Motor slip percent

Calculates slip from synchronous speed and rotor speed.

Calculates motor synchronous speed from frequency and pole count.

Calculates approximate torque from power in kW and rotational speed.

Calculates back EMF from supply voltage, armature current and armature resistance; with a back-EMF constant it also gives angular speed.

Calculates current and torque at zero back EMF in a simple armature model.

Calculates approximate three-phase motor current from power, voltage, power factor, and efficiency.
