Synchronous magnetic resistance motor and AC induction motor have identical stator structure, stator by stator core 1 and stator around
Group 2 composition, stator winding 2, in the case of applying sinusoidal ac, produces the rotating excitation field of alternation in air gap.
AC induction motor rotor mostly is conventional cage-shaped structure, is made up of rotor core and cast aluminium closed-loop path, this kind
Structure can produce the loss of 24%.Magnetic resistance motor rotor is different from induction machine, uses innovative magnetoresistive structures (as shown in Figure 2),
Rotor core is washed into difform does not has, every magnetic grid, the closed-loop path that casting aluminium material is constituted, and therefore synchronous magnetic resistance motor can
To make rotor zero loss, therefore it is readily devised IE4 high efficiency motor.
The operation principle of a kind of synchronous magnetic resistance motor that the present invention provides is:
Owing to magnetoresistive structures rotor has direction each opposite sex feature, different directions pcrmeability is different in other words, and Fig. 2 is 4
The rotor structure of electrode structure, has 4 high, 4 low pcrmeability axles, and high magnetic permeability means high magnetic conduction ability, it is understood that for
High inductance, contrary low magnetic permeability has contrary characteristic.Magnetic resistance is the inverse of pcrmeability, is magneto-resistor, Gao Ci in technical term
Resistance can be understood as low inductance, in order to realize vector controlled, therefore high magnetic permeability axle is demarcated as d axle 33, contrary high magnetic resistance axle mark
It is set to q axle 32.When stator winding 2 applies sine voltage, just producing rotating excitation field in motor gas-gap, rotor can be forced to lead to height
Magnetic d axle 33 aligns, and to form minimum magnetic loop, then just creates torque in stator, rotor airgap, and motor is just turned over
?.
Synchronous magnetic resistance motor and AC induction motor have identical stator structure, do not do stator too
Many descriptions, will introduce the design every magnetic grid 31 below.
Every magnetic grid 31 angle-determining, require first to determine the number of poles of motor, the namely angle of d, q axle according to the technology of motor
Degree, uses 4 pole designs in this example, therefore the mechanical angle of d, q axle is 45 degree.
Determining every magnetic grid 31 number of plies, the design of synchronous magnetic resistance motor uses FEM(finite element emulation software), by this software
Torque Output simulation can be carried out to each every magnetic grid 31, according to design of electrical motor torque index by FEM software may determine that every
The layout of magnetic grid 31 and arrangement mode (i.e. the number of plies), this example synchronous magnetic resistance motor be 15kw, 1500 revs/min, nominal torque is
95.5 Ns. rice, use 4 layers and design every magnetic grid 31.
Determining every magnetic grid 31 shape, using FEM software to keep the constant amplitude of electric current when emulating, angle is to produce the most every time
Big torque, is gradually increased the width every magnetic grid 31, and torque starts to increase from initial value, and reason is when q axle 32 magnetic resistance increases sharply
Time, d axle 33 magnetic resistance is not changed in, and every magnetic grid 31 width, during increasing, the torque pulsation of motor is also in change, when every magnetic grid
After 31 width reach certain value, the torque pulsation of motor tends to constant, minimum, and being every magnetic grid 31 width now most preferably sets
Meter.Also to optimize the radian design every magnetic grid 31 to obtain less cogging torque and torque pulsation, consider that motor turns simultaneously
