Can you show me how to build a high torque permanent magnet motor?

I viewed a you tube video showing a permanent magnet motor built and demonstrated by Rolls Royce  I would be overjoyed to know how how to build one to power a generator.

BLDC is a good choice if you can overcome its electronics driver.Brushless DC motors use permanent magnets and have a reasonable torque-speed specification.there are a lot DIY for BLDC on YouTube and Instructables,but I have never seen any detail+calculation for wire-Gauge and permanen magnet tesla in all these DIY.If you can find a detailed description please share it here.

Hint: Check your local wreckers or scrap yard for old washing machines.
Some front loaders use a motor design similar to the link above.
This way you safe a lot of wiring and getting parts to work together as you already have the mounts, bearings and all ;)

Mrerza, thank you for your reply, i have a friend that does rewinding and together we will see if we can make it work although we will need more information.

All motors including, PM motors and all rotary machines, Torque is just a Force and increases in proportionally to rotor radius.. Power is Energy and is proportional to Torque X Speed.. Speed is measured in RPM (Revolutions Per Minute)..

Please indicate how many Watts and rpm Generator Power you want to make a PM motor for...

Yes, speed is important because AC frequency is measured in Hertz which is related to RPM and if the generator is two pole or four pole machine.. A four pole generator only needs to spin half as fast as a two pole generator for producing the same Frequency..
