Notes Day 1 National workshop on electric aircraft and allied technologies - 5

• Quanteon axial flux motor maker startup from IIT Delhi

• Startup is DIPP recognised in 2018

• Gail has invented in startup in September 2019 

• Dassault Opera is electromagnetic simulation software

• Axial flux motor have high torque that is a major advantage 

• CRGO steel is to look weak for transformer but is suitable for axial flux motor 

• Quanteon  has purchased this Steel in tape form from Nippon Steel 

• Fill factor used in the coils is 57 % 

• YASA Motors charge 15 Lac per moter

• Quanteon  technologies charge 15000 

• Stampings used for axial flux Motors cannot be wire cut like Radial flux motor

• In radial flux motor the stampings are arranged in a stack and then cut using wire EDM 

• For axial flux motor each Stamping layer has a different size. These when stacked will form a tapering profile. So independent layers have to be laser cut and stacked to give the tapered profile on which thick copper wire can be wounded and magnet can be inserted on the Rotor

•  Airbus Vahana has a variable speed variable pitch propeller 

• VTOL have two major requirements 

• one is to have a high lift rotor for take-off purposes and other is a low thrust popular for forward flight 

• Blade element theory is widely used for propeller modeling 

• Modified blade element theory also incorporates stalling models in the simula
