Taiwan's three Acer Electric Group is an industrial automation \ intelligent motor control industry leader, the group administered Quanzhou Santrian Electrical Equipment Co., Ltd., Quanzhou Morikawa Electric Co., Ltd., Quanzhou 3-Electric Co., Ltd. and Shanghai Electric Technology Co., Ltd., Acer number of business entities, is a collection of Trade and Industry as one of the industrial electrical products, intelligent motor control product development and manufacturing company, is China's leading industrial technology and mechanical automation intelligent management experts; automated production base of 30,000 square meters and production capacity ranks domestic forefront, the company is also the first to introduce Taiwan's mainland capital tie inverter technology of international advanced production enterprises to set up factories in the country. Santrian Electric is the only authorized listing of Fujian Province, "engineering and technology research center" and provincial key "high-tech enterprises," the company annual sales of domestic low-voltage inverter ranking, with SANCH (three Acer), SANCHUAN (Three River) two well-known brand, SANCH- three Acer brand in 2005 namely "China's top ten drive brand" the title, is a model of both Taiwan and the mainland enterprises in the industrial automation field of capital, technology successful cooperation. What is the frequency motor drive means by a "special variable frequency induction motor + inverter" communication speed mode consisting of a high degree of automation machinery and electrical equipment, the current combination has completely replaced the traditional mechanical speed and DC Speed ??scheme; With the power electronics technology, the spectacular development of microelectronics technology, the use of "special frequency induction motor + inverter" AC variable speed mode, is its excellent performance and economy, led the field in the governor a governor to replace the traditional way of upgrading the changes. Due to the incomparable superiority and frequency motor speed control, thus making machinery automation and production efficiency greatly improved; EPS power supply as the trend of the future development of inverter technology which has its own peculiarities, but because of the high-speed variable frequency motor system or low speed, dynamic response speed and other needs, as the driving force for the main body of the motor, three Acer inverter proposed stringent requirements will lead to innovation in all aspects of electromagnetism, structure, insulation, etc. to the inverter motor. It can be said that because of relatively normal motor frequency motor superiority in terms of frequency control, who uses the drive where we are not difficult to see the figure of inverter motor. 50Hz frequency converter applications than you know, for a particular motor, the rated voltage and rated current is the same as the inverter and motor ratings are:. 15kW / 380V / 30A, the motor can operate at 50Hz When the speed is above 50Hz, the output voltage of the inverter is 380V, the current is 30A. At this time, if the output frequency is increased to 60Hz, the inverter maximum output voltage and current can only to 380V / 30A. Obviously constant output power So we call this time of constant power speed torque situation how it because P = wT.?. (w: angular velocity, T: torque) because P invariant, three Acer inverter, w is increased, torque will be reduced accordingly we can find another point of view: the motor stator voltage U = E + I * R (I is the current, R is the resistance of the electron, E is EMF) can be seen, U, I unchanged, and Taiwan, Acer drive, E also constant and E = k * f * X, (k: constant, f: frequency, X: flux), so when the 50 f -> when 60Hz,. X will be a corresponding decrease for the motor is, T = K * I * X, (K: constant, I: current, X: flux), so the torque T will follow the flux X decrease simultaneously reduced. less than 50Hz, three Acer inverter, since I * R is small, so the U / f = when E / f constant flux (X) is a constant. torque T and proportional to the current. This is why usually flow capacity of the inverter to describe their overload (torque) capability and called constant torque speed (rated current is constant -> maximum torque constant) Conclusion: When the inverter output frequency increases from 50Hz above output torque of the motor is reduced. three Acer inverter, Gai Like, three Acer inverter provided by the Dongguan City 盖利克 Automation Technology Limited.
