摘要
工频电源情况下,2极电机高于同步转速3 000r/min运行时必须使用变频器调速,对于单相微型电动机来说存在装置体积大、费用高和工程经济性差等问题,通过一种简便可行的成倍调高电机转速的途径,达到成倍调高电机转速的目的。设计和构建了倍频驱动器以调控电机输入电压,使得单相微型电动机在2倍于原来转速下平稳运行。样机实验表明,倍频驱动器能够有效调控电压频率和幅值以满足电机在成倍调高转速时的驱动需要,实现了成倍调高电机转速的目的。构建的倍频驱动器由常用电力电子器件构成,结构简单,成本低廉,益于电机调速实现降耗节能。
The 2 polemotor working in over 3000r/minsuper-synchronous speed must use the frequency converter with 50 Hz frequency power. For single-phase micromotor, there are some problems with the use of the frequency converter, like the large volume, high fees and poor engineering economy, through a simple and reliable method to make sure it could achieve the purpose of multiply increasing the motor speed. A frequency multiplication driver is designed and constructed to control the voltage which is inputed to the motor to make sure the single-phase micromotor could work in twice of original speed. The prototype test results show that the frequency multiplication driver could effectively control the frequency power to meet the need of the motor driver, it makes the single-phase micromotor speed to twice of original speed. The frequency multiplication driver is designed by common power electronic components, it has simple structure and costs low, it has advantage in energy-saving in motor speed contorl.
