Web6 jan. 2024 · If we have the motor of the following specifications: 25 HP, 60 Hz, 480 V, 3 Phase, 0.8 p.f, 89% efficiency at full load. Which of the below formula should we use to calculate the Full Load Current? Motor Full Load Current = (0.746 x 25 x 1000) / … WebEfficiency is always mentioned in percentage % η = P o x 100 / P i. P i in watts is equal to the product of input voltage V i in volts input current I i in amps. P i = V i x I i. This is the basic formula for motor efficiency calculation. DC motor efficiency: Let us take Motor Output = V x I. Motor Input = motor output + Loss
WebThe input power from equation (1) is the electrical power of the battery. From equation (1) we can calculate the electrical power P e [W] as: where: P m [W] – motor (mechanical) power. η m [-] – motor efficiency. Also, the electrical power is the product between voltage and current: where: U [V] – battery voltage.
