Electric motor

Abstract

A multi-phase electric motor comprises a stator comprising a plurality of wire coils surrounding a non-magnetizable core; a rotor with permanent magnets embedded therein, the rotor being disposed adjacent to the stator, the rotor being mounted on a rotatable drive shaft; a power source; a position sensor operably connected to the rotor; and a control circuit operably connected to the power source, the position sensor, and the wire coils, for controlling distribution of electrical energy to the wire coils. In this motor the control mechanism transfers electrical charge from a first coil to a second coil.

1 . A coil and magnet arrangement for a multi-phase electric regenerating motor, comprising:
 a first pair of magnets separated by a distance B, each magnet having a width W, length L and height L;   a second pair of magnets separated by a distance B, each magnet having a width W, length L, and height L, separated from said first pair of magnets by distance A;   a coil having a core with a height RC,   wherein W≦A, and L≧A.   
     
     
         2 . A coil and magnet arrangement according to  claim 1 , wherein B≦A. 
     
     
         4 . A coil and magnet arrangement according to  claim 1 , wherein C≧W. 
     
     
         5 . A coil and magnet arrangement according to  claim 1 , wherein HM≧HC. 
     
     
         6 . A coil and magnet arrangement according to  claim 1 , wherein B≦A, C≧W, and HM≧HC. 
     
     
         7 . A method for modular control of an electric motor comprising:
 generating a digital PWM signal containing a clock frequency and duty cycle set as one of a performance limiter or based on the natural response sessonant frequency of the motor coils;   generating timing and polarity start and stop pulses,   generating a throttle signal;   generating a protection signal;   logically determining based on the digital PWM signal, the timing an polarity signal, the throttle signal and the protection signal, when to turn the motor on and off to achieve a maximum saturation of magnetic field within a coil, prior to complete collapse of the field for the off portion of a duty cycle.
