谐波起动电动机设计

本设计提出一种用于绕线型感应电动机的新型转子绕组,这种绕组在设计构思中引入"无感"的概念,其自身折算电阻在电机起动时可呈纯电阻性增大,不再需要另外串入电阻,并在运行时恢复正常,因而能使电机既有好的起动性能,又有高的运行性能,同时也简化了转子结构。

The paper proposes a new type of rotor windings which are used in wound-rotor induction motors. The windings draw into the concept ＂inductionless＂ in their design. Thus the rotor resistance of the motors start and return to normal while the motors run. The motors have good starting characteristics and running performance, and high reliability because their rotor constructure is simpler than conventional wound-rotor and it is unnecessary to add any additional resistors in the rotors in the rotor circuit.
