- 4 amps 960 va 480 volts 2 amps To find primary watts, we’ll call them volt-amps to differentiate them from secondary watts, we multiply primary volts times amps (480 x 2 = 960 va). To find secondary watts, we multiply secondary volts times amps (240 x 4 = 960 watts). Ideally, transformers do not alter power or wattage, again they only

Sorry if this sounds too basic but what determines the amperage draw of a small DC motor? I am trying to do a small project with my son that involves a 12V dc motor, waterproofed, that we attach a propeller and run underwater to create thrust. I first used a small boat bilge pump motor that is...# Dc motor amp draw calculator

A 25 amp charger will draw about 600 watts at 120 volts AC, so you can run it on a tiny 1000 watt generator, but you have to be careful and not run much else at the same time. You can run a 50 amp charger (about 1200 watts) on a 2000 watt generator, but again, little else at the same time.# Dc motor amp draw calculator

Consider a 600 hp large industrial motor driving a water pump. The motor is connected to a high voltage electrical supply of 680V. When this motor is energized, it must draw enough current to get the water moving and it is common for a motor to draw about six times its normal operating current for a short period of time. This can be troublesome.

The output mechanical power is of shunt dc motor is maximum when the back e.m.f. produced is equal to the half of its terminal voltage i.e. E b = V/2 Torque & Speed:# Dc motor amp draw calculator

E=IxR states that volts are equivilent to amps X watts So inversly volts divided by watts = amps in this case 120 volts divided by 100 watts =1.2 amps that given and adding that kwh=1000 watts used for 1 hr so inversly a 1.2 amp load used continuosly for 1 hr = 100watt hours or 0.10kwh I hope that helps# Dc motor amp draw calculator

Ohms Law Calculator Enter any two known values and press "Calculate" to solve for the others. For example, a 100 watt light bulb operating on 120 volts AC will have 144 ohms of resistance and will draw 0.833 Amps. Enter 100 in the Watts field and 120 in the Voltage field and press Calculate to find the resistance and current.# Dc motor amp draw calculator

Sep 25, 2017 · Depending on the motor, the armature resistance might be too low for any accurate VOM readings. Better to run an amp of DC current through it and read the voltage over the windings, with the armature locked. Find a nice power resistor and a variable power supply- adjust the voltage so it gives an amp through the series connected resistor and motor.# Dc motor amp draw calculator
