Need to know the voltage and phase for this question.
Need to know the horsepower of the motor.
Divide by 60.
HP/.00134= Watts Then Watts divided by Volts = AMPS For expample. a .75 HP electric motor running on 220VAC uses 2.544 amps .75 / .00134 = 559.7015 Watts then 559.7015 / 220 = 2.544
hi.. this is pankaj working as power engineer. we have a 11 kw induction motor which is used in fluidising blower. its no load current i sarround 9.5 to 10.6 amp. and under load its ampere does nt exceed 15 amp. its winding resistance is 1.4 ohm.
The RPMs of a D.C. motor will vary depending on the torque required for the application. The more torque required the slower the RPMs. Higher torque requirements will also increase the AMP draw of the motor. Other reasons the RPMs can vary is heat build up, low voltage of batteries, cable size, connection condition and others. You need to make sure your connections are clean, the cables are thick enough to handle the AMP load and your batteries are fully charged for peak performance.
The 40 amp motor probably produces double the horsepower of the 22 amp motor.
Need to know the horsepower of the motor.
How to convert horsepower to amps? You'd have to make an assumption about volts. If it's running at 220 volts, that would make it 34 Amps. There are 746 watts in a horsepower and Amps = Watts/Volts.
A breaker is based on the amount of current that the motor draws. This amperage should be taken off of the motors nameplate. In motors of a specific horsepower the amperage is proportional to the voltage the motor uses. Without the motors voltage this question can not be answered.
1 horsepower = 746 watts, 1 watt = 1 volt x 1 amp => 20 Horsepower = 14,920 watts => 14,920 watts / 220 volts = 67.82 amps
This is the formula for horsepower. HP = I x E x 1.73 x %eff x pf./746. The efficiency of the motor will have to be guessed at along with the power factor. A motor has a lagging power factor so will use a value of .85. For the efficiency of the motor lets say 90%. The value of 746 is the amount of watts in one horsepower. Now applying the values we end up with a HP value. HP = 1.7 x 480 x 1.73 x 90 x .85/746 = 1080/746 = 1.45 horsepower.
At peak power it should draw 1.36 amp at power factor 1 or more realistically 1.7 amp at power factor 1.7.
Divide by 60.
To calculate the HP of a motor, you can use the formula: HP = (Watts x Efficiency) / 746 Where Efficiency is a typical value between 0.7 and 0.9. For a 3 amp motor, you will need to know the voltage to calculate the wattage and then convert it to HP using the formula above.
No, a 6 amp switch should not be used to control a 12 amp motor as it may cause the switch to overheat and fail due to exceeding its amperage rating. It is important to match the switch's amperage rating with the motor's amperage to ensure safe and proper operation.
To answer this question a voltage is needed. 1 HP = 746 Watts. Amps = Watts/Volts.
