1. 控制电压:因为是控制电压(Voltage)与频率(Frequency)之比,称为U/f控制. 恒定U/f控制存在的主要问题是低速性能较差,转速极低时,电磁转矩无法克服较大的静摩擦力,不能恰当的调整电动机的转矩补偿和适应负载转矩的变化;其次是无法准确的控制电动机的实际转速.
2. 伏特:以前一代产品作为基础,Qspeed新款600伏特(Voltage)功率因数修正(PFC,PowerctorCorrector)整流器,不仅拥有更低的逆向复原电荷(QRR),且其转换效率为现今市面上所有矽二极体之最.
3. voltage的近义词
3. 电压值:火牛的 (WATTS) 是指可以提供的功率极限,而胆所示的 (WATTS) 是最大输出功率以上只是用一个好简单的比喻:提供电力的是不怕高 WATTS ,因开启电器时所 CONSUMPTED 的能量是高 WATTS 的,但电压可以不变. 不要因此而误解了,电压值 (VOLTAGE) 、电流值 (AMPERE) 和 功率值 (WATTAGE),请各位注意.
4. voltage的近义词
4. voltage:vol; 声过滤
1. 电压;伏特数
The voltage of an electrical current is its force measured in volts.
e.g. The systems are getting smaller and using lower voltages.
这些系统变得更小,使用的电压也更低。
e.g. ...high-voltage power lines.
