Energy costs and downtime can be greatly reduced by instituting a motor management plan. Part II of this three-part series specifically addresses the establishment of a motor failure policy and the development
of purchasing specifications. Part I addressed the general aspects
of a motor management plan, including the first steps of creating a motor inventory and guidelines for motor repair and replacement. Part III will examine motor repair specifications
as well as preventive and predictive maintenance.
Reducing losses and increasing profits by instituting a motor management plan is what this series of articles is all about. Here in Part I, we discuss how to create a motor inventory and establish repair-or-replace motor guidelines. Subsequent topics in this
three-part series will address (Part II)
motor failure policies and purchasing
specifications, and (Part III) repair
specifications and preventive and predictive maintenance, respectively.
The secondhand on the Doomsday
dial ominously spins around the face,
slowly but ever so surely inching the
motor industry towards its inevitable
terminus:
This issue we take a long, hard look at motor efficiency, and you should, too. After all, electric motors used in industrial settings are the single largest consumer of electricity in the United States. Upgrading your electric motors is not only good for the environment, but it’s
also good for your bottom line. Sure, saving electricity lessens
the burden on our country’s energy infrastructure. But it
also saves you money in the long run.
When talking about high-end machining or manufacturing applications that include direct-drive technology, one of the key advantages of utilizing this particular transmission method is its endurance. Because of the very nature of direct-drive motors they are able to operate at peak performance levels indefinitely — without any kind of wear or aging — as long as the motor isn’t pushed past its capacity.
Unfortunately, because this isn’t a perfect world, unexpected things can happen which can cause the motor to overheat. Whether the heat source is due to a parameter being input incorrectly, or an unexpected external force causing more resistance than expected — it is important to have certain forms of thermal protection in place. Since torque motors are built in such a way that they cannot be
repaired and yet maintain their efficiency, it is vital to prevent any overheating — thus precluding the
need to purchase a new one.
