永磁式直流测速发电机的特点

随着新型永磁材料的不断产生和应用,永磁式直流电动机也越来越被广泛地应用于各行各业。永磁式直流测速发电机在低速控制系统中被作为反馈元件或稳速元件。它除具有一般测速发电机的优点以外,还具有结构简单、紧凑,反馈灵敏度高,低速精确度高,输出斜率大,线性误差小,可靠性好,寿命长等特点。介绍了永磁直流测速发电机的设计及其主要特点。

Characteristics of permanent magnet DC tackogenator

Permanent magnet DC motor has been applied more and more in every trade along with the new PM material has been produced and applied. Permanent magnet DC tachogenator is used as the component of feed- back or damping. In addition to the advantages of common tachogenator, it has a series of characteristics such as simple and tightly packed construction, high sensitivity of feedback and accuracy in low speed, large output slope and minimal linear error, well dependabihty and a long life etc. This text is mainly about the design of permanent magnet DC and its main characteristics.
