What to Know When Customizing a Universal Motor

October 27, 2016

The golf course, the cheese factory, the printmaking shop and the carnival—these are all places (plus many more) where universal motors will be found. Similarly, just as the location of these applications are diverse, so are the actual motors themselves. This need for versatility and variance calls for universal motors to typically be custom-made to […]

Synchronous & Induction Motors: Discovering the Difference

October 13, 2016

A simplistic division of fractional horsepower motors would be AC, DC, Brushless, and Universal. However, just as shoes can be broken down into work boots, dress shoes, sneakers, and so on, each motor category has various subgroups. AC motors, for example, can be split into synchronous and induction (also known as asynchronous) motors. While both […]

Holding Brakes: What They Are and What to Look For

September 29, 2016

Brakes are not a foreign concept. Simply put, they are the mechanisms within our cars that enable us to slow down for yellow lights and stop at red ones. However, as a few of us have probably found, our cars need more than just brakes for the common, everyday functions of an intersection stoplight. We need […]

Why You Probably Don’t Need a Pancake Motor

September 1, 2016

A pancake motor not only sounds like an appealing choice, but it looks like the ideal motor. In fact, in a runway show of motors, axial flux motors (also referred to as pancake or disc motors) would probably steal the show. And with good reason. Although they vary in functions, they tend to sport many […]

Duty Cycle: What You Need to Know

August 4, 2016

Continuous Duty During the hunt for an electric motor for a particular application, duty cycle is routinely brought up as an important factor in determining your final motor selection. Often asked is the question of, “Will this application require a continuous duty cycle or an intermittent one?” In other words, will the application be a […]

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 […]
