一种新型直流电机

法接第单极电机具有电压低的特点，现有的直流电机在本质上属交流电机，只是经过换向器整流成为直流电，所以具有转速低，功率小，维护费用高的缺点。本文介绍的新型电机既没有整流子又与原始单极电机有着本质区别，使其既具有单极电机的优点，又克服了单极电机的电压低等缺陷。

A New Type of Direct -current Machine

Faraday's single-pole machine has the disadvantage of lower voltage. Now direct - current machine intrinsically belong to alternating - current machine,only it use commutator to change alternating-current into direct-current. So it has drawback of low rotational speed, low power, high maintenance cost etc. , In this paper we introduce a new direct - current machine without commutator but it has intrinsically difference in primeral single - pole machine and both single - pole machine advantage such as no commutator and no drawback of single -pole machine such as low voltage.
