Electric Motor Power Measurement and Analysis Yokogawa ...

In order to calculate three-phase wattage, the voltage of each phase is multiplied by the current of each phase, which is then multiplied by the power factor, and this value is multiplied by the square root of three (the square root of 3 is equal to 1.732). To measure the three-phase power consumed by a loaded motor, a power analyzer is connected.

Calculations Simple Electric Motors - simple motor

You may calculate the resistance of your motor by 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 electrical power of the motor is defined by the following formula: P in = I * V. where P in – input power, measured in ...

For linear motion, power is the product of force and distance per unit time P = F (d/t). Since speed is distance over time, the equation becomes P = F s. In the case of rotational motion, the analogous calculation for power is the product of torque and angular distance per unit time or simply the product of torque and angular speed.
