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.
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
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%
