AC Motors: Built-in Cooling Fans

Postby om_tech_support_JT » Wed Oct 13, 2010 4:58 pm

Q: Do you provide built-in fans in your AC motors?

A: Yes. We do provide built-in fans in our bigger AC motors such as 60w and above. The built-in fans provide additional cooling to the natural convection method. Additionally, on 6w or smaller AC motors, we provide impedance protection which limits the motor operating temperature at a certain level by restricting the increase in current in a locked condition. On 15w or bigger AC motors, we provide thermal protection which will automatically turn the motor off if it senses an overheat condition.
