2 times the power consumption of the wind turbine and pump and the speed of the 3 power consumption is proportional to the speed of the rotating speed.
Through the speed control of the frequency converter to adjust the air flow, can reduce the power consumption DBU-22K-4
Give full play to the performance of the motor.
The excitation current is always adjusted to the best state, which can improve the efficiency of the motor.
Load torque is smaller, can further improve energy efficiency.
For example, when a general motor is used, the optimal excitation control mode in the 4% motor load torque is about 30% more than that of the V/F control. 1 axis servo amplifier.
MITSUBISHI general AC servo amplifier MELSERVO-J4 series.
Rated output: 1.0kw.
Interface: General purpose.
Power supply: three phase AC400V.
0.6kW and 1kW above the servo amplifier.
Servo amplifier supporting universal interface.
Servo amplifier for universal interface.
Speed / torque control of position control and analog voltage command can be carried out by using pulse train command.
Support Max instruction pulse frequency 4 Mpulses/s.
2 low frequency vibration can be suppressed at the same time by supporting the seismic algorithm of 3 inertial equipment.
Configurator2 MR to achieve convenient adjustment.
Effectively restrain the low frequency aftershock effect produced by the front end of the boom or the main body of the device 100Hz.
Can effectively shorten the time to control the stability of the aftershock.
In the XY design of trajectory control, improve the accuracy of arc track.
At the same time, it can effectively control the phenomenon of quadrant protrusion caused by the rotation direction of the servo motor, which is caused by friction and twisting. Type: HC-PQ type.
Output power: 0.4kw.
Rated speed: 3000r/min.
Electromagnetic brake: there.
Key axis: straight shaft.
Motor aspects: the material, structure and processing technology of the servo motor is much higher than that of AC motor,
That is when the driver output current, voltage, frequency change is fast power supply,
The servo motor can change according to the change of the response of the power supply,
Response characteristics and anti overload capacity is much higher than the AC motor drive,
Motor aspects of the serious differences between the two are fundamentally different performance.
That is not the inverter output can not change so fast power signal,
But the motor itself can not react,
So in the frequency of the internal algorithm set to protect the motor to do the corresponding overload.
Of course, even without the ability to set the output of the inverter is limited,
Some of the excellent performance of the inverter can be directly driven servo motor.
