Background technique

The air gap flux density of mixed excitation electric machine is generated jointly by permanent magnet and electrical excitation winding, and revolving speed (or voltage) is adjusted It is realized by the electrical excitation winding assisted required changes of magnetic field part.When electricity excitation magnetic field direction is identical as permanent magnetic field direction When, air-gap field enhancing；When electricity excitation magnetic field is contrary with permanent magnetic field, air-gap field weakens.So being encouraged by adjusting electricity The size and Orientation of magnetic winding current is not only able to achieve the control of motor-field weak magnetic, can also carry out increasing magnetic control.Composite excitation Motor not only inherits the various features such as magneto is high-efficient, torque/mass ratio is big, but also motor gas-gap magnetic field smoothly may be used It adjusts, when electric operation, has the advantages that starting torque is big, speed adjustable range is wide；When generator operation, there is wider voltage to adjust energy Power or wide scope speed constant pressure fan-out capability.The flux control means of mixed excitation electric machine are simple, direct, realize to motor gas Gap magnetic field is separately adjustable and controls.The reluctance motor of this composite excitation can be applied on fly wheel generator.Flywheel pulse hair Motor is a kind of flywheel energy storage that energy converting between mechanical is realized using the large inertia storage energy of shafting, coaxial dynamoelectric machine Device.Investment application at present or energy accumulation device for fly wheel being developed are there are two types of type: the first is energy storage and release can power etc. Grade quite, can alternately realize electronic and generating function with a motor, and the energy storage system for magnetic floating flywheel of Small And Medium Capacity is this Type, has the characteristics that compact-sized, high-efficient, is typically used as flying wheel battery；Be for second energy storage power ratio release can power it is small More than an order of magnitude, You Liangtai motor realizes electronic and generating function respectively, and large capacity alternating-current pulse generating set is this Type, with small-power, long-time storage energy, the high-power, short time releases energy, and is typically used as the large capacity pulse power, can Applied to controlled nuclear fusion test, nuclear explosion simulation, high current particle beam accelerator, high power pulsed laser, High-Power Microwave, The fields such as plasma and ELECTROMAGNETIC LAUNCH TECHNOLOGY.

The structure of common Flywheel motor-generator system is as shown in figure 13.The basic functional principle of system are as follows: when system is filled When electric, energy is provided a system to by external electrical network, the power inverter control constituted via power electronic devices and driving motor, Flywheel high speed rotation is driven, reaches and is maintained at constant high velocity operation, required energy is stored in a manner of kinetic energy, is completed from electric energy To the conversion and energy stores of mechanical energy.When pulse load needs to power, the flywheel of high speed rotation operation is treated as into prime mover Electric power generation operation is driven, the voltage and electric current for being suitble to pulse load are exported by converters, completes energy conversion Process.Electronic and generating set in Figure 13 can be replaced with composite excitation reluctance motor.

Figure 12 is the sectional view of a 12/8 pole, mixed excitation double-salient reluctance motor of three-phase, and stator and rotor are in double-salient-pole knot Structure, without winding, without permanent magnet on rotor, stator is connected using centralized winding, space with respect to the coil on tooth two-by-two, two groups of lines Enclose serial or parallel formation threephase armature winding.Stator yoke is embedded in four blocks of permanent magnetism that magnetic is tangentially rushed using high performance permanent magnetic materials Body forms motor gas-gap main field；Electrical excitation winding is placed in the stator slot adjacent with permanent magnet.For the effect for improving electrical excitation Rate realizes that lesser electrical excitation obtains biggish flux control ability, in electric machine structure between permanent magnet and electrical excitation winding There are the iron core magnetic conduction bridges of certain size.Using permanent magnet leakage field, makes the work of magnetic conduction bridge in relative saturation state, led by saturation The reasonable selection of magnetic bridge size provides additional Paralleled Magnetic Sub-path for electrical excitation winding, reaches with lesser DC excitation magnetic potential Obtain the purpose of larger air-gap flux adjustable range.

But the motor has the following disadvantages: rotor core using silicon steel sheet stack at unsuitable high speed rotation；Rotor iron loss Height, no-load loss are big；The magnetic circuit magnetic conductance of series circuit composite excitation is small, and exciting current is big, flux control narrow range；Stator core Circumferentially divide valve, stator structure intensity difference.
