Electrical Motor Calculator is an engineering tool to calculate amps, horsepower, kilowatt 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, kilowatt, motor efficiency, power factor, and system voltage the system will calculate the amps, horsepower, kilowatt and kVa. PF - Power Factor - three phase motors (0 - 100%) or (0.0 - 1.0) FLA - "Full Load Amps" - the amount of current when a motor is at its full rated output power. FLA is the running load + 25%. RLA - "Running Load Amps" - current drawn during normal operation of electric motor. 1 kVA = 1,000 volt amps Kilowatts to horsepower conversion 1 HP = 0.7457 kW 1 kW = 1.34102 HP Thanks for your support and do visit nitrio.com for more apps for your iOS devices.

Verdict

The call

The clearest difference is price: Electrical Calculations at Free against Electrical Motor Calculator's $2.99. Electrical Calculations also leads on rating (4.6 vs 3.8) and update cadence (every 2 weeks vs every 43 months). Electrical Motor Calculator's advantage is in-app purchases (none vs 3) and ads (none vs shown). On device support there is nothing between them.
