Hybrid Horseshoe Toroid Motor

Advantages of this motor design:
1.)     The Toroid coil produces more torque than other coil types.
2.)     The rotor core material closes onto the north and south poles at the same time providing a closed loop for the toroid coil function.  The results more torque than my other toroid motor designs.
3.)     The three toroid circuits greatly reduces any reverse torque conditions that occur in a two toroid power circuits.  This improves the efficiency of the motor design.
4.)     Having several rotor core material sections interacting with the forward stator toroid coil when the power is on increases the motor's torque.
5.)     The toroid coils are divided into three toroid circuits.  This means the number of rotor core sections need to be a multiple of three.  The power rotates between these three circuits in order to have a constant power resulting in constant toque in the motor assembly.  This means the motor will not have any startup problems.
6.)    The more sections that are in the stator and rotor assemblies that create the circular shape in the motor will require a greater switching speed in order to produce the same RPM of the motor.  This is good because the faster the switching of a DC power signal to the motor, the more efficient the power will be.  There is a limit to the upper speed before the output power from the motor will drop off.  But you should not run into that issue for most applications.
7.)     No permanent magnets are needed for this motor.  This will save on the cost of the motor.
8.)     The closer the rotor core material is to the stator toroid coil, the greater the torque will be.  This motor design addresses that issue, by having the rotor core close to the stator toroid when the power is applied. Torque also occurs at both ends of the rotor core assembly with the toroid coil at the same time.

I did not add the switching circuits to this design because there are so many ways to do that function which all would work.

I am looking forward to seeing a response to this design.

Hello,

The drawing from the last post may not have been clear as how the motor operates.
So I added two more drawings.

The motor design uses three circuits so that when the power cycles between
those circuits, is so that the rotor will always have forward torque with the stator
assembly with little to no reverse torque in the motor. 

The reason that the core block comes into into the cut out distance in the coil
is because I want the the torque at the to of the block to be the same as the
torque at the bottoms of the rotor core block.  This will reduce the vibration
that would occur without this feature in the motor design.

The torque quickly weakens the farther the rotor core material is from the
stator magnet in most motor assembly.  That is why I have the the core
material of the rotor at the edge of the stator magnet pole surface.
When the power is turned on, the rotor maximizes its performance in
aligning itself with the stator assembly.

The thickness of the rotor core block can be much thinner in theory that
what I show in the drawings and have the same torque.  The drawings use
a thicker rotor core block only to show the concept of the motor.

questions?

Does this motor design reduce the motor's power draw when the drive
shaft is loaded down?

Hello again,

As I was looking at my most current motor plan,  I was thinking
what could I take from other peoples designs that could make
my design even better that it already is.

I have seen a lot of information of using permanent magnets with
coils on transformer looking devices that claim to provide more torque
in the circuit.  Since we do not have to input more electrical energy
into design in order to get the extra torque,  I thought I would add
that feature into my design.

I have already named many advantages to this motor already,
I will not repeat them.

I would like to know if I am all wet with toroid motor designs, or
do you think they might have a chance of working.

Hello all.

I did some testing of the torque that is produced using different layers
of core tabs from the rotor assembly passing through core tabs of the
stator assembly. 

I tested with tabs that were 1 inch from each other  that did not test
much of an improvement by increasing the number of layers that were in the drum assembly.
Then I tested with tabs made from the material from the thinner core ribbon
I took from one of my toroid coils.  I do not know the thickness or type
or material it was.

The second drawing shows my crude test set up I used to collect the test data.
It would be great if someone else would duplicate this testing.

The first drawing is the most complete of this motor concept so far.
One improvement is no insulation material between the stator and rotor
core assemblies.  I used electrical tape as insulation material in
order to eliminate metal to metal contact between the stator to
rotor core tabs or to either of the magnet poles.
I do not have the machining capabilities to build this prototype motor.

I do believe that as crude as the test fixture I used, that is does prove that
there is an amplification of torque using four layers of rotor tab assemblies
over using one layer.  One layer has 42% of the torque of using four
rotor layers.

What does all of this mean?
1,)  Over twice the torque for the four layer drum assembly.
2.)  The PM/EM stator will add twice the flux and hopefully
twice the torque in the motor assembly. 
Note:  Items 1 and 2 should produce four times the torque to the
motor using the same input power.

3.)  The toroid design has very little flux leakage which means
better efficiency for this motor design than many other designs.
4.)  The toroid circuits operate into three separate circuits.  The
circuits operate alternating between the circuits at a 33.3% power cycle.
This means the motor operates cooler than conventional motors. It
also always has forward torque through attraction and no reverse
torque in this design.
5.)  Have only primary toroid coils with no secondary coils in the design
in order to produce forward torque to align the magnets, makes this
motor a simple design meaning it will not be supper expensive.
6.)  Having multiple stator PM/EM assemblies will require faster
switching speeds which are better for DC switching circuits that
will reduce the power consumption into the motor assembly.
