The utility model relates to a permanent magnet motor rotor during surface fitting, which comprises a rotor iron core, a gluing layer is distributed on the outer circle surface of the rotor iron core, a glue fixing assembly is distributed outside the gluing layer, a permanent magnet positioning ring is sleeved outside the rotor iron core, and a plurality of limiting grooves are formed in the permanent magnet positioning ring in the direction facing the rotor iron core. N/S pole permanent magnets are arranged in the limiting grooves, and the N/S pole permanent magnets are adsorbed on the outer circle surface of the rotor iron core. Therefore, equal-thickness colloids can be formed between the rotor iron core and the corresponding N/S pole permanent magnets, the bonding strength between the N/S pole permanent magnets and the rotor iron core is multiplied, unnecessary displacement is avoided, and work and operation are more stable. The shape of the limiting groove is attached to the N/S pole permanent magnet, ef
