How to Reverse AC Motors

March 23, 2018

Motor rotation is essentially created by the manipulation of wires and magnetic fields. Thus, you can often reverse AC motors by switching the wire connections. This is as easy as unhooking and re-crimping the designated wires. (Note, not all AC motors have the ability to be reversed, but all of Groschopp’s AC motors can be). […]

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 […]

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, […]

Standard Insulation Class Ratings for Groschopp’s Motors and Gearmotors

May 5, 2016

Electric motors are categorized by temperature into groups called insulation classes which rate what temperature a motor can safely run at. Temperature ratings are important to understand because a motor running too hot can cause premature motor failure. UL 1446 Temperature Classes Maximum Temperature at Hottest Spot A* 105°C E (European) 120°C B* 130°C F […]

What’s Your Frequency?

October 1, 2013

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 […]

How to use the Motor Search Tool

Narrow your search by selecting motor type, gearbox, voltage, and phase options for your desired motor.

Select a dominant variable: choose one of the three parameters to narrow your search. The selected variable determines which slider bar you will be able to manually move.

Use the slider corresponding to your dominant variable to further narrow your motor selection. The other sliders will automatically move to show available ranges based on the range of your selected variable.

Results will upload as your search criteria changes. If you have any questions regarding your results or how to use the search tool, you can chat with us using the green tab on the left-hand side of your screen.

Note: Groschopp Universal motors are custom built to fit your application so no additional options are available to narrow the search. Selecting the Universal motor type will prompt a message taking you to the Universal product page.
