By adopting step pulsed current wave form and its programmed welding parameters(magnitude of main pulsed current and wire feeding...

This work contributes to the study of the all position welding technology for small thick-walled tubes φ32~42×3~5mm and its equipment. By comparing the effect of four kinds of pulsed current wave forms (zig-zag, trapezoid, trapezoid with sharp front impulse and step form) on the formation of weld, we propose that step wave form has the best advantage for all position tube welding. By adopting step pulsed current wave form and its programmed welding parameters(magnitude of main pulsed current and wire feeding speed), it is possible to weld small thick-walled tudes in all position efficiently with a sound quality without any edge preparation, and it is also possible to have complete fusion in the first pass followed by a second covering pass with filler metal. The special features of successfully developed all position programmed pulsed TIG tube welding machine are briefly described: no "pig tail" welding head with "three steel balls" wire feeding mechanism, step wave form pulsed welding current source with low distortion and its overall control system. The technology and equipment developed by this research work has been applied already in industrial production and satisfactory results have been achieved.

This paper discusses the pulsating toques of invetr er-fed induction motor which produced by the interaction of harmonic rotating fluxes with harmonic rotor current of a different order.The principal pulsating torques arise from the interaction between the fundamental rotating flux and the harmonic rotor currents. Their presence causes the change of the angular velocity of the rotor during a revolution. At very low speed, a series of jerks or steps takes place in the motor rotation, Therefore, the presence of pulsating torques may set a lower limit to the useful range of the motor speed. The pulsating torque can be reduced by improving current wave form of the inverter, such as a pulse-width modulated wave, increase of the number of stator phases and increase of the slip frequency, which can effectively reduce the amplitude of the torque pulsatin

本文论述了逆变器供电的异步电动机的脉动转矩是由谐波旋转磁通和不同次数的转子谐发电流相互作闸而产生的。主要脉动转矩是由基波旋转磁通和谐波电流相互作用产生的。脉动转矩的出现造成转子转一圈电动机角速度的变化。在速度很低时,电动机的转动会发生一系列的跳动或步进,所以脉动转矩的存在使电动机的转速使用范围有了一个下限。脉动转矩可采用改善逆变器输出电流波形的方法来抑制。如脉宽调制法,增加定子相数,转差频率增加法等都可有效的抑制脉动转矩。
