涡流制动器调速,是国外塔机较为流行的调速方案之一,国内也正在推广使用,但从目前国内使用的情况看,还存在电动机调速电阻选用不当,电动机调节特性与涡流制动器特性配合不合理的现象,不仅造成合成特性不够理想,而且还浪费电能,影响电动机寿命;涡流制动器元件本身的材质、结构、性能、体积与国外相比也还有一定差 Eddy current brake speed control, is one of the more popular tower crane speed control programs abroad, is also promoting the use of the country, but from the current domestic use of the situation, there are still motor speed resistance improper selection, motor characteristics and eddy current brake characteristics with Unreasonable phenomenon, not only caused the synthetic characteristics not ideal, but also waste electrical energy, affecting the life of the motor; eddy current brake element itself, the material, structure, performance, size and there are still some differences compared to foreign countries
