US Emerson Motors 

US Motors, a division of Emerson Electric, was purchased in 2010 by Nidec Motor Corporation, but there are still many motors in use with the US Emerson name on the nameplate. US Motors provides a wide range of industrial and commercial electrical motors for HVAC, pump, swimming pool, agriculture, and severe duty applications, plus more.   

All US Motors Nidec on Square One’s website are sold brand new with a manufacturer's warranty. 

Nidec Motors Warranty  

Nidec Motor Corporation allows products to hold a limited warranty for 12 months from the date of installation. This date cannot exceed 18 months from the date of manufacture, with an exception for specific products which can be found on the US Motors website.  

A deferred/extended warranty is available by adding a 5% addition to the net price of the motor, and then the warranty period will be for one year from the date of initial operation, but without passing 60 months from the date of shipment. Before this deferred warranty is put into place, the customer must hire a Nidec motor Corporation Engineer or authorized NMC Service Station to make sure the motor is in “as shipped” condition.
