When the load of fans and pumps varies significantly, constant operation of the motor at full speed leads to energy losses.
The three-phase asynchronous motor with frequency regulation together with the converter provides stepless speed variation, allows the equipment to operate according to actual demand and contributes to energy saving and control automation. YVF2 engines, for example, have a squirrel cage rotor, are reliable in operation and easy to maintain.
Independent axial fan provides efficient cooling at different speeds; cooling method - IC416. The range 5–50Hz is for constant torque operation, 50–100Hz for constant power operation, which covers most industrial drives.
The series is used in the light, textile, chemical, metallurgical industries, lifting equipment and machine tool industries. Combined with high-precision sensors, high-precision feedback control is possible to meet the speed and accuracy requirements of automated lines.
