Abstract
Title: A MOTOR WITH SMALL STATIC TORQUE Abstract The invention relates to a motor with small static torque, belonging to the technical field of motor manufacture. The motor with small static torque comprises a stator and a rotor arranged in the stator, the rotor comprises a rotor shaft and a yoke fixed on the rotor shaft, and a magnetic ring is fixed outside the yoke and is magnetized obliquely. The motor has simple structure and little current shock to power supply circuit, solving the problems of the prior art that a motor has large starting torque and strong current shock to the power supply circuit, and the structure of the motor is complex, etc.
Description
Description A MOTOR WITH SMALL STATIC TORQUE Technical field The invention relates to a motor with small static torque, belonging to the technical field of motor manufacture. Background art In the prior art, a rotor structure generally comprises a rotating shaft, a yoke fixed on the rotating shaft and a plurality of magnetic steels evenly distributed outside the yoke, and the magnetic steels are fixed to the yoke by bonding or other ways. A motor with above structure has the problems of large starting torque having strong current shock to the power supply circuit of the motor and complex structure. Summary of the invention The object of the invention is to provide a motor with small static torque having little current shock to the power supply circuit, solving the problems of the prior art that a motor has large starting torque and strong current shock to the power supply circuit, and the structure of the motor is complex, etc. The above technical object of the invention is realized by the following technical scheme: the motor with small static torque comprises a stator and a rotor arranged in the stator, the rotor comprises a rotor shaft and a yoke fixed on the rotor shaft, and a magnetic ring is fixed outside the yoke and is magnetized obliquely. The invention uses the magnetic ring to replace magnetic steels, simplifying the structures of the rotor and the motor and reducing the static torque of the motor and accordingly further reduces the starting toque and the staring current of the motor. The wall thickness of the magnetic ring is one third to one haft of the yoke.The magnetic ring has the same height with the yoke. Therefore, the invention has the advantages of simple structure, little current shock to power supply circuit, etc. Brief description of the drawings Figure 1 is a schematic diagram of the assembly structure of the invention; Figure 2 is a schematic diagram of the external structure of the rotor of the invention; and Figure 3 is a sectional view of the rotor of the invention. Detailed description of the embodiment The invention is further described by combining the following embodiment and drawings Embodiment 1: referring to figure 1, figure 2 and figure 3, the motor with small static torque comprises a stator 1 and a rotor 2 arranged in the stator, the rotor 2 comprises a rotor shaft 3 and a yoke 4 fixed on the rotor shaft 3, a magnetic ring 5 is fixed outside the yoke 4, the magnetic ring 5 has the same height with the yoke 4, the magnetic ring 5 is magnetized obliquely (referring to magnetic lines 6 in figure 2), and the wall thickness of the magnetic ring 5 is one third of the yoke.
