Core Concepts Deep Dive
A brief overview of the key parameters that determine a motor's power consumption and output.
⚡ Voltage (V)
The electrical "pressure" in a circuit. For 3-phase motors, we use Line-to-Line Voltage ($V_{LL}$), the potential between two power conductors.
🌊 Current (I)
The "flow rate" of electricity. We measure Line Current ($I_L$), the amount of current flowing through a single power conductor.
🍺 Power Factor (cos φ)
A measure of efficiency, from 0 to 1. It's the ratio of working power (kW) to total power (kVA). A lower value means more wasted energy.
⚙️ Efficiency (η)
The motor's ability to convert electrical energy into mechanical work. It's never 100% due to heat and friction losses.
