Electrical Motor Calculator is a engineering tool to calculate amps, horsepower and kVa base on electrical motor formula.

Electrical Motor Calculator calculated values and are intended for use as a means of indicating expected values for electrical motor and similar product. Values will vary in service with load conditions, condition, age and type of motor.

Electrical Motor Calculator lets you figure out electrical characteristics of your system given a specific motor. By inputting horsepower, motor efficiency, power factor, and system voltage the system will calculate the amps, horsepower and kVa.

PF - Power Factor - three phase motors (0.0 - 1.0)
FLA - "Full Load Amps" - the amount of current when a motor is at its full rated out put power. FLA is the running load + 25%.
RLA - "Running Load Amps" - current drawn during normal operation of electric motor.
1 hp = 0.745 kW

*This is a universal app that work for both iPhone and iPad.

Read before you buy

I was looking for an app that would calculate motor efficiency. This app you already have to know efficiency and power factor and everything pretty much. It's a useless app. With ohms law you only need two variables and you can pretty much figure it out. I was just hoping this app would do the math for me, instead it just took $2.99 of my money :-/
