Brushless DC compressor in micro-miniature form
A brushless DC compressor comprising a casing, a brushless DC motor, a compression device, and a driving mechanism. The casing has a left room, a right room adjacent the left room, and a lower room. The brushless DC motor is disposed in the left room, and the compression device is disposed in the right room. The driving mechanism is disposed in the lower room, including a driving gear engaging a rotor of the brushless DC motor, a driven gear engaging a hollow shaft of the compression device and driven by the driving gear; whereby refrigerant flows into a compression space of the compression device, rotating the rotor by the stator and driving the driving gear, the driven gear, then the compression device; then being discharged from a refrigerant discharge hole and an axial groove, to form a brushless DC compressor with stronger torque and greater compression efficiency.
