Q:Inverter 0.2KW, the motor speed requirements down to 4 turn, the motor pole 4 pole. Can the drive drive the motor?
Can, but this is a test product, the application does not try!
Q:How does the spindle drive system of the inverter realize the positive and negative control of the main pole?
Communication can reach a longer and more stable, generally better of the city 485
Q:What is the difference between the electronic governor and the frequency converter on the motor speed regulation?
Electronic governor is for single-phase motor, by changing the access winding resistance and capacitance to adjust the motor speed, the speed of the power supply power for the output does not change, so this speed is not an energy Type of speed control methods, such as home for the use of fans and the like. Inverter speed is the original direct input three-phase asynchronous motor power first access to the inverter, in the inverter through the PWM and other electronic converter technology to rectify the frequency AC, inverter, become a frequency controllable AC In the input to the motor, in the motor running through the V / F control, output torque control, vector control and other control methods to adjust the frequency, change the loop current, to achieve energy-saving operation, especially in the light load energy efficiency is obvious, An energy-saving products that have been widely promoted and applied
Q:A 4-pole AC motor into a 2-pole AC motor, the motor is controlled by the inverter, to make the maximum speed of the 2-pole motor and the original 4-pole
First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
Q:Will the 75KW4 pole motor can be used to increase the speed of the inverter?
China's power frequency 50hz, and the motor rated frequency match, blindly by increasing the frequency of the inverter output motor speed is not desirable, will affect the motor magnetic circuit, work is not normal.
Q:Three-phase two-pole motor can be used to reduce the frequency of the inverter
If you need to be very slow, you can match a four-level motor ah, even more slowly with a reducer
Q:Can the laptop's power adapter be used for years?
Most laptop power adapters can be used for 100 ~ 240V AC (50 / 60Hz). Basically, most of the notebook computers are external power supply, with a power cord and the host connection, which can reduce the size and weight of the host, only a very small number of models built in the host power.
Q:Variable frequency pump pressure in the very low flow instability, why?
. If you want to stabilize the pressure, you must adjust the pipeline characteristic curve is the work point to enhance, so that you can both stabilize the pressure and adjust the flow.
Q:ABB frequency converter and the difference between domestic frequency converter
Optical microscope mainly by the eyepiece, objective lens, stage and mirror composition.
Q:Three motors, if coupled with the governor speed, is it necessary to add the inverter?
First, the frequency control: the use of frequency converter to change the frequency of the motor stator power supply, thus changing its synchronous speed control method for all motors, which is the most advanced, the most widely used speed control method.
As the leader in the field of medium Voltage Variable Frequency Drive, we have been focusing on providing the integrated solutions of automatic control and energy-saving technology etc. for customers, and its skill levels and market impact of medium voltage VFD are in the world-leading positions. We have provided products and services across more than twenty countries in six continents around the world, taking up the first market share (China) in the past nine years.
