China food processing motor Factory, the production of food motor series, frequency conversion is one of them.Frequency conversion motor converter can be a kind of motor, or it can be a combination, the use of frequency converter must abide by some rules, in order to play its good function.Frequency conversion motor
One, frequency conversion motor must be correctly selected frequency converter, so before normal use need to carefully read the product instructions, and in accordance with the requirements of the instructions wiring, installation and use.Note that the frequency converter device should be reliably grounded. When using the frequency converter to control the motor speed, pay attention to ventilation and cooling as well as proper load reduction to avoid the motor temperature rise exceeding the allowable value.
The impedance of power supply line of frequency conversion motor cannot be too small.When the line impedance is too small, the ac reactor should be installed between the grid and the frequency converter.It is more serious when the transformer is connected by V-shaped method. Besides installing reactors on the AC side, it is also necessary to install DC reactors on the DC side.
3. The variable frequency motor cannot be equipped with a capacitor, which will reduce the line impedance and cause overcurrent damage to the converter.
Iv. The inverter of the variable frequency motor cannot compensate the capacitance in parallel, but can series the reactor.
Five, the motor with frequency conversion motor inverter speed regulating start and stop, can not be directly operated by circuit breakers and contactors, and the application of the inverter control terminal to operate, otherwise it will cause the inverter out of control, and may cause serious consequences.
6. The inverter and the motor should not be equipped with ac contactor. If it needs to be installed, the output contactor should be closed before the inverter runs.
