How To: Distinguish the Difference in IP Ratings

February 1, 2012

IP66 Ingress Protection Ratings Groschopp Inc.Many times a customer will call Groschopp looking for a standard or custom motor that needs to be protected from the surrounding environment involving water, dust, or foreign debris.

When this situation presents itself, Groschopp’s  Application Engineers start to ask questions about Ingress Protection (IP) rating. As defined in International Standard IEC 60529, the IP rating classifies and rates the degrees of protection against entrance of foreign objects and liquids. The IEC standard aims to help users better understand the ratings.

IP ratings can be broken down into two sections – solids and liquids. Groschopp motors come standard off the shelf with an IP rating of IP44. This means that the motor is protected against objects down to 1 mm in size and splashing water will not harm the motor.

In some cases, Groschopp’s customers ask for special sealing techniques to be applied to the motors. These requests are a result of the application specification for a harsh environment or the presence of liquids in the application. Groschopp’s AC, PMDC and Brushless DC motors can be configured up to IP66 when needed. The rating ensures that the motor is protected against dust particles and from the effects of water being sprayed at high pressure from any angle without harming the motor.
