Description

Technical Field

[0001] The utility model relates to the technical field of brushless motors, in particular to a magnetic suspension motor used for shavers and electric hair clippers. Background Art

[0002] Currently, most shavers and electric hair clippers still use brush motors as power, and the motor shaft and eccentric mechanism are used to make the cutter head reciprocate. Brush motors have become major technical problems due to mechanical steering reasons and motor life issues. Current technology can only extend the life of the motor as much as possible, but cannot fundamentally solve the problem. At the same time, elastic materials are used to make the cutter head reciprocate. This method has the risk of elastic material breakage, thereby reducing the practicality of the motor. Utility Model Content

[0005] Preferably, the coil upper frame and the coil lower frame are plugged and fixed to each other.

[0006] Preferably, a stator magnet group is fixedly connected to the magnet conductive sheet.

[0007] Preferably, the stator magnet groups are located on both sides of the rotor core.

[0008] Preferably, two ends of the coil upper frame and the coil lower frame are respectively fixedly connected with a first magnetic conductive ring and a second magnetic conductive ring.

[0011] The utility model provides a magnetic levitation motor for shavers and electric hair clippers, which has the advantages that: the device can change the point magnetic field generated by the first coil and the second coil by turning on and off the power of the first coil and the second coil, so that the rotating iron core performs deflection motion, and continuously changes the power polarity of the coil to make the rotation reciprocate, thereby driving the rocker to perform reciprocating motion, changing the working mode of the reciprocating motion, not only prolonging the service life of the device, but also improving the practicability of the device.

[0019] See also Figure 1-3 The utility model provides an embodiment: a magnetic suspension motor for a shaver and an electric hair clipper, comprising a first magnetic conductive ring 1, a first coil 2, a second coil 3, a second magnetic conductive ring 4, a coil upper frame 5, a coil lower frame 6, an upper frame bearing 7, a lower frame bearing 8, a rotor core 9, a rotor central axis 10, a stator magnet group 11, a magnet magnetic conductive sheet 12, a first bearing sleeve 13 and a second bearing sleeve 14, the rotor core 9 is fixedly connected with the rotor central axis 10, the two ends of the rotor central axis 10 are respectively fixedly connected with the first bearing sleeve 13 and the second bearing sleeve 14, the first bearing sleeve 13 and the second bearing sleeve 14 are respectively sleeved and fixed with the upper frame bearing 7 and the lower frame bearing 8, the upper frame bearing 7 and the lower frame bearing 8 are respectively sleeved and fixed in the through holes opened on the coil upper frame 5 and the coil lower frame 6, and the deflection accuracy of the rotor core 9 when doing deflection movement is improved by using the provided rotor central axis 10, the upper frame bearing 7, the lower frame bearing 8, the first bearing sleeve 13 and the second bearing sleeve 14;

[0020] The coil upper frame 5 and the coil lower frame 6 are plugged and fixed to each other, and the first coil 2 and the second coil 3 are wound around the two ends of the coil upper frame 5 and the coil lower frame 6 respectively, and the inner two sides of the coil upper frame 5 and the coil lower frame 6 work together to fix the magnet conductive sheet 12, and the magnetic field is changed by turning on and off the power of the first coil 2 and the second coil 3, thereby driving the deflection movement of the rotor core 9;

[0021] A stator magnet group 11 is fixedly connected to the magnet conductive sheet 12, and the stator magnet group 11 is located on both sides of the rotor core 9. The first magnetic conductive ring 1 and the second magnetic conductive ring 4 are fixedly connected to both ends of the coil upper frame 5 and the coil lower frame 6, respectively.

The first magnetic conductive ring 1, the first coil 2, the second coil 3 and the second magnetic conductive ring 4 are formed with hole slots, and the hole slots and the rocker fixedly connected to the rotor core 9 correspond to each other.

[0022] Specifically, when in use, first, when the first coil 2 and the second coil 3 are not energized, the attraction of the stator magnet group 11 causes the rotor core 9 to be relatively suspended, and the rocker on the rotor core 9 is in a suspended state. When the first coil 2 or the second coil 3 is energized, the rotor core 9 generates an induced magnetic field. The induced magnetic field and the magnetic field of the stator magnet group 11 act to cause the rotor core 9 to deflect. At the same time, the rocker on the rotor core 9 deflects, thereby outputting power to the outside. When the energizing polarity of the first coil 2 or the second coil 3 is changed, the rotor core 9 deflects in the opposite direction, continuously changing the energizing polarity of the first coil 2 or the second coil 3, causing the rotor core 9 to reciprocate, that is, the rocker on the rotor core 9 reciprocates.
