  • Publication number: 20140175932
    Abstract: Disclosed are a motor and a rotor thereof. Taking the distance between the two endpoints of a permanent magnet (20) of a motor rotor that are on the side away from the centre of an iron core (10) as the length L of the permanent magnet, and the distance between a line connecting the two endpoints of the permanent magnet that are on the side away from the centre of the iron core (10) and the centre point on the side of the permanent magnet that is close to the centreline of the iron core as the width H of the permanent magnet, then H/L?1/10. By adjusting the relationship between the length L and width H of the permanent magnet, the air gap magnetic density of the permanent magnet can be effectively increased, i.e. increasing the permanent magnetic flux of the rotor in the directions of the d axis and q axis. Hence, the utilization rate of the permanent magnet and the performance of the rotor can be improved without increasing the number of permanent magnets used.

  • Publication number: 20140167549
    Abstract: Disclosed is a motor rotor, comprising an iron core (10) and permanent magnets (20) provided inside the iron core (10). The iron core (10) is provided with sets of mounting grooves (30) in the peripheral direction of the iron core, each set of mounting grooves (30) comprising two or more mounting grooves (30) provided intermittently in the radial direction of the iron core (10). There are sets of permanent magnets (20), the individual permanent magnets (20) of each set of permanent magnets (20) correspondingly being embedded into the individual mounting grooves (30) of each set of mounting grooves. Disclosed is a motor comprising the above-mentioned motor rotor. The motor rotor increases the magnetic reluctance torque of the motor rotor and thus increases the output torque of the motor and the efficiency of the motor.
