What do you like about this subject? OLDER Three or single phase OEM motor information is getting more and more difficult to find. It is satisfying to help when a problem has been previously worked with little in results.

What do you still hope to achieve/learn in this field? For over thirty years I have been involved with the repair and diagnosis of motor/apparatus mechanical issues. There are always new issues.

Something interesting about this subject that others may not know: A brush can increase the operating life of a motor by a factor of 2 or more. Simply sweeping the contaminates or materials from a process, off the motor case, will allow the motor to cool itself as designed. A "hot" motor is not necessarily a "bad" motor.

Something controversial or provocative about this subject Differences in the motor code number or speeds require additional consideration in starting methods and choices of control. The number of starts a motor can withstand in a defined amount of time is frequently overlooked. Motors do fail on their own. However a significant amount of motor failures are the result of something preventable. As well, the cause of failure in rarely diagnosed.
