EMC Standard Introduction

According to the requirements of national standard GB/T12668.3, the drive need to comply with electromagnetic interference and anti-electromagnetic interference two requirements. The existing products of the company execute the latest international standards: IEC/EN61800-3：2004（Adjustable speed electric SVFl power drive systems-part 3:EMC Requirements and specific test methods) which is equivalent to the national standard GB/T12668.3.

IEC/EN61800-3 inspects the drive from EMI and anti-EMI two aspects, EMI mainly tests the drive's radiation, conducted and harmonic interferences ( Corresponding the civil drive has the requirement ). Anti-EMI mainly tests the drive's conducted immunity, radiation immunity, surge immunity, fast mutant burst immunity,ESD immunity and power low frequency end immunity (Specific test items are: 1. the experiment of input voltage dips, interruptions and changes immunity; 2, the experiment of commutation notches immunity ; 3, the experiment of harmonic input immunity ; 4, the experiment of input frequency change; 5, the experiment of input voltage unbalance; 6, the experiment of input voltage fluctuation).

According the stringent requirements of the IEC/EN61800-3 to test and according instructions shown in the 9.3 to install, Our products will have a good EMC for the general industrial environment.

Q: What is the number of parameters of the motor frequency of the Siemens inverter?: Siemens inverter motor pole number parameter code is r0313 motor pole pairs. Note that the number of pole pairs.

Q: What is the application of variable frequency speed control?: Generally used in the need for continuous speed control of the place. With the general exchange of motor than its advantages is able to continuously speed. DC motor, although also continuous speed control, but the price is expensive, the volume weight is too large.

Q: Does the teacher know the working principle of the inverter?: Very basic questions, the principle of fine you go online search, everywhere, I do not like to copy someone else, I simply tell you about: Voltage type inverter Three-phase alternating current to the rectifier module, converted into DC, filter stored in the electrolytic capacitor, IGBT + and - from the electrolytic capacitor to take energy, by the DSP (or other controller) output PWM pulse control IGBT turn on and off, So the output AC, the AC and input AC waveform is very different, so that the inverter is also a source of interference. Current filter in the middle of the filter is the inductor non-capacitance, we are more commonly used on the market and the economic converter are mostly voltage-type inverter.

Q: 6-pole motor, speed 8000 rpm, corresponding to the frequency converter output frequency is how much?: To 400HZ, so high frequency you tried it? I only tried 80HZ, if you tried, please tell me some of the high frequency of the actual situation will produce some changes in the motor,

Q: Laptop power adapter problem: First, that is called the transformer, not called the charger, not with you bite the word, but you according to the charger to Taobao search, basically one hundred percent are not found.

Q: Laptop power adapter output voltage is not the same as the current? What's the effect?: I would like to elaborate on the basic principle of the large standard current power supply can replace the small standard current power supply. Some friends have misunderstood, that a large nominal current power will burn books, because the current big thing. In fact, how much current in the same voltage depends on the load, that is, the work of the books, when the books of high-load operation, the current larger, the books into the standby time, the current is smaller, in short, On the voltage divided by the equivalent resistance of the books. Large nominal current power supply has enough current margin, will not be replaced by a small standard current power supply after the overheating or output voltage is too low. On the contrary, with a small current power supply instead of high current power on the existence of the above risks. But some friends with 56w power supply instead of 72w with no problem, because the power adapter is usually designed to leave a certain margin, the load power should be less than the power supply,

Q: What are the AC motor speed control methods? What are the characteristics of each: Pressure control speed, limited speed range is limited use of variable pole speed, change the motor internal wiring speed, speed is a very speed according to the motor factory set to brand speed to speed control, change the motor input Frequency to speed, are stepless speed is now more popular

Q: Who knows how the inverter is calculated?: There is no pole in the inverter, the electrode can be polarized, the greater the number of poles of the motor the slower the speed, please refer to.

Q: Motor a speed, the inverter will burn what is going on, the inverter is a large yuan: If you buy the inverter and the motor can match, it is certainly the quality of the inverter.

Q: 380V 2 pole motor can use the inverter?: Of course, the stator winding can be connected with concentric While enameled wire to be better, preferably 180 degrees or 155, and even dedicated enameled wire
