Toroid Power Electric Motor

Toroid Power Electric Motor:

I started this new topic rather than adding this to the
Toroid Electric Motor post because there are several differences
between the two designs.
This design around the motor shaft rather than operating with a disk.
This motor has the electrical energy going to the rotor where the
other post has the power going to the stator assembly.

This motor package will be more like the conventional motor
package where the disk motor has a larger diameter to the motor.

Why should this motor design be evaluated as an OU device?
1.)  Large reduction or elimination of the braking effect of
the motor assembly.  This is because when the power is turned
on to one of the four coils, it pulls the coil into alignment with
the core in the core assembly moving the rotor in this process.
When the power of the coil with the aligned core with loss the
attraction between the rotor core and stator core material
that allows the rotor to glide instead of breaking in the motor.
2.)  Less electrical power to operate this motor assembly.  This
motor only powers one of the four coils at a time.  The means
each coil operates at a 50% duty cycle.  Since the four coils in
the rotor assembly and the four cores in the stator assembly
are offset from each other.  Each power time of a coil will move
rotor 45 degrees.  So the rotor will have moved 180 degrees after
the four coils have been powered one time.  Then you can power
the coils one at a time so the each of them will of had a second
power time tht moves the rotor another 180 degrees in order
to bring the motor to the starting point.  This process can be
repeated over and over again to produce an efficient motor assembly.

A toroid coil produces more more magnetic force than solenoid coils.
So in theory the torque should be greater as a result of it. 

Mu-metal used as core material produces more magnetic force
with less electrical input power.

So with all of these design improvements that the toroid configuration
offers to a motor design should be highly efficient if not an OU device.

Some other advantages:
Lower heat build up in the motor sue to the 25% power duty cycle in
the toroid coils.
This design does not use permanent magnets which means lower cost
of the motor assembly.

Hello,

Sometimes less is better!

I modified the Toroid Power Electric Motor to be about
half the size as it was without compromising it's performance.

Hello,

Just another option of a Toroid Electric Motor.
It may or may not be better than the other designs.

The larger the diameter of the rotor of this configuration
the greater the torque will be.

The coils in this motor will operate at a 25% duty cycle.

Square Toroid Motor:

The Toroid coil and transformer both contain most if not all of the magnetic flux.
A conventional coil with an air coil does not produce as much of a magnetic force as a coil with a core material in it for the same electrical power to drive the coil.   The material the core is made of makes a big difference on how much magnetic force is created.

If you have the same core material and length and size of wire in two different coils, the first being a straight coil and the second being a toroid coil, the toroid coil will produce a stronger magnetic field. 
So, it only makes sense that you want to incorporate a toroid type of magnetic device into a motor application.  Now since a transformer is similar as the toroid, then the squarish shapes are easier to work with than the round shapes, so that is why I designed the Square Toroid Motor.

In order for me to design a motor with toroid coils, It needs to be done different than a conventional motor.  In conventional motors, you have more than one magnet creating the movement of the motor.  With the toroid coil, it is one magnet moving some core material in order to complete the toroid coil.  It is like having a horseshoe magnet and it pulling core material between the poles of the magnet in order to produce a stronger path for the magnetic flux to flow through.  Since the toroid coil is not a permanent magnet, then I control the attraction when I want to on the core material.  When the power is turned off to the toroid coil, then there is little to no attraction on that core material.

Now the big question is how does the motor power input under load compare to the conventional motor under load.

In working with my latest prototype device, the straight coil used as a load, loads the device a lot more than using the toroid coil on the prototype.  In my mind, this indicates that the toroid motor designs should be more efficient that the conventional motor designs.

Notice that each toroid section is disconnected from the other toroid sections in this latest drawing.  That may be an important design consideration in any toroid motor design.
Notice that none of my toroid motor designs use permanent magnets in them.  Permanent magnets are very expensive, so these motor designs should be more economical to build than my other motor designs. 

This design along with any motor design also require both the most efficient power delivery system to the motor along with a regeneration of the collapsing flux in the core material if you are trying to reach an over unity status of the motor.  You might not get to that point but you will have a highly efficient motor in doing them.  Over unity is the regenerated power being greater than the losses in the system.

The way to get to a motor with a COP > 1 is to have a motor that uses less input power per the torque load applied to the motor than current motor designs.   I believe that the toroid motor design may be a design headed in that direction.
