Morgan(Kollmorgen)of industrial drives division, has produced BR210, BR310, BR510 a total of 41 specifications ofthe three series of brushless servo motor and servo 1989, launched a new series designed solely doped Jian Pirates(Goldline)permanent magnet AC servo motor, including the B(small inertia), M(Middle Inertia)and EB(explosion proof)three categories, 10,20,40,60,80 five frame sizes, each of 42 categories of specifications, all using NdFeB permanent magnet, torque range of ~ , a power range of ~ the drive has BDS4(analog), BDS5(digital type, with position control)and the Smart Drive(digital type)of three series, the maximum continuous current of Series represents contemporary art in permanent magnet AC servo 39。s Inland formerly a division of Kollmorgen abroad, now merged into the AEG, the production of DC servo motors, DC torque motor and servo amplifier is BHT1100, 2200,3300 three frame sizes of 17 kinds of specifications of SmCo permanent magnet AC servo motor and eight Alsthom Group factory in Paris Parvex LC series(long form)and GC series(short)14 AC servo motor specifications, and production AXODYN series of former Soviet Union for the CNC machine tools and robots servo control developed two series of AC servo ДBy series uses ferrite magnets, there are two frame sizes, frame sizes are 3 for each core length, each with two winding data, a total of 12 specifications, a continuous torque range of 7 ~ series uses rare earth permanent magnet, 6 frame size 17 specifications, the torque range is ~ , supporting the 3ДБ recent years, Panasonic has introduced the alldigital AC servo system based MINAS series, in which permanent magnet AC servo motor with MSMA series of small inertiatype, power from ~ 5kW, a total of 18 kinds of

recent years, alldigital AC servo motor and drive system, which FAGA AC servo motor series of CSM, CSMG, CSMZ, CSMD, CSMF, CSMS, CSMH, CSMN, CSMX a variety of models, the power from 15W ~ often used(Powerrate)This prehensive index as the servo motor quality factor, measuring a variety of AC and DC servo motor contrast and dynamic response performance stepper motor power, said the rate of change(rated)torque and rotor inertia rate is calculated by power analysis, the permanent magnet AC servo motor technology indicators for the United States ID, Goldline Series is the best, followed by Germany39。s Siemens in IFT5 of the servo motor servo motorAC servo motor stator phase structure is essentially singlephase capacitor induction motor stator is equipped with 90 176。 difference between the two locations each winding, one field winding Rf, it is always connected to the AC voltage Uf。anotheris the control winding L, link control signal voltage , the two AC servo motor servo motors, also known servo motors are usually made of squirrelcage rotor, but in order to make the servo motor has a wide speed range, the mechanical properties of the linear, no “rotation” phenomenon and the rapid response of the performance, it is pared with ordinary motor should bewith the rotor resistance and a small moment of inertia of these two structure is currently used more often in two forms: one is the use of high resistivity conductive material made of high resistivity conducting bar of squirrel cage rotor, in order to reduce the rotational inertia of the rotor, rotor do slender。otherOne is made of aluminum alloy hollow cupshaped rotor, Beibi thin, only , in order to reduce the reluctance of magnetic circuit, to be placed inside the hollow cupshaped rotor fixed cupRotor moment of inertia is small, responsive, and smooth operation, so it is widely servo motor in the absence of control voltage, the stator field windings, only the magnetic field pulse generated by the rotor a control voltage, the stator generates a rotating magnetic field, rotating magnetic field along the direction of the rotor rotation, in the case of constant load, the motor speed with the size of the control voltage changes, when the control voltage of the opposite phase, the servo motorwill be working principle of AC servo motor with split phase single phase induction motor although similar, but the former is much greater than the latter of rotor resistance, so the induction motor servo motor, pared with standalone, there are three significant features: 1, high starting torqueAs a large rotor resistance, the torque curve shown in Figure 3, curve 1, with ordinary asynchronous motor torque curve than 2, a marked will enable the critical slip S0 1, so that not only the torque characteristics(mechanical properties)is closer to linear, and has a larger starting
