Description

ELECTRIC MACHINE WITH D IFFERENT CONFIGURATIONS IN THE PLANE OF STATOR COILS

TECHNICAL FIELD

[0001] The present disclosure relates generally to an electric machine. In particular, the present disclosure relates to an electric machine having a plane or part of a plane of a stator coil at an angle with a direction of a motion of a moving portion relative to a stationary portion.

BACKGROUND

[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

[0003] Several electric device exist that have been designed to convert electrical energy to mechanical energy and vice-verse. Most electric devices indicative of motors and generators use the interaction between magnetic fields of two or more components to convert energy from one form to another. In most such devices, a stationary portion or stators is wrapped with one or more sets of stator coils. When an electric current is passed through the stator coils, a magnetic field is produced. Such devices also include one or more moving portions or rotors containing one or more magnetic portions that interact with the magnetic field produced by the stator coils to produce motion. In other examples, motion of the rotor is used to generate electricity by causing the magnetic field of the rotor to interact with the set of stator coils. The stator coil, stator and the rotor are suitable arranged based on use requirements.

[0004] However, existing arrangements underutilize the energy conversion capabilities. Specifically, existing arrangement underutilize the magnetic flux produced in the radial direction, leading to smaller weight to power ratio and volume to power ratio.

[0005] W02012045121A1 discloses an electromagnetic machine having an inner and outer stator, and a rotor with a plurality of magnets embedded in the rotor. The plurality of magnets are configured such that the orientation of the magnetic polar axis of each magnet is tangential to the direction of rotation of the rotor and the magnetic polar axis of each magnet is opposite to the direction of the magnetic polar axes of the adjacent magnets to provide radial magnetic fields. [0006] US9647520B2 having an annular rotor, and an outer and an inner stator that are connected to each other in parallel, wherein magnetomotive force of the inner stator is smaller than a magnetomotive force of the outer stator such that current is not reduced due to an increase of inductance and the magnetomotive force of the outer stator to be mainly driven is significantly reduced.

[0007] US9692267B2 discloses a double stator switched reluctance rotating machine having an annular rotor, an outer stator, and inner stator and a structure where a bolt fastening hole passing through the rotor in an axial direction is provided at a position based on magnetic characteristics of the inner and outer stators. The rotor also includes an annular yoke portion having a first and second salient pole that protrude outward and inward from the yoke portion, whereon the bolt fastening hole is provided.

[0008] US4501980A discloses an electric motor comprised of laminated, coaxial, annular, inner and outer stators with an annular rotor coaxially positioned between the stators. The stator may have coils wrapped about corresponding, angularly spaced apart pole pieces of the inner and outer stators to generate a magnetic flux path which passes radially outward and inward through the rotor from the inner and outer stator pole pieces.

[0009] As can be seen, the cited reference focus on arrangements of the magnetic portions of the rotors and the inner and outer stators reinforce strength of the electric devices, and do not provide adequately address the aforementioned problem related to sub-optimal utilization of magnetic flux. Particularly, the devices of the cited references suffer from eddy current losses and higher magnetic flux leakages. Furthermore, they also suffer from the drawback of requiring each coil to be energized individually to create different flux paths.

[0010] There is, therefore, a need for an electric mechanism that overcomes the drawbacks of the prior art. In particular, there is a need for an electric machine provides an arrangement that maximize force or torque on moving part of the electric machine.

OBJECTS OF THE INVENTION

[0012] An object of the present disclosure is to provide an electric device that efficiently coverts electrical energy to mechanical energy and vice-versa.

[0013] Another object of the present disclosure is to provide an electric device that allows for development of energy efficient and sustainable infrastructure. [0014] Another object of the present disclosure is to provide an electric device that produces a moving or changing magnetic field to move the moving portion.

[0015] Another object of the present disclosure is to provide an electric device that minimizes hysteresis and eddy current losses.

[0016] Another object of the present disclosure is to provide an electric device where magnetic field produced by passing current in the first stator coils enhances the force generated from magnetic field produced by passing current in the second stator coil, thereby producing higher torque.

[0017] Another object of the present disclosure is to provide an electric device that generates one sided, short flux path magnetic field to reduces energy losses.
