### How to Calculate Power Consumption of an Electric Motor

Calculating power consumption for an electric motor is an important step in understanding its efficiency and determining the associated costs. This guide will walk you through the process of calculating power consumption, providing a clear explanation and some frequently asked questions at the end.

#### Step 1: Gather the Required Information

Before diving into the calculations, ensure you have the necessary information:

• Motor Power (P): The rated power of the motor, usually expressed in kilowatts (kW).
• Line Voltage (V): The voltage at which the motor is connected, typically given in volts (V).
• Line Current (I): The current drawn by the motor, usually measured in amperes (A).
• Power Factor (PF): The power factor of the motor, which indicates the efficiency of electrical power utilization. It ranges from 0 to 1.

#### Step 2: Calculate Power Consumption

The formula for calculating power consumption (PC) is:

```    PC = P / (PF * √3 * V * I)
```

Where:

• P: Motor Power
• PF: Power Factor
• V: Line Voltage
• I: Line Current
• √3: Square root of 3 (a constant value for three-phase power calculations)

By plugging in the values of P, PF, V, and I, you can calculate the power consumption of the electric motor.
