Problems solved by technology

This leaves another limitation on improving the efficiency of the motor at high temperature
[0020] At the same time, it is well known that a single-phase induction motor should essentially always run slower than a preset synchronous speed in order to be able to generate induced torque

Embodiment Construction

[0098] In the following, reference will be made to the attached Figure 3 to Figure 15 A preferred embodiment of the electric machine according to the invention is set out in detail. For the sake of brevity and convenience of explanation, it will be described that an inner rotor type motor is provided which rotates inside a stator, but the motor of the present invention is not limited to the inner rotor type motor.

[0099] The motor according to the present invention is constructed by the same method as conventional induction motors in the prior art, wherein the rotor 120 [w9] starts running by induction torque. That is, if image 3 As shown, the motor adopts the structure of an induction motor, including a rotor 120 having slots 121 and conductive rods 122, a stator coil 112 [w10] and a stator coil 114 [w11] (hereinafter referred to as "coils") for rotation of the motor , and capacitor 115 [w12]. Therefore, any description below will not detail the same structure between ...

Abstract

The present invention provides a motor, comprising: a stator including a coil wiring portion to which power is supplied; a rotor, which includes conductive bars, flux barriers, and permanent magnets, and rotates through an interactive electromagnetic force between the conductive bars, flux barriers, and permanent magnets and the coil wiring portion of the stator; an integrated capacitor, which is electrically connected to the coil wiring portion and includes two capacitors connected to each other in parallel, an electrical switch serially connected to one of the two capacitors, and a casing on which the two capacitors and the electrical switch are securely mounted.

Description

technical field [0001] The present invention relates to a motor, and more particularly to a motor having high efficiency by minimizing power loss. The motor produces a higher starting torque and rotates at a preset synchronous speed during normal operation. Background technique [0002] In general, a single-phase induction motor consists of a stator wound with main and secondary coils physically spaced 90° apart from each other, and a voltage applied directly to the main coil and indirectly (i.e., through capacitors and switches) to the secondary coil. power supply. This is because a single-phase induction motor will not start even if voltage is applied to the main coil. Therefore, starting means such as secondary coils are required to create the rotor system on the stator, thereby starting or starting the rotor. [0003] There are many types of starting devices such as split-phase starting, shield coil starting, capacitor starting, repulsion starting, etc. [0004] refe...
