Power Consumption (Annual) = Power Usage (Watts) x Time (Hours) x 365 (Days) Example: A 1700 Watts Electric kettle runs for 1 hours daily. Calculate the energy consumption in Wh and kWh in one year. Annual power usage in Wh = 1700W x 1 Hours x 365 days= 620500 Wh / year; Annual power usage in kWh = 620500 Wh /1000 = 620.5 kWh / year

DetailsYou maycalculatethe resistance of yourmotorby measuring the consumed current and applied voltage. For any given resistance (in the motors it is basically the resistance of the coil) this formula explains that the current can be controlled by applied voltage. The consumed electricalpowerof themotoris defined by the following formula: P

DetailsThe power rating of the motor in kW. Power factor (cosΦ). The rated power factor of the motor. Typically around 0.86. Efficiency (η). The efficiency of the motor. Typically around 95%. Enter 0.95. The motor current is calculated as follows. For a 3-phase supply with power rating in kilowatt (kW): For a 3-phase supply with power rating in horsepower (hp):

DetailsOutput mechanical power of the motor could be calculated by using the following formula: P out = τ * ω. where P out – output power, measured in watts (W); τ – torque, measured in Newton meters (N•m); ω – angular speed, measured in radians per second (rad/s). It is easy to calculate angular speed if you know rotational speed of the motor in rpm:

DetailsMultiplying both sides of Voltage Equation (1) by I a, we get the power equation of a DC motor as follow. VI a = E b I a + I a 2 R a ….. (2) Where, VI a = Input Power supply (Armature Input) E b I a = Mechanical Power developed in Armature (Armature Output) I a 2 R a = Power loss in armature (Armature Copper (Cu) Loss) Related Posts:
