Auto industry looking to Copper Alliance as alternative to rare earth materials

The auto industry may be looking for alternatives especially when it comes to the cost of rare earth materials, but it is the Copper Alliance and their video that will be used to enlighten the SAE 2012 Powertrain Electric Motors Symposium for Electric and Hybrid Vehicles in Detroit.

Permanent magnet motors require rare earth metals, while copper rotor induction motors do not. This is significant as prices for rare earth metals have increased more than 400 percent in the last two years as of April 2012, according to metal-pages.com.

This is precisely why the International Copper Association in alliance with the Copper Development Association will show a video demonstrating the strength of the copper rotor motor for EVs April 23 at the SAE 2012 Powertrain Electric Motors Symposium for Electric and Hybrid Vehicles in Detroit. Auto industry experts interviewed for the video weigh in on the viability of the copper rotor induction motor as an alternative to the permanent magnet motor for electric vehicles.

For example, the copper rotor induction motor is a strong alternative to the permanent magnet motor for electric vehicle traction when comparing cost, performance and reliability, say automotive industry leaders in a new video released today by the Copper Alliance.

The video features industry experts from Remy International, Inc., Fukuta Electric & Machinery Co., and AC Propulsion, all companies that have supplied the copper rotor induction motor for electric vehicle use.

This is actually the first time auto industry experts have gone on record saying the copper rotor induction motor is a strong alternative to the permanent magnet motor when considering price, reliability and performance. It's a cutting edge technology that is quite possibly the wave of the future for electric vehicles -- especially as prices continue to rise for rare earth metals from China.
