Embodiment 1

[0052] combine figure 1 , figure 2 , image 3 and Figure 4 Take the opening to closing process of the magnetic levitation ventilation fan of the present invention as an example. The working process of the maglev ventilation fan includes a fan opening process, a fan working process and a fan closing process.

[0053] When the fan is turned on, the power coil 3 and the balance coil 9 are energized and generate a magnetic field, and at the same time the limiting part is closed, and the suspension part 6 is under the influence of its own gravity G and the attractive force F of the first magnet 2. 1 And the magnetic field force F formed by the magnetic field generated by the balance coil 9 2 Under the action of the resultant force, it moves toward the fixed seat 8, and the floating part 6 generates a rotational movement during the movement toward the fixed seat 8, and the impeller speed of the floating part 6 is in the process of approaching the fixed seat 8. The reaction fo...

Abstract

The invention relates to a control part for rotating speed regulation and rebalancing of a magnetic levitation ventilation fan. The magnetic levitation ventilation fan at least comprises a first fixing part, a suspension part and a fixing column, wherein the fixing column is sleeved with the first fixing part and the suspension part respectively; the control part is arranged on a base of the firstfixing part and used for realizing current control of a power coil and a balance coil; the control part completes current intensity adjustment of the power coil on the basis of rotating speed gear adjustment of the vent fan by a user and adjusts intensity of an induced magnetic field, so that the rotating speed of a rotor at the suspension part is adjusted.

Description

[0001] The present invention is a divisional application with the application number 201710411879.2, the application date is June 2, 2017, the application type is invention, and the application name is a magnetic levitation ventilation fan. technical field [0002] The invention relates to a magnetic levitation device, in particular to a control part for adjusting and rebalancing the rotation speed of a magnetic levitation ventilation fan. Background technique [0003] Magnetic levitation technology refers to a technology that uses magnetic force to overcome gravity to levitate objects. The current levitation technologies mainly include magnetic levitation, light levitation, acoustic levitation, air levitation, electric levitation, particle beam levitation, etc. Among them, the levitation technology of magnetic levitation is relatively mature. Magnetic levitation technology (electromagnetic levitation, electromagnetic suspension) is referred to as EML technology (or EMS tech...
