Variable sized magnets in motors

Source: http://www.hybridcars.com/gm-patents-electric-motor-multiple-magnet-lengths/

Effectively, the tabs will allow the stacks to accept either short or long magnets–the tab will support the shorter magnet halfway down the aperture or get pushed out of the way upon inserting a longer magnet. GM claims there will be at least a 25-percent difference in magnet lengths.

What this means is a common motor core whose expensive, permanent magnets can be sized for the vehicle. This increases the commonality of parts to reduce manufacturing costs yet right-size the motor(s) to the vehicle.
