FAQ

Can the laptop power adapter be generic?
Output voltage, current, interface can be used as well.
Will the asynchronous motor pole change the number of speed control can also be combined with the frequency converter
but the use of the inverter is based on changes in the load by changing the frequency of power into the motor at any time speed control, you can achieve a smooth and accurate stepless speed control is Now widely used in a speed control method, especially for the load often change or often in the light load operation of the motor.
What are the differences and links between the soft starters and the frequency converters, and their respective principles and uses?
The soft starter is activated by adjusting the voltage and current, and the frequency converter starts the motor by changing the frequency of the power supply. The soft starter can theoretically smooth and gradually start the motor to the maximum speed. No impact current (ordinary start-up current is 6-7 times the rated current) The inverter is best suited for tap water and fans, etc. The soft starter is not suitable for everything except for heavy load start.
90KW inverter start 90KW, 4-pole motor and 6-pole motor j What is the difference? The inverter can be used for it?
Two motors can use the same frequency converter, but the motor nameplate data through the parameters to adjust the input when the inverter should pay attention to some
How to make the motor speed (control speed), can not use frequency
Do not use the variable frequency motor with the speed motor
Is the laptop power adapter high temperature normal? Is there anything else?
Hello, the power adapter because there are a lot of electronic components so hot is normal, the general hand feels hot does not feel hot on it, if hot, then there is a problem.
Speed regulation method of three - phase asynchronous motor
Change the number of pole pairs can be adjusted, in the way around the stator coil through the tap method can achieve two-speed. With the popularity of the inverter, three-phase asynchronous motor speed mostly with the inverter.
What is the IGBT? Our inverter IGBT fried,
Basically change the voltage, the voltage changes in accordance with the different frequencies, so that change the speed.
