YVF3 Series Variable Frequency Three Phase Induction Motor Model Description:

What is the meaning of the YVF three phase induction motor model series? for example:

YVF3-450L1-8

• “Y” stands for Y series squirrel cage induction motor;
• “VF” is actually a variable frequency speed regulation mode that can be used in V/F constant control mode
• “3” is the feature code
• “450” is the frame size
• “L1” is the core length code
• “8” is the motor poles

YVF3 Series Variable Frequency Three Phase Induction Motor Advantages:

YVF3 variable frequency electric motor can change the speed according to the load adjustment frequency. In low-voltage places, the frequency of the YVF3 series three phase induction motors can be reduced, so that the motor can start reliably. In light load places, the YVF3 variable frequency motor can be used to reduce the frequency, reduce the speed and current, and save energy. YVF3 variable frequency electric motor can change the frequency of the motor according to the work requirements to meet the required speed requirements. Of course, some working conditions also need to add a forced cooling fan to ensure the cooling of the motor at low frequency and low speed for a long time, and to prevent the motor from burning out due to excessive temperature rise.

1. YVF3 variable frequency electric motor can be continuously variable speed.

Infinite speed adjustment is from stop to maximum speed, or from maximum speed to stop, without gears, it gradually becomes faster or slower. In addition, the full DC variable frequency motor can control the motor speed and actual demand by dividing the motor speed gear into multiple gears through the inverter. However, the maximum number of gears for AC brushed motors is only 3. Wind speed adjustment cannot achieve the effect of frequency conversion.

2. YVF3 variable frequency electric motor has a long service life.

When the motor is running, the carrier frequency is about several thousand to ten thousand Hz, which makes the stator winding of the motor withstand a high rate of voltage rise, which is equivalent to the steep impulse voltage applied by the motor, which makes the motor's turn insulation Withstand a more severe test. However, the YVF3 variable frequency electric motor can work under rectified and filtered voltage, with more stable performance and longer service life.

3. YVF3 variable frequency electric motor saves more energy.

All household appliances produce harmonic voltage and current to varying degrees during the operation of the motor, so that the motor runs under non-sinusoidal voltage and current. High-order harmonics will lead to an increase in rotor copper loss, iron loss, and additional motor stator loss, the most significant of which is the team copper loss. Because the ordinary AC motor rotates at a synchronous speed close to the fundamental frequency, the high-order harmonic voltage will cut off the rotor bar with a large slip rate, resulting in large rotor loss. In addition, the extra copper consumption caused by the skin effect should also be considered. These losses apply to the additional heating of the motor, thereby reducing efficiency and output power. However, if the YVF3 variable frequency motor is used, its energy consumption can be reduced by about 20%-30%.

YVF3 Series Variable Frequency Three Phase Motor Applications:

YVF3 series low-voltage high-power variable frequency three phase induction motors are general-purpose cage-type three-phase asynchronous motors, which can be used for general variable frequency speed regulation power machinery, and are widely used in metallurgy, water supply, oil fields, ports, mines, etc.
