Safety Standards for Fractional HP Motors: UL, CSA, & CE

June 17, 2014

Groschopp’s standard product line of motors are designed to conform to a number of different safety standards, including UL, CUL and CE.

UL Certification

The UL and CUL marking on Groschopp motors means that the motor has been independently tested by UL and that it conforms to the relevant UL safety standards. For the United States, UL 1004-1 is the general standard for rotating electrical machines and UL 1004-3 is the standard for thermally protected motors. For Canada, CSA standard C22.2, No. 100 is the standard for Motors and Generators and C22.2, No. 77 is the standard for Motors with Inherent Overheating Protection. All standard Groschopp motor models conform to these standards, have been independently tested by UL and are regularly inspected by UL to assure continued compliance. The picture below shows the relevant UL markings that are found on Groschopp motors. From left to right, these markings mean that a motor has been evaluated to United States Standards, to Canadian Standards, and to both United States and Canadian Standards. This particular marking means that Groschopp motors are considered “UL Recognized Components,” which means they are meant to be used as components of a larger product.

CE Compliance

Groschopp motors can also be CE compliant. A CE marking on a motor means that the motor is in compliance with European Union legislation and the relevant directives and standards. The two applicable directives for Groschopp motors are the Low Voltage Directive 2006/95/EC and the Machinery Directive 2006/42/EC. The Low Voltage Directive is meant for electrical equipment and its safety objectives concern any hazards that may arise due to electricity, like shocks or fire. The Machinery Directive is meant for all machines and its safety objectives concern any hazards that may arise due to moving parts, noise, vibration, fire, explosions, radiation or emissions. Many CE directives are self-certifying, meaning the manufacturer of the equipment is responsible for ensuring that their equipment meets all the relevant requirements for the CE mark (shown below).

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.
