- Q:What is the characteristic of the variable pole speed method?
- Edit this paragraph speed method First, variable pole alignment speed method This kind of speed control method is to change the stator winding winding way to change the cage motor stator pole pairs to achieve speed control purposes, features are as follows: with hard mechanical properties, good stability; no slip loss, high efficiency; wiring Simple, easy to control, low price; stepless speed regulation, large level difference, can not get smooth speed control; can be used with voltage regulator, electromagnetic slip clutch with the use of high efficiency and smooth speed control characteristics. This method is suitable for production machinery that does not need stepless speed regulation, such as metal cutting machine tools, lifts, lifting equipment, fans, pumps and so on. Second, the frequency control method Frequency conversion is to change the frequency of the motor stator power supply, thereby changing the speed of its synchronous speed control method. Frequency converter system can be divided into AC - DC - AC inverter and AC - AC inverter two categories, most of the current domestic use - cross - frequency converter. Features: high efficiency, no additional loss during the speed control process; wide range of applications, can be used for cage type asynchronous motor; speed range, hard and high precision; technical complexity, high cost, maintenance and repair difficult. This method is suitable for applications requiring high precision and better speed performance. Frequency conversion speed is divided into the following basic frequency and frequency above the speed, the fundamental frequency is constant torque speed control mode, the frequency above the speed is constant power speed mode.
- Q:Laptop power adapter leakage
- You feel, or do not feel is to take the amount of pen? If the feeling after it, then for a, if the amount of pen, then hand touched, it should not be bright. That is a induction, is Virtual electricity, it does not matter.
- Q:What is the motor series parameter setting of the inverter? If it is with the spindle,
- Ordinary inverter standard drive is a 4-pole motor, the greater the number of poles of the motor, the greater the rated current, the motor pole number is the frequency converter when the self-learning automatically set, in the vector control must be self-learning
- Q:Laptop power adapter (no power supply, but indicator light)
- There may be reasons for the power adapter, there may be a computer can not identify the power supply is battery-powered or AC power. These are just speculated by your phenomenon, if you are better in the warranty period to the customer service test, so the best
- 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:Delta VFD-F frequency converter how to adjust the number of poles
- Look at the 07 motor parameters, I VFD-F instructions need, then the mailbox sent
- 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:Why G120 inverter to be equipped with 4-pole motor?
- Not necessarily must be equipped with four-pole motor, 2 pole, 6 pole, 8 pole, 12 pole can be used. As long as there is no problem with attention to current matching. Because the amount of 4-pole motor is the largest, all the frequency converter, are based on 4-pole motor for the control model design.
- Q:How do I protect the inverter when the three-phase two-pole motor is running?
- Three-phase two-pole motor running inverter protection, should be based on the protection of tips, check the corresponding manual to deal with. When the inverter protection has a corresponding protection tips (such as over-current, over-voltage, speeding, stall ... ... etc.), the product manual will generally give the corresponding protection tips. According to these measures to check, deal with, you can solve the problem.
- Q:Master Hello a machine requires 500 speed matching 6-pole motor frequency converter transferred to about 28HZ
- The belt rotation is calculated by the speed ratio. The current transferred to the motor by the inverter is approximately equal to the rated current of the motor, ie the motor's power is maximized.
