Description

Technical Field

[0001] The present invention belongs to the technical field of electromagnetic levitation motors, and in particular relates to a method, system and device for reminding an electromagnetic levitation motor of abnormal operation. Background Art

[0002] The motor is the most common and commonly used "eternal companion" that humans can never leave. It is a human dream to make the motor rotor levitate, but the cost of magnetic levitation is too high. Usually, in a magnetic levitation motor, the volume of the magnetic levitation bearing accounts for 60%, and the controller of the magnetic levitation bearing is expensive and complicated. Magnetic levitation motors are expensive luxury goods. Traditional motors have bearings, which are already commonplace. However, in special circumstances, it is not allowed or hoped that the friction force is as small as possible, and magnetic levitation becomes a necessary technology. For example: energy storage flywheels, magnetic levitation trains, all-electric aircraft turbine engines, ship hydraulic propulsion, ultra-low noise submarine drives, ocean tidal power generation, nuclear power, space and ultra-high-speed applications, etc. The natural electromagnetic magnetic levitation motor is a relatively new type of motor. It adopts a suitable pole slot combination. Without adding any sensors and controllers, it can realize radial natural dynamic electromagnetic magnetic levitation and axial passive magnetic levitation by combining the motor windings in series and parallel, and cooperating with the core segmentation.

[0003] At present, the electromagnetic magnetic levitation motor will produce a certain amount of jitter during normal operation, and it will also produce a certain amount of jitter during abnormal operation. It is impossible to distinguish from the naked eye whether the jitter generated by the electromagnetic magnetic levitation motor is normal or abnormal, and then the electromagnetic magnetic levitation motor cannot be repaired in time, resulting in damage to the electromagnetic magnetic levitation motor. In severe cases, it may cause casualties and significant economic losses. Summary of the invention

[0016] Among them, the determined ordered element sequence M b Isn't it very flat? The steps are as follows:

[0017] Determine the ordered sequence of elements M b Is the deviation between any random value and the comprehensive mean less than or equal to A?

[0018] If it is less than or equal to A, it is flat;

[0019] If it is not less than or equal to A, then get the ordered element sequence M again b ;

[0020] The analytical ordered element sequence M c The maximum value and Q a The steps to determine whether the jitter is normal are as follows:

[0021] Determine M c The maximum value and Q a Is the deviation less than h?

[0022] If it is less than h, and several consecutive values ​​around it are less than Q a , it is determined to be abnormal jitter, otherwise it is normal jitter.

[0023] Furthermore, the ordered element sequence M a The values ​​in the array are moved and balanced to form an ordered sequence of elements M. b The steps are as follows:

If it is less than or equal to A, it is flat; if it is not less than or equal to A, a new ordered element sequence M is obtained. b In order to avoid the situation where a certain jitter is not a normal jitter, the ordered element sequence M a Move the values ​​of the ordered sequence M to a balanced state. b Perform equalization on the value and determine if it is very flat to ensure normal jitter.

[0054] Step T3: When the chip 7 is asleep, obtain the jitter value and store it in the ordered element sequence M cWhen the chip 7 is asleep, as long as the jitter pauses, it immediately receives the jitter value in the sensing element 6 and obtains an ordered element sequence M. c The jitter at this moment is higher than the critical jitter of the sensing element 6. Since the sensing element 6 can trigger a pause after detecting a jitter higher than the critical value, and report the jitter to the chip 7, the jitter at this moment may be normal jitter.

[0055] Step T4: Parse the ordered element sequence M c The maximum value and Q a The correlation between the analytic ordered element sequence M is used to determine whether it is normal jitter. c The maximum value and Q a The steps to determine whether it is normal jitter are as follows: Determine M c The maximum value and Q a Is the deviation less than h? If it is less than h, and several consecutive values ​​around it are less than Q a , it is determined to be abnormal jitter, otherwise it is normal jitter.
