correction:

- what you appear to have is an inside out repulsion motor. Once much more
common than at present, they do have good starting torque but the
maintenance is higher than that of other single phase AC motors because of
the need for a commutator - i.e. synchronous switch. Your switching is
simply a way to replace the commutator. Note that there are now "brushless
repulsion motors.

It is a motor which receives little or no attention in most modern machines
texts although it was once mentioned in many texts. I had to go back to
White & Woodson, "Electromechanical Energy Conversion" (Wiley, 1959)
(essentially graduate level material and ideas in this were used by
Westinghouse to make a universal motor which could be run as any kind of AC
or DC machine using the appropriate connections- the fact that it was just
as lousy as an induction motor as it was as a DC motor didn't appear to
matter) which has the basic equations for such a motor.
