How to calculate motor winding data?

To Calculate motor winding data, determine the motor’s specifications, including voltage, power, speed, frequency, and number of poles. Use the formula ( N_s = \frac{120f}{P} ) to find synchronous speed and calculate slots per pole per phase (SPP) as ( SPP = \frac{\text{Total Slots}}{\text{Poles} \times \text{Phases}} ). Decide on coil pitch (full or short-pitch) and calculate the number of turns per coil based on voltage and flux. Choose wire gauge based on current capacity, and ensure proper insulation and slot filling for efficiency and durability.
