  • Patent number: 8753096
    Abstract: A compressor overload protection device utilizes a first electrode of an electric connector to electrically connect a first OLP overload protection loop that is electrically connected to a first power line of an external power source. In addition, a second OLP overload protection loop is connected to a second electrode and a third electrode of the electric connector, and a capacitor is electrically connected between the third electrode and the first electrode. When the operation of the compressor is overloaded, the first and second OLP overload protection loop can provide proper protection mechanism with respect to the first power line and the second power line to prevent a motor of the compressor from being overheated and damaged, and the electrodes of the electric connector can be effectively prevented from exploding.

  • Patent number: 8648518
    Abstract: A power driven component inside a compressor is disposed with a stator and rotors. The stator has an iron core in a circular ring and stator coils in a tightly wound manner. A vertical interval is formed between adjacent stator coils. A cover body is formed on the stator and a shield member that is formed with an upper portion along each stator coil and bending curve portions at two sides of the upper portion. Each bending curve portion is extended toward the interval from the upper portion. A sealed cover portion is connected between the bending curve portions of the upper portion and correspondingly seals each interval to reduce noise of the compressor and oil circulation rate.

  • Publication number: 20130088113
    Abstract: A motor having more magnets on effective area of the rotor includes a stator, a rotor and a rotation shaft, the rotor has a plurality number of rotor magnetic poles, a magnet is installed inside each of rotor magnetic pole, and a concave arc is on the outer side of each magnet and forms the first, the second and the third surfaces near inside of each magnet. The concave arc connects to the first and the third surfaces with a connecting plan respectively, each connecting plan nears the periphery surface of the rotor. The motor has more magnets on the effective area of the rotor for higher motor efficiency.

  • Publication number: 20130089443
    Abstract: A power driven component inside a compressor is disposed with a stator and rotors. The stator has an iron core in a circular ring and a plurality of stator coils in concentrated winding manner. An interval vertically passing through is formed between adjacent stator coils. A cover body is formed on the stator and a shield member that is formed with an upper portion along each stator coil and bending curve portions at two sides of the upper portion. Each bending curve portion is extended toward the interval from the upper portion. A sealed cover portion is connected between the bending curve portions of the upper portion and correspondingly seals each interval to reduce noise of the compressor and oil circle rate.
