High Performance Electric Machine Without a Collector

ELECTRIC MACHINE WITHOUT A COLLECTOR WITH HIGH PERFORMANCE COEFFICIENT, wherein it has at its stator a magnetic circuit having at least:

• a pair of stator polar pieces, which form part of corresponding magnetic circuits uniting each end of said polar pieces;
• at each one of said magnetic polar pieces there is at least an induction coil capable of generating a magnetic field, having each one of said polar pieces a salient with a parallepiped profile and a trapezoidal cross section;
• placed in between said polar pieces there is a rotor turning on its axis, having this rotor at least a pair of radial extensions in opposition for each pair of polar pieces in the stator;
• this rotor rotates in close proximity past the ends of said polar extensions;
• attached to the axis of said rotor and turning with it there are means opaque to light, able to interrupt a permanent light beam, having said opaque to light means at least a window allowing the free passage of light;
• facing one side of said opaque to light means and in alignment with said rotating window it is placed a permanent light emitting source while on opposite side of said opaque to light means it is placed a photo resistor, resting said opaque means in between said light source and said photo resistor;
• each time said light beam faces said at least one window, it is allowed a free passage through said window, giving origin to a series of finite light pulses according to the revolutions of the motor shaft, synchronizing said pulses with the rotor's angular position and the number of revolutions of said rotor, thus producing a sequence containing said period of time;
• the passage of light through said at least one window establishes an optical link for each pair of polar pieces, including said optical link said permanent light emitting source and photoreceptor, which is excited by said pulsed light beam every time it receives said time pulse;
• the output of the corresponding photoreceptor is connected to the input of an electronic control circuit, said control circuit presenting a pair of outputs for each pair of stator poles and a recovery capacitor, generating said control circuit a synchronous time sequence with the beginning of the passage of light through the corresponding window, consisting in the discharge of the capacitor charged in the previous time sequence (when said time sequence is not the first sequence of the series of sequences) on the coils of the corresponding pair of polar pieces for a resonant quarter cycle of both coils with the recovery capacitor, and to connect an external power source (voltage) available on a positive terminal and common terminal over said coils to increase the current for a time frame of the pulse and finally reconnecting the coils to said energy recovery capacitor until the energy in said coils is transferred to the energy recovery capacitor, the rotor being turned through the attraction of the magnetic field over said radial extensions, while for the initial time pulse, said pulse is started by connecting said external power source to the above mentioned coils.
