2015 Small Motor Legislation

[dickandlois]

This change in legislation will not affect Coach Owners, (unless there are some applications I’m unaware of) but if you need to replace one somewhere. Read the fallowing.

Enacted by the U.S. Department of Energy, the 2015 Small Motor Legislation requires motor manufacturers to stop producing motors that do not meet the new efficiency standards by March 2015. This legislation affects small general-purpose motors between 1/4HP–3HP, with an open construction and NEMA design.

There are a number of benefits, but there is a tradeoff – See last paragraph.

Benefits of new Motors

• The more efficient, cooler-running motor along with the Class H wire, Class F insulation material and Class F lead wires helps provide a longer-lasting motor.

• Increased winding size provides a cooler running motor, improves efficiency, extends bearing life and reduces motor insulation degradation.

• High-grade electrical steel reduces energy losses and improves efficiency.

• Run capacitor provides winding with increased energy to help improve efficiency.

• Tighter machining tolerance between the stator rotor reduces magnetic flux losses.

• Lower-resistance rotors with a special slot design and higher-grade aluminum bars help improve performance and efficiency.

• Some motors may be longer and include an additional capacitor (cap start/cap run) to increase efficiency.

So it you have a tight area for the mounted motor it might prove helpful to get one of the older motors!!!!

Rich,

Thanks for the information. I do not believe that the electric motors used for hydraulic leveling are NEMA design so this legislation should not affect use. Agree or disagree?

Agree, Just wanted to post the change, some of the members have hobbies or personal shop equipment that might be affected.

There is also a chance that there are modified coaches and buses that have used them for some application.
