Output Power of DC Machine Formula Elements

Variables

Output Power

Output Power refers to the product of current and voltage at the output terminal of a dc generator.

Symbol: P_o

Measurement: PowerUnit: W

Note: Value can be positive or negative.

Formulas to find Output Power

Angular Speed

Angular speed is the rate of rotation about an axis, measuring how the angle changes with time. It is measured in radian/sec.

Symbol: ω_s

Measurement: Angular VelocityUnit: rad/s

Note: Value should be greater than 0.

Formulas to find Angular Speed

Torque

Torque is the measure of the turning force produced by the armature. It is produced by the interaction between the magnetic field of the stator and the current flowing through armature.

Symbol: τ

Measurement: TorqueUnit: N*m

Note: Value can be positive or negative.
