Why the number of motor poles increased, the inverter capacity will increase
The power of the three-phase motor is equal to the root number of 3 times the line current and the line voltage of the product again good with the power factor. Can also be 3 times the phase current and phase voltage of the good product and then good to power factor.
The frequency converter should match the rated current of the motor, not the power of the motor.
The relationship between the motor current and the power is
The power is equal to the current and voltage of the product again good with the power factor. (Simplex)
The number of poles of the motor is not directly related to the rated current, but the number of poles is larger and the power factor is lower and the rated current will be higher.
