There are many kinds of mechanical equipment in the mechanical industry, and there are many kinds of motors in the electrical industry. Different types of motors are used for different functional equipment, such as variable frequency motor, ordinary motor, brake motor, electromagnetic brake motor, etc. why do some equipment use variable frequency motor instead of ordinary motor? What are the characteristics and advantages of using YVF2 variable frequency motor? Let's share with you
Features of YVF2 variable frequency motor
YVF2 variable frequency motor can change the speed according to the frequency of load adjustment, and the frequency of variable frequency motor can be reduced in low voltage area, so that the motor can be started reliably. In light load area, the frequency of variable frequency motor can be reduced, the speed and current can be reduced to save electric energy. The variable frequency motor can meet the speed requirements by changing the frequency of the motor according to the work requirements. Of course, some working conditions also require the addition of forced cooling fan to ensure the cooling of the motor in the long-term low frequency and low speed, so as to avoid burning due to the high temperature rise of the motor.

The harmonic electromagnetic noise and vibration of YVF2 inverter motor are smaller.
The vibration and noise caused by electromagnetic, mechanical, ventilation and other factors are more complex. Each time harmonic contained in the variable frequency power supply interferes with the inherent space harmonic of the electromagnetic part of the motor, forming various electromagnetic exciting forces. When the frequency of electromagnetic force wave is consistent with or close to the natural vibration frequency of motor body, resonance phenomenon will be produced, thus increasing the noise. Because of the wide range of working frequency and the wide range of rotating speed, it is difficult to avoid the natural vibration frequency of each component of the motor. But the inverter motor can solve these problems effectively. Variable frequency motor can deal with the problems of frequent starting and braking, such as efficiency, temperature rise, insulation strength, noise, vibration and cooling of ordinary asynchronous motor, fatigue and accelerated aging of mechanical structure and insulation structure caused by frequent starting and braking, and can effectively reduce the instantaneous voltage of motor during starting.
YVF2 inverter motor is more energy-saving
In the operation of the motor, all the household appliances produce different levels of harmonic voltage and current, which make the motor run under non sinusoidal voltage and current. The higher harmonic will cause the increase of stator copper consumption, rotor copper consumption, iron consumption and additional loss of the motor, the most significant one is the team copper consumption. Because the common AC asynchronous motor rotates at the synchronous speed close to the fundamental frequency, the high-order harmonic voltage will produce a large rotor loss after cutting the rotor bar with a large slip. In addition, additional copper consumption due to skin effect should be considered. These losses will be suitable for the extra heating of the motor, reducing the efficiency and output power, but if the variable frequency motor is used, its energy consumption can be reduced by about 20% - 30%.
YVF2 variable frequency motor can change speed without pole
Stepless speed regulation is from stop to the fastest speed, or from the fastest speed to stop, without gear, it is gradually faster or slower. In addition, all DC variable-frequency motor can divide the motor speed into many gears through frequency converter to control the motor speed and actual demand, while the maximum number of gears of AC brush motor is only 3, which can not achieve the effect of frequency conversion.
YVF2 variable frequency motor has longer service life
When the motor is running, the carrier frequency is about a few thousand to a dozen kilohertz, which makes the stator winding of the motor bear a very high voltage rise rate, which is equivalent to the steep impulse voltage applied by the motor, which makes the motor turn to turn insulation bear a more severe test, while the variable-frequency motor can work under the voltage of the rectifier filter, the performance can be more stable, and the service life is longer 。
Yongkun motor factory supplies micro speed regulating motor, gear reducer, YVF2 variable frequency motor, three-phase asynchronous motor, DC-AC shaft reducer and other types of reducer. Different types of motors have different functions and characteristics. Therefore, it is recommended that the user of the equipment choose the motor suitable for its working condition.
