YVF2 series energy saving motor follows Chinese standard, GB755-2008 Rotating electrical machines-Rating and performance , which equals to IEC60034-1:2004.
With the rapid development of power electronics technology and new semiconductor devices, AC speed regulation technology has been continuously improved and improved. Gradually improved frequency converters are widely used in AC motors with their good output waveform and excellent performance to price ratio. For example, large electric motors and small and medium-sized roller motors used in steel mills for rolling, traction motors for railways and urban rail transit, elevator motors, lifting motors for container lifting equipment, motors for water pumps and fans, compressors, and motors for household appliances have all successively used AC variable frequency speed control motors, and have achieved good results.
The use of AC variable frequency speed regulation motors has significant advantages over DC speed regulation motors,such as
1. Easy speed regulation and energy-saving.
2. The AC motor has a simple structure, small volume, small inertia, low cost, easy maintenance, and durability.
3. Capacity can be expanded to achieve high speed and high voltage operation.
4. It can achieve soft start and fast braking.
5. Spark free, explosion-proof, and strong environmental adaptability.
The social benefits of domestically produced high-voltage frequency conversion devices are significant, mainly in terms of energy conservation, thereby saving resources and reducing environmental pollution. Eliminate the starting shock of the motor and its impact on the power grid, and reduce the failure rate of the motor and equipment. Improve control accuracy and automation level. The economic benefits of YVF2 series energy saving motor are also very significant.
Here is one chart of low voltage AC motor to compare fixed frequency motor and variable frequency motor.
