We are inThree-phase asynchronous motorThe nameplate will see "rated power", so what does this rated power refer to? followMori machineXiaobian to learn next!

       In factThree-phase asynchronous motorThe "rated power" on the nameplate generally refers to the rated shaft output power, which belongs to the active power; It is expressed by formula as rated current=Rated power÷1.732÷Rated voltage÷Power factor÷Efficiency; Here we takeMori machineYSSeries three-phase asynchronous motorYS90L-4For example: Rated power:1.5KW, rated voltage:380V, efficiency:79%, power factor:0.79; We use this to get the rated current=1500÷1.732÷380÷0.79÷0.79=3.65A, this time100%Input power at load=1.5÷0.79÷0.79=2.4kw.

       Of course, for safety reasons, it is recommended that the motor work at the rated state of the load80%Around. thereforeThree-phase asynchronous motorThe actual power consumption can be measured by a clamp ammeter at the input end of the three-phase current average, power consumption (unit:Degree)=1.732×Mean value of three-phase current:A)×voltage(voltage:V)×time(Unit:h)÷1000.

       Extension: If measured isSingle-phase asynchronous motorPower consumption=Single-phase current×voltage×time÷1000
