Ventilation fan motor supplier, precautions when installing a ventilating heater:
When installing the heater motor, pay attention to the use of appropriate screws; when wiring, be careful not to pull the core wire and sheath wire vigorously; when using, be careful not to change the voltage at will, and do not leave the motor for a long time. Use; do not use the heater motor in a corrosive environment. When ordering, please indicate the working voltage, speed, rotation direction of the heater motor, the specification and length of the lead wire, the length of the output shaft and other technical parameters. There is also the power saving principle of variable frequency motor ventilator
The power-saving principle of variable frequency motor ventilator Any production machine that uses AC induction variable frequency motor ventilator as a power transmission method, the power of the variable frequency motor ventilator is selected according to the rated load during the maximum load period. However, most of them cannot run at full load during work. The motor works at full voltage and full speed and the load is small. There will also be a lot of time for no-load operation. From the design and operating characteristics of the motor, it can be known that the efficiency of the motor is only when it runs at full load. The highest, power factor COS￠ best condition, reduced at light load, and even dropped below 0.3 at no load, causing a lot of unnecessary power loss.
