Synchronous Speed

An electric motor is an electrical machine that converts electrical energy into mechanical energy. A synchronous electric motor is an AC motor distinguished by a rotor spinning with coils passing magnets at the same rate as the AC and resulting in a magnetic field that drives it.

The motor speed equals 4\[Pi] times the supply frequency divided by the number of poles.

Formula

QuantityVariable[Subscript["ω", "S"], "AngularFrequency"] == (4*Pi*QuantityVariable["f", "Frequency"])/QuantityVariable["P", "Unitless"]

symbol description physical quantity
ωS motor speed "AngularFrequency"
f supply frequency "Frequency"
P number of poles "Unitless"
