A rotor, a motor and a compressor are provided. The rotor has multiple first punches and multiple second punches, which are stacked to form a rotor core of the rotor.

The openings divide the first punches and the second punches into a rotor yoke and multiple pole caps. The pole caps are arranged around the outer circumference of the rotor yoke. The openings extend in an axial direction of the rotor core to form a plurality of slots. Multiple magnets are arranged in the slots in a one-to-one correspondence. Each first punch includes one or more connecting ribs. Each connecting rib is disposed between adjacent two pole caps. At least two of the openings of each second punch communicate with each other.
