Description

Technical Field

[0001] The utility model relates to the technical field of magnetic force detection, in particular to a flywheel magnetic suspension magnetic force detection device. Background Art

[0002] Since the flywheel in the vertical motor with flywheel rotor structure is heavy, the structure exerts a greater bearing force on the bearings. A magnetic levitation device is designed to absorb the flywheel and offset the flywheel weight, so that the upper and lower bearings do not bear the flywheel weight, thereby reducing the flywheel bearing force of the bearings. However, the size of the magnetic force is also crucial. Regardless of the size, it will cause damage to the upper and lower bearings to varying degrees. Therefore, a flywheel magnetic levitation magnetic force detection device is proposed to solve this problem. Utility Model Content

[0018] Install the pressure sensor on the mounting frame 50, and then install the mounting frame 50 to the bottom of the mounting assembly with bolts. After the flywheel 30 is assembled in place, use the support to support the weight of the flywheel so that the pressure value of the pressure sensor 52 is 0. After a small amount of current is passed through the magnetic levitation device 20, the magnetic levitation device generates magnetic force, thereby having a magnetic attraction to the flywheel 30. Slowly loosen the support. At this time, the pressure sensor 52 can read the pressure value, and then slowly increase the current value to increase the magnetic force until the pressure value just reaches 0. Record the current size at this time, and then install the support in place. The magnetic force measurement is completed.
