New motor design will help the EV world!

I have tested many motor designs and found that?its not all about rpm,s but torque that is the most important in any motor today.

?Having design my Gator Controllers and looking for more amps for more torque is not the answer.

What? is needs is to redesign the ac/dc motor, with a bigger armature having permanent magnets?in it.

This will have a diameter of say: 20inch with outer dc pulse field like advance step motor design.

This will do away with the speed controller and have a PWM without and IGBT or Mosfet.

The power output in torgue is unmatch by any dc/ac motor as smaller dc motor lose there torque at higher rpms?and have higher amps at start up, this new design would use less? amps and better torque output and it will reduce the rpms also.

Having reduce the weight about 50% compare to today motor would be the way to go.

I'm? not saying the best way, but its all about torque and not just rpms.
