![]() Loadhook can insure the electric chain hoist you’re seeking for your operations ensures maximum safety, efficiency, durability and economy. The calculators below can be used to calculate electric motor amps, horsepower and 3-phase kVa. If you are mounting the hoist to a motorized trolley, you will need to add the two horsepower values together (hoist and trolley) and then use the chart to determine the total amp draw.Īdditional items will need to be taken into consideration as your system gets more complex. Calculate amps, hp and kVA for electrical motors. The spec sheet for the hoist will tell you the horsepower value for that hoist. An electric chain hoist uses a motor for the lifting operation. A rule of thumb states that you should multiply the power in hp by 746 to get the power in watts. You will need to know these two values to accurately determine the amp draw based on horsepower. The below chart breaks down the values based on single phase or three phase power which would be the power supply in your area as well as standard voltages. Knowing this value is important during the design or development stage of your purchasing process because it identifies if your circuit has enough ampacity to handle the additional load of the hoist. Calculates dc power / voltage / current / resistance. Here we are determining the amp draw of an electric chain hoist based on the horsepower of the motors. Watts (W) - volts (V) - amps (A) - ohms () calculator. Horsepower is a unit of power that is the rate at which work is done. kW to Amps Calculator is a conversion calculator that converts the power from kilowatts and voltage in volts to current amps, you will be required to enter. ![]() Amp draw measures how much power your machine consumes during operation. Example Work out the phase current, in amperes, given that the power factor in a circuit is 0.7, the power consumption is 0.44 kilowatts and the RMS voltage is 110V. ![]()
