Each magnet has a brmax of 14,800 gauss and pull force of 41.28 kg.To minimize magnetic interference, the carts and rails were made of aluminum alloy and the screws and nuts were made of brass.The resultant attractive and repulsive forces were measured using an imada model ds2-110 digital force gauge.
Looking at the design and how fast magnetic repulsion strength dissipates compared to distance, i question if the top magnet can generate enough repulsive force to completely turn the wheel.A 12 diameter x 18 thick neodymium magnet loses almost a 13 of its power in an 18 of distance.It loses 75 of the force at a 14.
Capacitor motors are of two general types namely, capacitor start and capacitor start-and-run.They are a form of split-phase motor having a capacitor condenser connected in series with the starting or auxiliary winding, which changes current-voltage relationship phase by capacitance and reactance rather than by resistance and reactance as is done in the ordinary split-phase motor.
Using electrical tape, secure it in place and make sure the metal of the wire is touching the wire of the terminal.With the other wire, wrap and secure it around the positive terminal of the battery.It doesnt matter which wire is connected to which terminal as long as both are securely attached to separate.
