Electric Motors and Motor Control Circuits Repair & Maintenance


Seminar Overview



Electric motors tend to fail regularly and replacing them is commonplace. But did you know that it doesn't have to be that way? While motor failure may appear to be a common problem, it is more likely that the real enemy is a wrong application or control circuit issue. Failure of the motor can be just a symptom of perhaps an even more serious problem that lies ahead.  This electrical course on Electric Motors and Motor Control Circuits helps maintenance workers identify what the real issue is when a motor burns out and how to prevent it from happening again.



This 2 day seminar is just $990.
