Can electrical motor produce a spark?

  1. Mar 4, 2013 #1
    Hi Guys,
    I am building an equipment to Zone 2 explosive atmosphere.
    Machine will be powered by the pneumatic motor. I just had an argument with my boss. He says that I need to order an atex approved motor and I say that I don't because the motor will never produce any spark.
    What are your thoughts on this?

    I'm not 100% sure but I believe an insulation issue could cause a spark...

    I mean...I'm pretty sure when motors burn out they do cause some sparks...

    An electric motor can absolutely produce a spark, and depending on the motor, some of them produce sparks all the time as part of normal operation.

    Your post title asks if electric motors can produce a spark, while you question says you are using a pneumatic motor. Which is it?

    Given that they do produce zone 2 air motors, there is apparently a true risk. I would suspect that an air motor has a risk of static discharge. Electric motors of all types can produce sparks...even brushless motors will spark during failure.
