WHITEPAPER – Harsh Environment IP66 Motors & Gearmotors

August 24, 2011

Total Protection Against Dust and Strong Jets of Water

Description

The harsh environment IP66 motor and gearmotor product line from Groschopp is designed to provide reliable, trouble-free operation and long life in applications where dust and/or moisture intrusion are present. Designed and built with special physical and electrical protection features, the Harsh Environment products are protected against dust that may cause premature commutator, brush and bearing failures and water that may cause corrosion or electrical failures.

IP66 rated products are inherently safer since water intrusion greatly increases the risk of electrical shock. Oil intrusion in a motor is also a risk, particularly with brush-type motors. The brushes may “stick” and the motor can fail if exposed to oil.

Temperature fluctuation is frequently common in these same harsh environments. Condensation, as a result of temperature change can also create water ingress, resulting in reduced life and premature failure of the motor/gearmotor.

Groschopp has developed and supplied motors and gearmotors for automotive applications and other rugged applications where the environmental conditions are extremely harsh for decades. These products continue to reliably perform event when splashed with salt spray, water, harmful chemicals, dirt, mud and extreme temperature variations. This extensive experience and knowledge in developing motors for many different harsh environment applications has resulted in the most  durable family of IP66-rated fractional horsepower motors and gearmotors in the industry.

Temperature

Groschopp IP66 Permanent Magnet DC series motors have been subjected to rigorous hot/cold tests where the motor is heated to 250° F and then immediately submerged in an iced water bath at 33° F. Even with these temperature extremes and submersion the motor was so well sealed that post-test evaluations revealed no water ingress or performance compromise.

Customized Tests

IP66 PMDC motor designs have been tested for 96 hours of continuous operation in a salt fog, per customer testing requirements. Groschopp can tailor testing protocols and provide performance results to meet specific OEM design requirements. These same environmental and performance tests can be applied to any Groschopp motor or gearmotor design.

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.
