Embodiment Construction

[0053] Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers may be used throughout the figures to refer to the same or like parts.

[0054] Figure 4 It is an exploded perspective view showing a motor applicable to an embodiment of the present invention or a drive motor 1 for an electric vehicle. specifically, Figure 4 An embodiment of a field coil electric machine 1 is shown.

[0055] The motor 1 may include a stator 10 and a rotor 20 . The rotor 20 rotates relative to the stator 10 through electromagnetic interaction with the stator 10 .

[0056] The stator 10 may include a stator core 11 . Also, the stator 10 may include stator coils 12 to form magnetic flux. The stator coil 12 is wound around the stator core 11 . Thus, the stator 10 may be an electromagnet.

[0057] The rotor 20 may be rotatably placed within the stat...

Abstract

The invention provides a rotor and motor and / or electric vehicle driving apparatus including the same. The motor includes a plurality of tooth bodies extending from a rotor core. A pole shoe extends from an end of at least one tooth body at opposite sides where both sides of the pole shoe have a curved outer part opposite to each other and asymmetric to each other in that a radius of curvature of the curved outer part of the one side of the pole shoe that is in a rotational direction of the rotor has a smaller radius than a radius of curvature of the other side of the pole shoe that is not in the rotational direction of the rotor.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2012-0123066 filed on Nov. 1, 2012, the contents of which are hereby incorporated by reference as if fully set forth herein. technical field [0003] The invention relates to a rotor and a motor comprising the rotor. Furthermore, the present invention relates to an electric vehicle drive device and an electric vehicle including the electric vehicle drive device. More specifically, the present invention relates to an electric motor or electric vehicle drive apparatus including a field winding rotor. Background technique [0004] Typically, a vehicle is powered by an engine. Different carbon-based fuels such as petrol and diesel are used to drive the engine. As a result, a large amount of carbon gas is emitted. For this reason, many studies have been conducted on electric vehicles or hybrid vehicles using batteries in order to reduce the amount o...
