Variable Frequency Drive Motor

VF motors control their speed by adjusting the power frequency through a frequency converter. Variable Frequency Drive Motor is more wide in speed range, are more energy-efficient, and have smaller starting impact compared to traditional motors,which enables precise matching of speed requirements with different loads.
1. Traditional factors of VF Motors
By changing the input frequency, the speed can be continuously adjusted from 0 to several times the rated speed, meeting the precise control requirements under various operating conditions.
The motor automatically reduce energy consumption, generally saving 10% -40% more energy than traditional motors.
Adopting a soft start mechanism, the starting current is only 1-2 times the rated current, avoiding the impact of 3-5 times the rated current on the power grid and mechanical structure caused by traditional motor starting.
The Variable Frequency Drive Motor enhanced cooling system such as built-in cooling fans allows it to withstand 1.5-2 times the rated load in a short period time, which adapts to larger load fluctuations.

2. Application scenarios and examples in lifting, metallurgy, and heavy-duty handling 1 Enhancement: Precise control of enhancement and operation speed
There are extremely high requirements for improving the smoothness of motor start stop and speed controllability of equipment to prevent swinging or impact during heavy lifting.
Typical applications: The lifting mechanism and trolley operating mechanism of bridge cranes and tower cranes.
Example: Port container gantry crane (gantry crane).
A gantry crane has to be enough to lift, move, and accurately place containers of from 20 to 40 tons, from trucks or ships. By using Variable Frequency Drive Motor, these cranes can slowly accelerate from low speed during lifting to avoid swinging caused by sudden lifting. During the movement, the speed can be adjusted according to the distance (low speed at close range, high speed at long distance). During descent, low-frequency braking achieves a "slow descent" to prevent the container from colliding with the ground. In addition, during light load return (empty hook operation), the motor automatically increases speed to improve work efficiency. Compared to traditional motor-driven gantry cranes, each crane can save approximately 80 to 120 kilowatt hours of electricity per day.
