The revolution of DC brush servomotor is the stationary magnetic field of permanent magnet generation by stator side, through the rotor rectified action, allows an electric current with the stator field quadrature produce turning power through the armature rotor coil.This orthogonality relation is kept automatically by brush and commutator, and therefore control is simple relatively.But there is following point:, bring the high problem of maintenance cost because the brush motor needs are often safeguarded, clear up, changed brush; Because of the temperature rise of motor or vibration all can cause the weak magnetic of permanent magnet or come off, cause output power of motor to descend even the accident of personal safety occurs relating to; Because the weak magnetic of permanent magnet and the spark of commutator are difficult to directly start to walk from inactive state; With the spark owing to commutator, some specific area (as explosion-proof) can not use and be difficult to speed-raising.
The permanent magnet of alternating-current brushless servomotor is fixed on the rotor, and allows electric current flow through stator coil.The function of commutator is replaced by the position detecting device and the electronics phase changer of permanent magnet.Its principle is identical with the DC servo machine, thus its control than above-mentioned DC generator complexity, the control difficulty is big, the cost height simultaneously also exists high temperature or vibration to cause the weak magnetic of permanent magnet or the problem that comes off.In addition, because the weak magnetic of permanent magnet, capacity motor is subjected to certain limitation, and the centrifugal action of rotor makes speed-raising be subjected to certain limitation.
The utility model content
The purpose of this utility model provides a kind of controller that is used to control three-phase alternating-current motor frequency conversion servo system that overcomes above-mentioned shortcoming, can control position, rotating speed, acceleration and the output torque of motor easily by programming.
According to the controller that is used for the control of conversion servo system of the present utility model is the frequency change servo controller that is used to control the three-phase alternating current squirrel-cage motor, and it comprises major loop part, power unit and control loop part.
On the other hand, described power unit is a Switching Power Supply, is used for providing power supply to control main board; Described major loop partly comprises rectification, filtering, inverter circuit; With described control loop (cpu motherboard) is partly integrated system level chip SOC (System on a Chip), intelligent semi-conductor power model ASIPM (or the system-level semi-conductor power module of SIPM) and imput output circuit arranged.
By realizing that the utility model is used for the controller of control of conversion servo system, adopt 32 dedicated cpus that motor is carried out full-digital control, and special-purpose QMCL (the QuickMotion Control Language) language of employing, make that the programming of control program is simple, can make motor with extremely low rotating speed operation.And, realized that functions such as subminaturization, multifunction, telecommunication have also greatly improved every performance index of system owing to used the integrated design of SOC+ASIPM or SOC+SIPM and the fusion of simulation and digital technology.
