How do you calculate energy consumption of a motor?
Calculate the power the motor consumes while in operation. The equation is W = AV(sqrt 3) where A is amperes, V is volts, and sqrt 3 is the square root of 33 (about 1.73). W is the power consumption in watts. For example, if the electric motor uses 50 amps at 240 volts, the wattage is 50 x 240 x 1.73, or 20,760 watts.
What is the formula of motor?
Electric Motor Formula
| TO FIND | DIRECT CURRENT | THREE PHASE |
|---|---|---|
| CURRENT | P V x EFF | P 1.732 x V x EFF x PF |
| EFFICIENCY | 746 x HP V x I | 746 x HP 1.732 x V x I x PF |
| POWER FACTOR | —— | Input Watts 1.732 x V x I |
| SHAFT SPEED | —— | 120 x F no. of poles |
How do you calculate the force of a motor?
To calculate the force required to move the object: F = m * g *u , F = force, m = mass of object, g = gravity constant, u = friction. F = 500 kg * 9,82m/s2 * 0.8 F = 3924 N to push the object.
How is BHP calculated?
Formula for calculations of Break horsepower is
- BHP = (Torque × RPM )/5252,where torque is lb -ft and n = revolution per min.
- BHP = BP /33000,where BP (in watt ) = Torque×2π×RPM (RPM in min. ) Where torque in the formula of BP is in lb -ft.
- BHP =BP (in Watt ) / 746 we get it in horse power ,since 1 HP = 746 watt.
How to calculate the electrical power of a motor?
The consumed electrical power of the motor is defined by the following formula: Pin = I * V. where Pin – input power, measured in watts (W); I – current, measured in amperes (A); V – applied voltage, measured in volts (V). Motors supposed to do some work and two important values define how powerful the motor is.
How much power does a 1 hp motor have?
Power is the rate at which work is done. A 1 HP motor can be expected to perform the work of 1 horse, or the power to move a 550 lb. load 1 foot in 1 second. 1 HP = (550 lb. * 1 ft.)/sec. The electrical equivalent of 1 HP is 746 Watts.
What do you need to know about motor sizing?
Motor Sizing Calculations There are three factors to calculate when sizing a motor; Moment of Inertia, Torque, and Speed.
How much power does a 3 phase motor use?
The above calculations are suitable for DC motor, AC single phase motor and 3 phase motor. Calculate the total power consumption of the 3 Phase 30HP motor is operating for 38 days at 70% of the full load and the motor is operated at 14 hours per day.
