hello sirs,
i want to know a 1HP motor takes how much of current in no load and full load.
You must provide many more information with the question if you are an electrical person (if at all)
- Motor is ac or dc ?
- if ac then no. of phases of motor
- Volatge across which it is to be connected
- efficiency of motor
- if ac then pf
and if you shall provide all these information being an electrical person, you must be having answer to your question
1 HP is 746 watts at 100 % efficiency. Amperes = Watts / Voltage
Efficiency of electric motors is usually around 85 %, so 1 HP at motor shaft will require about 18 % more current.
....And there is always the nameplate information on the motor, or information available from the manufacturer.
