No, you are charged by the wattage that you use. Watts are the product of amps times volts. Say you have a device that draws 5000 watts and you are using a voltage of 480 volts then the amperage will be A = W/E = 5000/480 = 10.4 amps. Now using that same wattage at 208 volts the amperage will be A = W/E = 5000/208 = 24 amps. As you can see the only thing that changes is the current (amps) on a consistent wattage with different voltages. One big advantage on using higher voltages over smaller voltages is, with the amps being lower, a smaller wire size can be used for the same wattage load. In the end though, you are still billed on the wattage used.

Is there any advantage of 208V vs 480V three phase?
208 v. equipment is a little smaller and cheaper, and 208v. is slightly safer to use. However, 480v. runs on half the amperage 208v. equipment does, which means equipment or devices cost almost 50% less to operate. With respect to energy consumption, the answer above is incorrect. It is true that equipment that operates at 480v does operate at roughly half the amperage vs. 208v, however, it operates at over twice the voltage. Your local power company charges you per kilowatt hour (voltage x amperage), not on amperage alone. Example, a 208v motor that draws 10 amps would consume (208v x 10a) 2.080 kilowatts per hour. The same motor on 480v would draw roughly half, 4.3 amps (480v x 4.3a) and would also consume 2.080 kilowatts per hour. So in terms of power consumption, they are virtually the same. The main reasons one would opt for higher is the fact that you can install smaller wire and you can run longer distances. It's a ratio that is directly proportional (at least with electric motors/inductive loads). If you were comparing a 240v motor to a 480v motor the ratio would be exact, if a 480v motor draws 5 amps, the same motor on 240v would draw 10 amps.
How do you calculate the cost of running a 7.5 HP 230V ac Motor which runs 24 x 7?
total hour = 24*7 = 168 hrs now 1 h.p. =0.750 kw 7.5h.p. =(?) Hence = 5.625 kw hence total unit = kw*hrs =5.625*168 =945kwh NOw cost = unit/hrs *motor running hrs =6 Rs for indust * 945 =5670 Rs
What is the approximate efficiency of a 60 cycle 6 pole induction motor running at 1050 rpm and having a synchronous speed of 1200 rpm?
A round figure might be 85-90%. But smaller motors are designed for lower efficiency to reduce the cost of the motor, and high-powered motors are designed to be highly efficient, despite the increased cost, to avoid wasting a significant amount of energy.
Application of induction motor in industry?
Induction motor used in industries for variable speed machines . Induction motor has always lagging power factor. Less cost compared to syn. Motor.
How much does heating cost?

Cost for new motor 1983 cavalier z24?
Typically, these came with a 2.0 liter 4 cylinder, or a 2.8liter V6 FWD style. Both of these motors are getting hard to find in running condition. Cost will depend on what motor you have and the area you live in.
What is wrong if your fiber optic tree motor that turns the light wheel stopped working and a little oil did not help and the light works but the color wheel does not turn?
Do you hear the motor running? If there is no sound, the motor has probably burnt out and needs to be replaced. If you do hear the motor running, you've probably stripped a gear. They can sometimes be replaced, but it might be more cost effective to replace it.

How do you calculate the cost of electricity bill of a 3 phase 125kW induction motor running at 400v 50Hz motor running for 8 hrs condition if 1000w equal to Rs0.238?
To answer this question, i need the power factor of the motor.CommentYou don't need the power factor, as you already know its true power (watts), but you do need to know the efficiency of the motor to determine its input power. You also need to know the cost per kilowatt hour.But you can get a rough idea by multiplying the number of kilowatts, by the time in hours, by the cost per kilowatt hour. For a more accurate answer, you need to divide this by the efficiency of the motor.
What is Running cost?
Running costs in are associated with companies and businesses. The running costs are simply the amount of money needed to make the company "run". Running costs include staff payment, electricity costs and resources etc. Running costs are the cost for day-to-day running of the business

What mean of starting device adds to the cost of the motor?
If a motor cannot be blindly switched on, in other words a control system for switching the motor on is required, then it will cost more than just the motor by itself.
