What is horse power of a 415 volt 3 phase 7.5 kW electric motor?
LexusLim
Motors are rated according to their output power, never their input power. This is because it is the output power that determines the load the motor will be able to handle. The output power, of course, is lower than the input power due to the machine's losses.
In North America, the output power is generally expressed in horsepower, whereas its input power is measured in watts. In the rest of the world, the horsepower is considered obsolete, so both the output power and the input power are measured in watts.
As there are 746 W to the horsepower, your 75 kW output motor would be equivalent to approximately 100 horsepower.

∙ 11y agoAn output power of 7.5 kW can be converted to horsepower by dividing by 746 W, as there are 746 W in one horsepower. So, in this particular example, the motor will have an output power of approx. 10 hp.

Minimum breaker size 60 horsepower motor?
Need motor voltage, amperage and phase to give you an anwer.
How do you use a one phase motor in place of a three phase motor?
To use a single/one phase motor instead of a three phase motor is possible if you have a three phase power supply as you will only need to tap one of the three phases together with neutral and an earthwire, however to use a three phase motor instead of a single phase will require the provision of three phase power supply.
Up to how much HP are single phase motors maufactured?
Horse power is horse power, regardless of what voltages and currents are used. 5 HP single phase is equal to 5 HP 3 phase.
Why you deserve phase 3?
You can get a 3-phase supply in most properties by negotiation with the power company, if your demand for electric power is high enough.
What is the simplest way to run a 3 phase 380 V motor of about 1 KW directly on 220 V single phase supply without resorting to rewinding or frequency converters?
You cannot run a three phase motor on single phase power. You'll burn the motor up within minutes. By the way, I've never seen or heard of a 380 volt motor. Do you mean a 480 volt motor? If so, the only way you can power it is with the correct full voltage and a 3 phase power supply.
What is a fractional electric motor?
Usually refers to a motor less than 1 horse power.
What would be the horse power required in a 3-phase motor to replace a .5 horsepower single phase motor.?
You still need the same horsepower. The advantage of the three-phase motor is that it will draw lower current.
What single phase motor should you use to get out the same power as a 3 phase one and a half HP motor It's going on a lathe and I don't want to find that a singel phase one and a half motor labors?
One And a Half Horse Power Obviously.
Can you replace a three phase motor 3 Hp RPM 1420 with a single phase motor for a planer?
Probably not. The single phase three horse power motor will be much larger in physical size than its three phase counterpart, and will probably not fit.
How many amps does a 50 horse power electric motor use?
Need to know the voltage of the motor.
How many current needed for the starting of a 5 horse power single phase motor?
120 volt
Why you use only single phase induction motor not other?
You would use a single-phase induction motor if the available electric power supply is a single-phase one. That applies to the average house or small business.
Which type of the motor is used in fan?
Low-power (a few watts) might use a synchronous motor, most fans use an induction motor. Above a couple of horse-power it might be a 3-phase induction motor.
Minimum breaker size 60 horsepower motor?
Need motor voltage, amperage and phase to give you an anwer.
What is the function of an electric motor in terms of electric power and motor?
The electric motor changes electric energy into mechanical energy.
How is a three phase agricultural motor used when there is no power supply?
With no three phase power supply you can't use a three phase motor of any kind at all!
Can you wire a 3 phase 690 volt delta star motor to 480 volt 3 phase with out harming the motor?
Depends on the motor and the load on that motor. If the motor is loaded to its capacity, it will draw the same amount of power as it would on 690 volts - which will result in ( 690/480 = ) 144% of normal current, which will thermally damage the motor, or will trip overload protection.
