Technical Advantages

- No need for long distance power supply filter and reactor
- Eliminate the influence of internal resistance of long-distance power supply cable on inverter control
- Eliminate the possibility of long-distance power supply cable grounding harmonic breakdown
- The motor is specially designed according to the frequency conversion performance and has a longer service life.
- No interference to other equipment, the system runs more stable
- No impact on the grid, low starting current
- Small size, no need for diverticulum placement or no equipment train
- Maintenance-free, improve production efficiency, reduce maintenance costs, and reduce maintenance time

Intelligent Permanent Magnet VFD Motor Controller Advantage

In addition to the excellent functions of the above-mentioned asynchronous all-in-one, there are the following advantages:
- Good power saving effect: power saving rate is increased by more than 30% compared with asynchronous machine
- Small starting current: Starting current is 15% smaller than asynchronous machine under the same starting torque
- Large starting torque: Under the same inverter capacity, the starting torque is increased by more than 15% compared with the asynchronous machine.
- High power factor: 25% higher power factor than asynchronous machine
- Low heat generation: Under the same load capacity, the temperature is lower than the asynchronous machine by more than 5 °C
- Small size: at the same power, the volume is reduced by more than 10% compared with the asynchronous machine

Application Advantages of Integral Drive Systems Ag

- The VFD and the motor are integrated, the motor is specially designed according to the frequency conversion performance, and the frequency conversion is designed according to the professional design of the motor, so that both can reach the best working performance.
- Space saving, no need for special diverticulum or equipment train to place the VFD.
- The VFD output contains a large amount of harmonic components. When the VFD is far away from the motor, it will generate a high induced voltage on the motor side, which may damage the insulation of the motor.

- The coal mining face, the VFD can not be very close to the scraper motor. An output filter must be used.
- After using the VFD, the motor and the VFD are very close, no output filter is needed.
- In the case of long-distance power supply, the internal resistance of the cable from the VFD to the motor cannot be ignored. When the VFD adopts sensorless control, it is necessary to accurately measure the relevant parameters of the motor, the internal resistance of the long cable, and the influence on the accuracy of the VFD control is very big.

- After the VFD is used, the distance between the motor and the VFD is very close, which eliminates the influence of the internal resistance of the cable on the VFD control.
-The output of the VFD contains a large amount of harmonic components. In the case of long-distance power supply, the overall distributed capacitance of the cable is very large. The high-order harmonics resonate during charging and discharging to the ground, which has a great impact on the insulation of the cable. .
- After using the VFD integrated machine, the distance between the motor and the VFD is very close, eliminating the cable resonance effect
