在交流电路中,有效功率与电流和电压的相位角有关。 3.2. 虚功率 (Reactive Power) 虚功率是指在交流电路中,由于电感和电容的存在,电流和电压之间产生的相位差所导致的功率。虚功率用符号 ( Q ) 表示,单位是乏(VAR)。 3.3. 视在功率 (Apparent Power) 视在功率是指电路中总的功率,包括有效功率和虚功率。视在
How to Calculate Power Factor To calculate power factor, you need a power quality analyzer or power analyzer that measures both working power (kW) and apparent power (kVA). With this data, you can calculate the ratio of kW/kVA. Power Factor Formula The power factor formula can be expressed...
All you need to know to calculate a motor´s max./actual torque is its max./actual current. Torque and current are proportional, in the same way that rotational speed and voltage are proportional. rot.speed = voltage × Kv torque = current × Kt where Kt = 1/ KvKt is the ...
