3Improved versions of the steam-driven elevator appeared in the next three decades, but no significant advance took place until the introduction of the electric motor for elevator operation in the mid-1880s and the first commercial installation of an electric passengerelevator in 1889. Encyclopedia Britannica

接下来的三十年里出现了各种改进了的蒸汽驱动升降梯，但是并没有什么意义重大的进展，直到十九世纪八十年代中期出现了用来运行升降梯的电动马达，以及 1889 年安装了第一架用于商业目的的电动载客升降梯。

However, the amount of electricity it produced was very tiny. There was still another use for induction. Faraday also created a tiny electric motor—too small to do the work of a steam engine but still quite promising.

Faraday 也制造出一种小型电机，它太小以至于不能取代蒸汽机器的工作，但仍然非常有前景。

The CORR series is about tuning, tire technology, and shock valving , commented cliff lrey , ford tuck motor sport steam lead .

CORR 系列是有关调音的事，使疲倦技术，而且震动给～装阀门，批评悬崖 lrey，浅滩缝褶马达运动蒸气带领。

Starting Torque and work great torque motor operating current large, generally 80 ~ 120mA range.

起动力矩及工作力矩大，电机工作电流大，一般在80～120mA范围。

Based on the above analysis, we believe that the simplest solution is to bus voltage 6kV within the allowable range (± 10%) increased number, in order to improve the motor starting torque, reduce the startup time.

根据上述分析，我们认为最简单的办法就是将母线电压6kV在允许范围内(±10%)提高一些，以提高电机的启动力矩，缩短启动时间。

50Hz - 60Hz to get high rotary torque at low starting current, and also the motor at a lower starting

相交流电动机上作起动用，使电动机在较低的起动电流下得到较高的转矩。

At last, the multi-slice model for the representation of skew is built, which can directly calculate the starting current and starting torque of energy-saving motor according to terminal voltage, the reliability of this method is verified by comparing the values between calculation and test.

最后论文建立了考虑转子斜槽结构的多截面有限元模型，以端电压为输入量，可直接计算出节能电机的起动电流和起动转矩，计算结果与实测数据的比较验证了该方法的可靠性。

A simulation research is conducted on the example of six-phase double star winding shifted by 30°synchronous motor.In order to investigate the control algorithm of multilevel inverter , high harmonics as well as its problems, a mathematical model of the control algorithm based on the voltage space vector is built. For the first time, the principle along boundary is introduced to confirm the chosen switch state when many switch states are corresponding to the same vector. Simulation analysis and hardware realization are conducted with the combination of diode clamped three-level inverter and five-level inverter.
