Searching for the possibility of buying a 40A 12V DC suction fan. I have a project that requires 0.63HP that can be supplied by a 12V DC battery. Please how do I do this?

 

Too vague, what supply do you have for this motor? Is it just on/off control or other?
12v 40a is close to .63HP how accurate do you need to be on sizing?
Max.

Thank you dear for your concern
Actually by calculation I need 39A to be used by the DC suction fan to so that the cooling power of 0.63hp will be met. But why I said 40A is because of factor of safety. I will be making use of 12V DC battery i.e the battery used in car and motorcycle for the supply for the motor.

 

A few of these will get you to 40 A. But not much relation to 'cooling' power.
