Motor unit model

The application of frequency conversion speed regulation in motor unit model is mainly manifested in the following aspects. (1) The frequency conversion speed regulation system can make a reasonable judgment according to the voltage and current of the motor, and detect the basic parameters of the automation device through data acquisition. (2) The frequency conversion speed regulation system will send the data to the client terminal for the first time and plan according to the current. The application value is fed back by the conversion direction between magnet and bearing in the motor, and the time and rate of frequency modulation are set. (3) In the selection of frequency converter, the investigation of chip function is usually the main reason. The frequency converter with excellent structure can be used according to the The sensing signal encodes the data and corresponds each part to the corresponding circuit module. (4) If the resistance is parallel in the motor, the frequency converter can assemble the discrete parts and analyze the data transmission results of the client terminal in order to reflect the equivalence of the resistance value and meet the requirements of energy saving.

Direct torque control technology.

After the wide application of vector control technology, a new type of high performance variable frequency speed regulation technology - direct torque control (DTC).) was born in Germany. Compared with vector control, direct torque control (DTC) technology has more optimized performance. It adopts electronic magnetic field orientation and does not need to decoupling the current. It can directly control the magnetic flux and torque of the motor, so as to obtain faster torque response.
