Product Introduction

High-voltage frequency converter based on H bridge series units. High voltage inputs directly. In order to save energy, phase-shifting transformer inputs the low voltage on the second side to each power unit of H bridge and the output series of each phase and all power units connect so it has formed high voltage to drive the motor that. It’s a high-tech, green energy-saving product integrating advanced automatic control technology, high-power electric and electronic technology, fast and reliable fiber communication technology, high voltage technology and digital signal processing technology.

Q: 380V motor addition to the inverter, but also how to change its speed?
Use the star connection to reduce the speed by changing the torque
Q: I have a 11KW-4 pole inverter, now with the 4KW-4 pole motor, what impact?
that is, the load is very heavy; caused by over-current burning inverter
Q: Servo control system can give the inverter signal,
If two motors are to be synchronized, only two servomotors are used, one is set to spindle and the other is set to slave.
Q: What is the principle and implementation of the inverter?
AC inverter principle. It is the first AC current will be converted into direct current, and then use the electronic components of the DC switch. AC power. General power of the larger inverter with a thyristor. And set an adjustable frequency device. The frequency in a certain range adjustable . Used to control the number of revolutions of the motor. The number of revolutions can be adjusted within a certain range. The frequency converter is widely used in the speed regulation of AC motor. Frequency control technology is an important development direction of modern power transmission technology, with power electronics Technology development, exchange frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply and other fields. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.
Q: Three-phase motor, quadrupole asynchronous motor to 15rpm, the inverter output how many volt voltage? The 4 V
The voltage does not change, but the frequency changes, about 0.5 Hz
Q: The motor is 2 pole with the inverter frequency to 50hz why the speed is only 1500 rpm
Motor speed formula: N = 60f / p In the above formula N - the speed of the motor (r / min); 60 - per minute (s); F - power frequency (hz); P - pole pairs of motor rotating magnetic fields.
Q: Lenovo g450 laptop power adapter specifications is what?
Input: 100-240V ~ 1.5A 50-60Hz Output: 19V - 4.74A
Q: What is the output voltage of the laptop power adapter?
Generally have 19V of the common friends, I was 19V
Q: 90KW inverter start 90KW, 4-pole motor and 6-pole motor j What is the difference? The inverter can be used for it?
Three-phase AC induction motor, 4-pole speed is generally 1480 rpm, 6-pole speed was 980 rpm
Q: Motor a speed, the inverter will burn what is going on, the inverter is a large yuan
If you buy the inverter and the motor can match, it is certainly the quality of the inverter.
