Products with High IP Ratings

Postby om_tech_support_JT » Wed Mar 15, 2017 2:56 pm

Q: I need some splashproof electric motors and fans with high IP ratings for a food processing application where the whole machine would be sprayed down with water from time to time. Can you explain the IP rating to me as well as differences in protection between your numerous IP rated products?

A: IP means "ingress protection" against dust and water. The dust resistance and waterproofing degrees of protection for equipment are classified according to EN 60529 (Specification Degrees of Protection Provided by Enclosures (IP Code)) (also IEC 60529) as well as EN 60034-5 (Rotating Electrical Machines - Part 5: Degrees of Protection Provided by The Integral Design of Rotating Electrical Machines (IP Code) - Classification) (also IEC 60034-5). A brief explanation of the number codes as well as the testing methods are indicated below:

With regards to your specific washdown application, we offer many motor and fan products with high IP ratings. I would suggest that you first decide what IP rating you require for your application by determining what IP code you need to protect against your specific dust or water conditions, then look for the type of motor or fan that fits that criteria and your application requirements.

Below are some of our products which offer high IP ratings:

With our FPW series watertight AC induction motors, we offer a rating of IP67. The 1st digit code "6" means a completely dust-proof design which cannot be penetrated by powdery dust. The 2nd digit code "7" means that the product is still usable after immersion in water under specified conditions (immersion to a depth of 1 meter for 30 minutes). We achieved this IP rating by using a special anti-corrosive coating, oil-shield protection around the output shaft bore, o-ring between the motor/gear case junction, and a SUS303 type stainless steel output shaft. Please see image and link below for more information.

We also offer a terminal/power relay box to protect the motor cables from its environment.

With our BMU series brushless DC motors, we can offer a rating as high as IP66. The 1st digit code "6" means a completely dust-proof design which cannot be penetrated by powdery dust. The 2nd digit code "6" means protection against strong water jet from all directions (sprayed water jet of 100 kPa at a rate of 100 liters/minute for 3 minutes from all directions at a distance of 3 meters. The new BMU Series achieves IP66 class protection through the use of a stainless steel shaft, oil ring, oil seal and new, redesigned motor connector type. Please see image and link below for more information.

With our AZ series Alphastep closed-loop stepper motors, we offer an IP66 rating (for 42 mm or larger frame sizes). The 1st digit code "6" means a completely dust-proof design which cannot be penetrated by powdery dust. The 2nd digit code "6" means protection against strong water jet from all directions (sprayed water jet of 100 kPa at a rate of 100 liters/minute for 3 minutes from all directions at a distance of 3 meters). We also use o-rings and rubber gaskets to seal the motor (please see image below). The IP66 rating excludes the mounting surface and connector portions of the motor and its cable.

With our enclosure fans, we can offer a rating as high as IP55 for either suction or exhaust type axial flow fans. The 1st digit code "5" means protection against powdery dust. The 2nd digit code "5" means protection against water jet from all directions (sprayed water jet of 30 kPa at a rate of 12.5 liters per minute for 3 minutes from all directions at a distance of 3 meters). The way we achieve these ratings is by adding an additional cover, filter media, frame and/or finger guard. We offer these add-ons either before market (pre-assembled kit) or after market (sold separately). Please see link below for more information.
