Copper v REEs in EVs.

The program will address market growth projections, requirements, and cost structures for three varieties of electric traction motors: permanent magnet motors, induction motors, and switch reluctance motors. This year’s symposium will feature expanded coverage of rare earth metals, and, for the first time, presentations on testing and simulation.

Next Monday in Detroit, the American SAE 2012 Powertrain Electric Motors Symposium for Electic  and Hybrid Vehicles is due to take place. The big debate is between old fashioned copper induction motors and the newer smaller permanent magnet motors, relying to greater or lesser extent on rare earth elements.  The red metal alliance is trying hard to shape that agenda in Detroit. Below, King Copper tries to land the first blow via price. 

Of course it’s not quite that simple. “This year’s symposium will feature expanded coverage of rare earth metals, and, for the first time, presentations on testing and simulation.” The metal price is only one feature of what decides which type of motor an EV manufacturer is likely to go with. Perfomance, weight, size, reliability, future development, are all as important to serious EV manufacturers looking to be a long term player in the electric mobility transition. It will be interesting to see what next Monday brings.

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.
