System Principle of High Voltage 6KV Frequency Inverter

High Voltage 6KV Frequency Inverter

Q:The emitter E of the inverter inverter module and the AC output U are not directly connected together: Pairs of modules are connected in a phase branch The phase output is derived from the neutral point between the modules

Q:3.7KW inverter with 2.2KW 6-pole motor running to see the inverter shows the current is more than 4A, with the amount of clamp to 2.8A: Inverter output has high harmonics, the current can not use digital clamp meter amount, and use electric clamp meter. The current of the inverter will vary with the voltage, but not the linear relationship.

Q:How does the spindle drive system of the inverter realize the positive and negative control of the main pole?: The general inverter has an external terminal control and communication control two modes optional, select one of them can be completed ah

Q:What is the frequency converter used to do, why some motor with the inverter?: 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. The motor is equipped with the frequency converter.

Q:Octopus AC Servo motor can be driven with ordinary inverter?: If it is synchronous motor, it depends on whether you choose the inverter is compatible with the synchronization machine, most of the incompatible. As you said the situation, the motor 8 pole, may be synchronous motor. Specifically, you can compare the rated speed and rated frequency to see if there is a slip rate to determine whether it is synchronous or asynchronous motor.

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.

Q: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.

Q:If it is 8-pole variable frequency motor, enter the motor nameplate parameters in the inverter input for the 4 pole can?: Motor brand above all, the general number of wrong is the inverter shows the speed is not right, for the speed control requirements are not high places will not be a problem, you can use

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:What is the frequency of `30 points: frequency conversion By changing the AC frequency of the way to achieve AC power control technology is called frequency conversion technology
