IP Ratings for Electric Motors: Quick, Clear, and Crucial

Ever wondered what those IP ratings on electric motors actually mean? Let’s break it down fast and fun—so you can pick the right motor without breaking a sweat.

What Are IP Ratings?

An IP rating tells you how well an electric motor is protected against:

  1. Solids like dust.
  2. Liquids like water.

It’s a two-digit code:

  • First digit: Protection from solids (0–6).
  • Second digit: Protection from liquids (0–8).

The higher the number, the better the protection.

Popular IP Ratings You Should Know

  • IP55: Keeps out most dust and stands up to low-pressure water jets. Perfect for indoor and light outdoor use.
  • IP66: Totally dust-tight and can handle powerful water jets. Great for heavy-duty or outdoor environments.
  • IP67: Dust-tight and can survive being temporarily dunked in water. Ideal for wet or humid conditions.

Why Does It Matter?

Choosing the wrong IP rating can wreck your motor. Too much dust or water, and it’s game over. A higher rating means better protection, but you don’t always need the toughest motor—just one that’s right for the job.
