Advantages of DC motors in industrial appliions

Advantages of DC motors in industrial appliions

+

 · DC motors are easier to install than AC motors, require less maintenance and are easier to repair than their AC counterparts. Many industrial systems may already be set up to use DC motors. If that's the case, replacing a failed motor with another DC model is quick, easy and painless. Replacing it with an AC model will require you to redesign ...
