So as to form closed-loop control, make the stabilization of speed of main shaft 1.
A kind of control method of above-mentioned more rail magnetos, the stator 4 in left side be the first stator in Figure of description 8, the right side
The stator 4 of side is the second stator.
Control method comprises the following steps：
Phase detecting module detects the position of permanent magnet 7 on two stators 4；
Code-disc 2 detects the position of permanent magnet 7 by the photoelectric sensor on casing, and will believe with the synchronous axial system of main shaft 1
Number control module is uploaded to, in the present embodiment, control module is single-chip microcomputer.
The all coils of one stator 4 access the electric current of equidirectional, and another stator 4 powers off, with the phase of energization stator 4
During permanent magnet 7 and coaxial coil on adjacent rotor, the stator of energization powers off, what all coils of another stator 4 were passed through
Direction identical electric current, each stator 4 it is adjacent twice be powered when the sense of current it is opposite.
All air core coils 6 of first stator access the electric current of equidirectional, while the second stator cut-out electric current, main shaft
1 rotates, when turn to the permanent magnet 7 of the adjacent rotor of the first stator it is coaxial with air core coil 6 on the first stator when, first determines
Son power-off, the second stator access electric current.When turn to the permanent magnet 7 of the adjacent rotor of the second stator with it is hollow in adjacent rotor
When coil 6 is coaxial, the power-off of the second stator, the first stator access electric current, and the sense of current is opposite with the sense of current of last time；When again
When the secondary permanent magnet 7 for turning to the adjacent rotor of the first stator and coaxial air core coil 6 on the first stator, the first stator breaks
Electricity, the second stator access electric current, and the sense of current on the contrary, simultaneously circulate successively, realize electric machine main shaft 1 with last time sense of current
It is lasting to rotate, additionally it is possible to which that realization avoids air core coil 6 from the problem of cutting magnetic induction line occur.It is coaxial in air core coil 6 and permanent magnet 7
When cut off electric current, air core coil 6 can be avoided to play magnetic conduction effect, and then air core coil 6 is avoided the occurrence of and cutting magnetic induction line occur
Phenomenon, resistance is small in rotor rotation process.The magnetic force of permanent magnet 7 is stronger, and the efficiency of motor is higher, and conventional permanent magnet motor
The magnetic force of permanent magnet 7 has an optimum value, and the magnetic force of permanent magnet 7, which is more than or less than optimum value, can all cause conventional permanent magnet motor
Efficiency reduce, and as the difference of the magnetic force of permanent magnet 7 and optimum value is bigger, efficiency reduces more.
In the present embodiment, the switching mode of electric current is as shown in the table：
。
The experimental data of the motor is as follows：
。
As seen from the above table, the efficiency minimum 93.8%, up to 99% of more rail magnetos of the application, efficiency carries significantly
Height, and be 0.1V, electric current 0.7A in motor, in the case that power is 0.07W, power is that 15KW motor brings into operation.
