Radial Brushless DC Pipe Motor

Radial iron core bypass true brushless dc motor, where the iron bolt directs the magnetic field past the vertical copper current conductor sleeve/pipe going up-down, the end of the main axle is non-ferrite material like aluminium, so the magnetic field prefers to go though the bolt around the radial magnet iron pipe. An implementation of homopolar DC motor type, uses high current low voltage, F=ILB, U=vLB.
