1. Product Characteristics

Small Precision Motors
For Vacuum Cleaners, Lap Top Computers,
and Electric Car Motors 

It is imperative to use high-efficiency motors in lap top computers and electric car parts to minimize the loss of electricity.  In order to meet such needs, low core loss electrical sheets were developed for small precision motors.  The core loss was greatly improved by removing phosphorous and sulfur to the very lowest level during the steel manufacturing process.
