asynchronous induction motor造句

Similarly to JR East's Fastech 360 programme, the plan is to develop and test both asynchronous induction motors and permanent magnet synchronous motors in the train.
The motors are newly developed three-phase asynchronous induction motors, rather than synchronous motors as in the KTX-I . However, testing found limited improvements in efficiency and noise levels, and problems with reliability.
Elements common to all variants include the steel bodyshells, the two bogies with two powered axles each, the three-phase asynchronous induction motors, the cooling exhausts on the roof edges, and the wheel disc brakes.
The traction motors are asynchronous induction motors like those of the HSR-350x, rather than synchronous motors as on the KTX-I . rather than the originally foreseen Each traction converter consists of two parallel-switched four-quadrant converters, which function as rectifier modules by converting single-phase alternating current ( AC ) from one main transformer winding each to direct current ( DC ), a 2, 800 V DC intermediate circuit, and one inverter module converting the DC supply to the three-phase AC supply for traction motors.
It's difficult to find asynchronous induction motor in a sentence. 用asynchronous induction motor造句挺难的
