High Performance traction motor.
Permanent magnet motor 200kW
Rotor core with skewed magnets to offer perfect sine wave Back EMF
Rotor slice with custom magnet shape and grade N45UH
Magnets skewing is implemented for a perfect sine-wave Back EMF, and the best efficiency possible.
The magnet optimum skewing angle formula is :
Optimum Magnet skewing angle
 Δ α = optimum magnet skewing angle
P= nr of magnets
Z= nr. of slots.
Example for my motor 60 slot 10 pole:  Δ α = (360/20)-(360/60)= 18-6 = 6 degre skewing is ideal for zero cogging torque.
New arrived tool with isolated inputs to allow to measure switching losses for each transistor. This is very important, I`m using it to fine tune the controller switching timing, and measure the switching losses.
Contrroller Vesc Based software
Live test with the Vesc at 11kW
Torque Vs Speed combined with efficiency map
We use 0.2mm thick lamination to achieve highest efficiency on the market, above 97%.
Motor housing ready first 4 motors
Inner cooling ring being machined
Rotor for the 130kW version
Rotor flanges
Achieved efficiency even at low loads and low voltage is higher then 96%
