Foreword

This standard is equivalent to using IEC TS60034-17.2006 "converter-fed cage induction motors Application Guidelines" (in English). This standard replaces GB/T 20161-2006 "converter-fed cage induction motors application guide." This standard compared with GB/T 20161-2006, change the following exceptions. a) Introduction add paragraph. This technical specification applies to the motor within the GB/T 21210-2007 predetermined range, that is, according to the power grid design Low-voltage series three-phase cage induction motor rotor comprising N H design or design. Inverter power supply designed electric Machine should perform GB/T 21209-2007. b) Chapter 4, voltage, and frequency spectrum (or) current of the inverter is different has been described. c) Chapter 5, the loss caused by harmonics, GB/T 20161-2006 Chapter 5, titled additional losses, was replaced by damage caused by harmonics Consumption, discussed is powered by the drive cage induction motor voltage and current harmonics generated by the additional iron losses and rotor windings Losses, additional losses to distinguish when the power grid generated by the motor. GB/T 20161-2006 Fig. 3 (Fig. 4 of this standard) power supply to the drive cage induction motor (frame size 315M, N Design) at the rated torque and speed of the impact of the loss, the loss ratio in which the voltage of the inverter harmonic generation made repair Change, specific changes are as follows. F --- the stator winding losses from 0.5% revised to 2.5%; G --- rotor winding losses from 2% revised to 4.5%; H --- iron consumption from 12% revised to 7.5%; I --- the additional load loss is still 0.5%. d) Chapter 7, increasing the torque ripple is described by the intermediate circuit ripple current. e) Chapter 8, electromagnetic noise, were revised. f) Chapter 10, bearing currents, were revised. g) an increase in Chapter 11 Installation (cable wiring, grounding, link). The standard proposed by China Electrical Equipment Industrial Association. The standard rotary motor by the National Standardization Technical Committee (SAC/TC26) centralized. This standard is drafted by. Shanghai Electrical Apparatus Research Institute (Group) Co., Ltd., Hebei Electric Co., Ltd., Shandong Huali Electric Group Co., Ltd., Shanxi motor manufacturing Co., Ltd., Xiangtan Electric Co., Ltd., Beijing Bi Jie Electric Co., Ltd., Zhejiang GB 755-2008 rotating motor fixed and performance (IEC 60034-1.2004, IDT) GB/T 21209-2007 inverter power supply cage induction motor design and performance guidelines (IEC 60034-25.2004, IDT) GB/T 21210-2007 starting performance of single-speed three-phase cage induction motors (IEC 60034-12.2002, IDT) Characteristics of the motor 3 During the commutation, the output current of the current flowing through the inverter to the motor stator windings. Therefore, knowledge of the motor equivalent circuit Commutation circuit design is important. Voltage inverter, motor equivalent circuit knowledge of the commutation circuit design is usually not important, but the harmonic impedance of the motor For losses due to harmonics caused there is a significant impact. The above basic operation related to driving ability. Additional torque can occur if the drive power demand to know the runtime (in particular Specific details of the oscillation torque) and additional losses, we need to know the motor in the entire range of the harmonic spectrum of the equivalent circuit parameters. Since N design of cage induction motors have a variety of designs (for example, copper-row deep cast aluminum rotor cage rotor and a double), important harmonic The wide frequency range (bandwidth 0kHz ~ 30kHz), it is impossible to determine a universally valid motor equivalent circuit. usually Do not allow the use of frequency in steady-state operation of the equivalent circuit parameters (such as anti-leakage during normal operation) to calculate the rotation caused by harmonics Moments and loss. Only when the inverter output current and (or) when the voltage spectrum is known, the motor manufacturer can provide a suitable electric Machine equivalent circuit parameters. Spectrum 4 voltage and (or) current In order to obtain the amount of torque reduction and torque oscillations caused by harmonics, to understand the spectrum of motor voltage (voltage inverter) or electric Machine current spectrum (current inverter) is essential. Figure 1 shows a typical waveform of a current motor phase current inverter power supply. Harmonic generated by the shape = 5,7,11, 13. Effect of the corresponding harmonic content by commutation interval, different drive systems in the time interval is different. GB/T 20161-2008/IEC TS60034-17.2006 ......
