Since the motor has high power, the cross-sectional area of the cable used must be large as well.
Method for determining cable size based on motor power: 1. Using the power formula P=1.732UIcosφ, the rated current I of the motor can be calculated as I=P/(1.732Ucosφ). 2. Determine the size of the cable based on the current value. There are two methods for determining the cable size based on the current value: 1. Table lookup method. (Determine the cable size by referring to the table below) 2. Calculation method.
Error. In addition to power, factors such as cable material also need to be considered.
