YVF2 series variable frequency speed regulating three-phase asynchronous motor is a special asynchronous motor suitable for running in the speed regulating system powered by the inverter. Suzhou Deneng Motor Co., Ltd. in the unified design on the basis of technical improvement, the use of special enameled wire, adjust the electrical scheme, reduce the harmonic content, so that the motor in addition to energy saving, stepless speed control range, low vibration, low noise, but also has the advantages of smooth operation, no torque crawling phenomenon, long service life. Widely used in light industry, textile, chemical, metallurgy, machine tool industry other need to adjust the speed of the equipment.

The motor inverter are used together to achieve constant torque speed regulation at 5-50HZ; 50-100Hz to achieve constant power speed regulation.

It can be equipped with an independent fan, so that the cooling effect of the motor is reliable constant in the whole frequency range.

Main Performance Main Performance

• Rated Power Range:0.37-315KW

• Rated Frequency: 50Hz

• Rated Voltage: 380V

• Motor Poles: 2, 4, 6

• International Protection Standard: IP54

Insulation system:

Designed according to grade F (155P), the temperature rise of the motor is assessed according to 80K when rated output direct power supply.

The temperature rise of the second fourth poles of the 315 frame the motor of the 355 frame is allowed to reach 105K;

Motor cooling mode: The standard cooling mode is IC416 forced air cooling, but it is equipped with fan load

When the low frequency does exceed 30Hz, the IC411 self-fan-cooling type can be selected;

Motor 315-355, 200 above 2-pole motor standard with oil injection nozzle, 132 above motor optional;

Casting material: cast iron; Standard installation structure types: IMB3, IMB5, IMB35, etc.

The motor can choose PTC PT100 thermistor for winding protection, the winding temperature measuring device can also be installed, [bearing temperature measuring device can be selected for motors above 60;

Special design: Our company can design special voltage, frequency motor according to customer requirements; The appearance color of the motor can be adjusted according to customer requirements.

When the motor is adjusting speed to high frequency, it should pay attention to:

If it is a fan, pump load, it should be noted that the power of the load will increase when the frequency is higher, such as exceeding the rated power of the motor will cause motor damage; When the motor running speed exceeds the rated speed, the noise vibration value will increase, the bearing life will be shortened; The maximum safe speed of the motor operation is as follows: The maximum safe speed of the motor operation frame number Maximum speed maximum frequency.

the maximum safe speed of the motor. The maximum safe speed of the motor
