  • Plant Engineering When it comes to motors how hot is hot

    2013-9-10 · If motor is so constructed that its surface is about 20 C cooler than the winding the surface temperature would be 10020 = 80 C (176 F)—i.e. much too hot to touch safely Remember that this is a conservative design so the surface temperatures of many motors will be much warmer.

  • When should you choose linear motors vs ball screws

    2014-12-2 · Another benefit in positioning accuracy is provided by the encoder. While ball screws typically use a rotary encoder mounted to the motor for positioning feedback linear motors use a magnetic or optical linear scale for position feedback. The linear scale measures position at the load which gives a more accurate reading of the actual position.
