电机的输出功率 meaning in English
power output supplied by machine
Examples
- So far , most pump machines in ships are not taken action . when the level is high , pumps still work in high distance , which have the energy wasted
目前，国内绝大多数的泵船上的水泵机组未采取措施，电机的输出功率是恒定的。 - When the river ' s level is high , the purpose of saving energy can be realized by reducing the pump rotate speed and the output power of electric machines
在汉江处于丰水期高水位时，将水泵的富余出水扬程通过降低水泵转速节省下来，使电机的输出功率下降，达到节能的目的。 - The situation is not only changed with the water level but also the distance of pump machines . in order to ensure the working point being in high efficiency working area , the only way is to adjust correlative performance parameters
只有调整相关的性能参数，即水泵的出水扬程，才能保证水泵的工况点处在高效工作区，电机的输出功率与负载处于合理的匹配范围内。 - According to pump performance curve shown we can get that the distance h is changed with the rotate speed n in the same point q , and the flux q is changed with the rotate speed n in the same point h . from the curve we can get the rule that the distance and rotate speed are in direct with ratio at the same flux point , and the rotate speed and the flux are also in direct with ratio at the same distance point
根据相似定律：流量与转速的一次方成正比；扬程与转速的二次方成正比；功率与转速的三次方成正比。即在降低转速，调低水泵出水扬程的同时，功率下降的幅度非常大，从中可以节省相当大的电能。完全应在高水位时降低水泵机组转速，从而使电机的输出功率随着转速下降值与转速原值商的三次方关系下降。 - For an ev drive system , the variation of rotor time constant will bring on variation of torque and exorbitant line voltage even the field orientation may be destroyed . the varied torque will affect ev dynamic performance , and the higher voltage will limit the output power due to the bound of batteries in ev
对于电动汽车驱动系统来说，转子时间常数的波动会导致输出转矩和电机电压的波动，并且严重时会导致系统出现振荡，转矩的波动会影响汽车的动态性能，电机电压的波动则会由于电池电压的限制而影响电机的输出功率，这些都是电动汽车的驱动系统应该避免的问题。
