Abstract
A motor, a compressor and a refrigeration device are provided. The motor has a stator, a plurality of coil sets and a rotor. The stator has multiple stator teeth arranged along a peripheral direction. Every two adjacent stator teeth define a stator groove. Each coil set has multiple coils wound on the stator teeth. Each coil bypasses a corresponding stator tooth. The rotor is arranged inside the stator and has a rotor core and multiple permanent magnets. The rotor core has multiple slots. The slots are distributed circumferentially around a rotation center line of the rotor core. The permanent magnets are arranged in the slots.
