Explosion Proof, Washdown, & Food Grade Servo Motors

Explosion-proof versions of motors are designed to minimize the risk of explosion, and to contain any internal explosion that may occur without allowing it to propagate to the outside environment.

Kollmorgen Explosion Proof Motors

Every day Kollmorgen pushes the boundaries of motion to deliver optimized solutions that satisfy even the most demanding application requirements in the harshest of environments. This includes helping machine builders effectively meet the often complex and time-consuming requirements for ATEX certification.

The ATEX certification controls which machinery and equipment are allowed in explosive environments. Industries may include but are not limited to mining, oil and natural gas refining and flour mills. Ask customers a few open questions to see if they're meeting the criteria:

  1. Does the application environment in which your machine will operate have its own effective source of ignition?
  2. Will the motion components in your machine be used in a potentially explosive atmosphere?
  3. Will your machine operate under normal atmospheric conditions?

If the application meets these criteria, with Kollmorgen they have a market leading option to meet the ATEX certification while also being able to leverage the co-engineering and high performance that Kollmorgen is able to provide.
