This disclosure relates to a rotor, an electric motor, and a compressor. The rotor includes a rotor core, a plurality of rare-earth permanent magnets, and a plurality of ferrite permanent magnets. The rotor core includes a plurality of core units arranged sequentially along the circumference of the rotor core. Each core unit has two first mounting slots and one second mounting slot arranged circumferentially at intervals. The first mounting slots have openings located on the outer circumferential surface of the core unit. The second mounting slots are located between the two first mounting slots and opposite to the side of the first mounting slots away from the opening. The plurality of rare-earth permanent magnets are fixed one-to-one in all the first mounting slots; the plurality of ferrite permanent magnets are fixed one-to-one in all the second mounting slots. This disclosure can improve motor performance by increasing the amount of inexpensive ferrite permanent magnets while reducing the amount of rare-earth materials used, thereby balancing motor performance and cost.
