We can quantify the motor’s part-load by comparing the measured input power under load to the power required when the motor operates at rated capacity using this formula.įirst step for actual value of voltage and ampere,i suggest to collected measurement data from motor using the Voltmeter and Clamp on meter.Example as following :.

We need to determine the full rated load in kW We determine value of power in kW (Pi) using this formula. We have 1 unit Induction Motor with 30 horsepower (hp),running with 34.9 amps for amperage load and 460 volts 3 phase and power factor value is 0.75 and motor efficiency is 85%

It is combination from Amperage and Voltage value.Basic formula for Power is P (watt) =I(ampere) x V (volt).Power also measured in Horsepower (hp) unit.For common conversion from electrical Horsepower to Watt is 1hp = 746 watt.Įlectrical motor loads are calculated from power in kW and full rated load in kW.Following is the formula how to calculate Motor loads. What is meaning of Power?Of course this term is significant with our discussion topic.Power is rated of energy in electrical circuit. On my last post,i discussed about why we need to determine motor loads and efficiency.So for this post i want to share how to get the motor load value using simple calculation electrical formula.īefore we go further,i want to explain about Power.
