Servo control system can give the inverter signal,
- but want two motor synchronization, it should be impossible, the converter does not reflect so fast, and the speed is not so stable.s
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.s
What is the difference between variable frequency motor and variable speed motor?
- Give you a formula, you can understand their speed control principle: N (speed) = 60f (frequency) divided by P (magnetic pole logarithm) According to the formula, when you want to change the motor speed, there are only two ways to change The number of pole pairs and the frequency of the power supply. Speed motor is variable pole speed, that is, in this motor has 2 to 3 sets of windings, by changing the winding connection, to change the motor pole to change the rotation speed.s
The laptop's power adapter is too hot to do
- Installed adapter heat should be no problem, I am now under the books, the fan mouth is very hot, the weather may be more and more hot its
Huichuan frequency converter drag a 4-kilowatt four-pole motor to change the six pole can?
- Change 6 will only be slower, the fan is no longer role.
The frequency converter has a power parameter, as long as the motor is less than or equal to this power can be.s
Taian inverter 3.7KW 380V with 4.0KW 2 pole motor 18000 to 300HZ can it?
- With green wave Jie can experience to judge, there may be two possibilities: First, the inverter power selected small. Bipolar motor, not a four-pole motor, the inverter is designed according to the four-pole motor model, so in the inverter selection, can not only look at the power, but also the rated current of the motor;s
What is the frequency converter used to do, why some motor with the inverter?
- Frequency converter is widely used in the speed regulation of AC motor.Varameter speed control technology is an important development direction of modern power transmission technology, with the development of power electronics technology, AC 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.s
B2b frequency how to speed
- AC motor speed control methods are four: frequency, transformer, variable pole and winding motor to change the rotor loop resistance of the speed control method. Its source is based on the motor speed formula: n = (1-s) * 60f / p where: n --- motor speed s --- motor slip f --- power frequency p --- motor pole Logarithms
