App Store Description

Electric Motors Power Torque Speed Calculator are physic/math calculator to find electric motor power, torque or speed fast and easy.

Features:
- Instant calculation
- Result are copy able to other app
- Formula are include as reference
- Support up to 16 decimal place
- Support various unit for each input


The Speed for an electric motor in SI units can be calculated as
n = f x ( 2 / p ) x 60

The Torque for an electric motor in SI units can be calculated as
T = P x 9.549 / n

Where:
T = torque (Nm)
P = power (watts)
n = revolution per minute (rpm)
f = frequency of electrical power supply (Hz, cycles/sec, 1/s)
p = number of poles

The speed for an electric motor is determined by power supply frequency and the number of poles in the motor winding. The torque is the twisting force and also is the driving force of an electric motor. The power produced by the motor is depends on the speed of the motor. Which is zero at 0% speed, and normally at it's top at 100% speed.


On an induction motor, the number of poles determines the speed given the frequency of the power.
For example, a 2 pole motor on 60 Hz equal to
RPM = 60*(2/2)*60
RPM = 3600 rpm
a 4 pole motor on 60 Hz equal to
RPM = 60*(2/4)*60
RPM = 1800 rpm
for 6 pole, 1200 rpm and so on.
As speed decreases, the torque increases so an 8 pole motor has 4x the torque compare to 2 pole motor with 1/4 the 8 pole motor speed.

*60Hz is the most common frequency in the US
*50Hz is the most common frequency outside the US




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