I'm revising for an exam and i’ve come across these equations in my lecture notes.(adsbygoogle = window.adsbygoogle || []).push({});

Has anyone seen these equations before, and can tell me what the symbols represent?

T = k1 ᶲ Ia

Ea = k1ᶲ2πN = k2ᶲN

Ea = Va-IaRa

N = (Va-IaRa) / (2πk1ᶲ)

Im guessing T is torque, Ea is the volatge across the motor, and Va is the source voltage. Im not sure though.

Thanks

Edit:

The π symbol is pi
