Problems solved by technology

Thus, at high rotational speeds (eg, 3000 revolutions per minute), the rate of current reversal becomes very high, resulting in increased cost and complexity for the controller of the motor
Also, a high rate of current direction reversal, although it increases the speed of the motor, results in a higher CEMF and reduces the efficiency of the motor

Embodiment Construction

[0036] As mentioned above, as the number of coils at the stator increases, and as the rotational speed of the rotor increases, the rate at which the direction of current flow to the coils of the motor is reversed must increase. This increase in the rate at which current direction is reversed requires a more complex and expensive motor controller and results in a decrease in the efficiency of the motor. More specifically, increased switching frequency requires more powerful power drivers at the motor controller, which inevitably increases power loss during switching of current direction. It is therefore an object of the present invention to provide a motor capable of operation even with a single coil at the stator, wherein for a given rotational speed (in revolutions per minute) current reversals are significantly reduced s speed.

Abstract

The invention relates to an electric motor, which comprises: (A) a disk-type rotor which comprises: (a) a co-centric shaft and disk; (b) two or more permanent magnets on top or within said disk; and (c) pieces of ferromagnetic material that are disposed between at least two of said permanent magnets; and, (B) a stator which comprises: (d) a diametric coil unit which is disposed along a diameter ofthe rotor's disk, the coil unit comprises: (d1) a diametric rectangular bobbin having a rectangular cavity, said rectangular cavity having a length slightly larger than the diameter of the rotor; (d2) a coil which is wounded around said diametric bobbin; and (d3) upper and lower holes within said bobbin to contain said shaft, thereby to allow rotation of said rotor within the said rectangular cavity.

Description

technical field [0001] The invention relates to the field of electric motors. More specifically, the present invention relates to an electric motor comprising one or more diametrically disposed coils placed at a stator and two or more permanent magnets placed on a disk-type rotor. Background technique [0002] Rotary electric motors are well known and have been widely used for many years now for converting electrical energy into mechanical energy. A typical electric motor includes a rotor and a stator. [0003] The rotor is the moving part of the motor, and it includes the turning shaft that transmits the rotation to the load. A rotor typically has a conductor placed within it that carries an electrical current that interacts with the magnetic field of the stator to create the force that turns the shaft. In another alternative, the rotor comprises permanent magnets, while the conductors are arranged at the stator. [0004] Correspondingly, the stator is the stationary pa...
