Stator tooth where energization winding is torque winding there are the phase winding when overlapping region, is enabled with torque rotor tooth group,
The torque winding provides the electromagnetic torque of driving rotor rotation；Stator tooth and suspending power rotor tooth are completely right where energization winding
Qi Shi, enabling the phase winding is levitation force winding, and the levitation force winding provides suspending power for rotor；Motor work it is any when
It carves, there is the conducting of four phase windings, and at most have phase winding conducting on each stator tooth, being connected in winding has a phase as torque
Winding, remaining three-phase is as levitation force winding；When motor works, torque winding is every 7.5oCarry out a commutation；In an electricity
In period, the conducting width of single-phase levitation force winding is 22.5o, the commutation position of three-phase levitation force winding is along successively phase counterclockwise
Poor 7.5o。
Technical solution of the present invention is also: motor uses the working method of short magnetic circuit excitation, according to " magnetic resistance minimum principle ",
The magnetic line of force that torque winding generates forms closed circuit between stator tooth where torque winding and torque rotor tooth group, single-phase outstanding
The magnetic line of force that buoyancy winding generates is forming closed circuit between stator tooth and suspending power rotor tooth where the phase winding, due to turning
It interlinks between square winding and levitation force winding, between levitation force winding and levitation force winding there is no the magnetic line of force, to realize
The decoupling control of torque and suspending power.
Technical solution of the present invention is also: when motor works, the face of stator tooth and nipper and rear tooth where torque winding
Area changes with the change of rotor position angle, therefore nipper and rear tooth will receive size and Orientation with rotor position angle variation
Electromagnetic torque and suspending power.
Technical solution of the present invention is also: due to the positive area of stator tooth and suspending power rotor tooth where levitation force winding
Remain constant, therefore each phase levitation force winding is capable of providing size and Orientation and does not become with the variation of rotor position angle
The stable suspersion power of change, and torque will not be generated；Three-phase levitation force winding can generate stable asymmetric suspending power.
The method have the benefit that: short magnetic circuit excitation is used, the magnetic line of force is not present between energization winding and interlinks, it is real
The decoupling control of torque and suspending power, the power loss for reducing motor and control difficulty are showed；Using piecemeal rotor structure, when
When some torque rotor tooth group or suspending power rotor tooth damage, dismounting replacement can be carried out, the service life of motor is increased；
Rotor overall structure is similar to cylindrical body, can be effectively reduced windage, liquid resistance, reduces power of motor and be lost and enhance motor
Operation stability；Every phase winding bridges two stator tooths, reduces the number of switches controlled when commutation.

Specific embodiment
The present invention includes 3 three parts of stator 1, air gap 2 and rotor；The stator 1 is equipped with stator tooth 11 and winding 12, described
Stator tooth 11 has 16, and the winding 12 has 16 phases, respectively A phase-P phase, and every phase winding 12 is made of two coils, every phase around
Group 12 two coils rotating around on two adjacent stators teeth 11 and on two stator tooths 11 around on the contrary, each stator
There are two the coils from different phase windings 12 on tooth 11；The rotor 3 includes support construction 31, torque rotor tooth group 32 and hangs
Buoyant rotor tooth 33, there are three the torque rotor tooth groups 32, and each torque rotor tooth group 32 includes a nipper 321 and one
Tooth 322 afterwards, there are three the suspending power rotor tooths 33, and the torque rotor tooth group 32 and suspending power rotor tooth 33 interlock at equal intervals
Ground is fixed in support construction 31；Air gap is equipped between the stator 1 and rotor 3.
Rotate the realization of driving: definition is counterclockwise the positive direction that rotor 3 rotates, when motor works, the torque
Winding 121 is followed successively by " A phase-L phase-G phase-B phase-M phase-H phase-C phase-N phase-I phase-D phase-O phase-J phase-E phase-P phase-K phase-F
The cycle period that phase ", i.e. torque winding 121 are powered is 120o；After torque winding 121 is powered, anticlockwise electromagnetism is generated
Torque pulls rotor 3 to realize rotation counterclockwise.
The realization of suspension: when motor works, any time has three-phase windings 12 to be used as levitation force winding 122, logical at one
In electric cycle period, levitation force winding 122 be followed successively by " C phase, I phase, N phase-D phase, I phase, N phase-D phase, I phase, O phase-D phase, J phase,

122 place stator tooth 11 of levitation force winding and the positive area of suspending power rotor tooth 33 remain constant, therefore walk at one
In elongation, each phase levitation force winding 122 can provide size and Orientation not to be changed steady with the variation of 3 position angle of rotor
Determine suspending power, and torque will not be generated, three-phase levitation force winding 122 generates stable asymmetric suspending power after being powered；Torque around
After group 121 is powered, can also suspending power be generated to torque rotor tooth group 32, due to 121 place stator tooth 11 of torque winding and nipper
321 and the positive area of rear tooth 322 change with 3 position angle of rotor, therefore nipper 321 and rear tooth 322 are by size and Orientation

Power, six of them power are constant power, other two power is the power of variation.
The decoupling control of torque and suspending power is realized: as shown in Fig. 2, torque winding 121 produces according to " magnetic resistance minimum principle "
The raw magnetic line of force fully enters the nipper 321 of torque rotor tooth group 32 from 121 place stator tooth 11 of torque winding, and from rear tooth
Another phase stator tooth 11 where 322 back to torque winding 121, in 121 place stator tooth of torque winding and torque rotor tooth
Closed circuit is formed between group 32；As shown in figure 3, according to " magnetic resistance minimum principle ", the magnetic line of force meeting of the generation of levitation force winding 122
Closed circuit is formed between 122 place stator tooth 11 of levitation force winding and suspending power rotor tooth 33；As shown in figure 3, torque around
Group 121 and the magnetic line of force of levitation force winding 122 do not have common return, to relieve torque winding 121 and levitation force winding 122
Between the magnetic line of force coupling, realize the decoupling control of torque and suspending power.
Size by adjusting torque winding 121 and 122 electric current of levitation force winding can produce the outstanding of arbitrary size and direction
Buoyancy, but the curent change of torque winding 12 can have an impact torque and suspending power, and the suspension that torque winding 121 generates
Power is the power of variation, and in order to reduce control difficulty, when controlling suspending power, the electric current for not changing torque winding 121 is big
It is small, the size and Orientation of suspending power resultant force is adjusted only by adusting the size of current of three-phase levitation force winding 122.
