Although fairly self-explanatory, orientation of the application—the location, position, and accessibility of the motor—effects the practicality of using grease or oil. Some motors must operate in tight spaces or are required to function at angles at which thinner lubricants, like oil, will have a greater chance of leaking […]

Oil or Grease: Load (Part 3/4)

June 30, 2016

  Factor #4: Load As you might guess, an increased load increases the stress upon your motor, just as a full trailer increases the stress on your truck or a child on your shoulders puts increased pressure on your back. In motors, this stress produces heat, which creates a heightened potential for lubricant evaporation. Spill […]

Oil or Grease: Operation & Vibration (Part 2/4)

June 23, 2016

  Factors #2 & #3: Hours of Operation and Vibration Weather extremes are hard to miss. Even if you don’t have a thermometer somewhere nearby or an app on your phone (or a degree in meteorology), it doesn’t take much to realize what sweltering hot or blistering cold feels like. As a result, it’s not too […]

Oil or Grease: Climate (Part 1/4)

June 16, 2016

  Factor #1: Climate   Unless a person lives on a space shuttle or in a vacuum-sealed, climate-controlled, sterilized building where no one leaves and nothing enters, people can expect to find the evidence of climate on the surrounding area and its objects—machinery, motors, patio awnings, washing machines or otherwise. Both internal and external wear […]

Oil or Grease: 7 Factors to Remember

June 9, 2016

Maybe your gearbox leaks, and you are debating on whether or not to swap oil out for grease. Maybe your grease oxidizes at an impractical rate causing rust, and you’re thinking oil might be a better option. Or maybe you’re just tired of the sulfur-like smell that lingers on your hands after you’ve had to […]

Fractional Horsepower Motors Explained

May 26, 2016

At first glance, fractional horsepower appears fairly simple. Its name also serves as its definition: it’s a fraction of one horsepower, or rather, 746 Watts (1 hp) or below. However, in the fractional horsepower electric motor industry, “less than one horsepower” covers a wider range than most manufacturers are capable of building. Because of this, […]
