•No lost of Material: save of costs

•No lost of Material: Eco-Friendly

•Light Appliances: Easy to handle for the user

•No integration of the engine in the appliances: more freedom in the Design

Engine Circuit Command Control for the Engine

•Relation between Speed and Electromotrice force:

E= U-R*I E = k * Phi * w

•Relation between Torque and Flux:

C = k * I * Phi
