Axial Flux motors

  1. May 3, 2012 #1
    There is wonderful clames about Axial Flux electric motors.
    For example this company http://www.yasamotors.com/technology/products/yasa-400 [Broken]
    claims it developed such 20 kg motor which is able to deliever peak power of 165 kW!
    Is it some type of scam? What disadvantages could have such type of motors?
    I thought that to create stronger magnetic filed you need to have larger current.To have larger current you need to use more copper.Typical electric motors have 1 kW power for 1 kg of copper.How could they beat it?
