1. Fully understand the performance requirements of the control object. Generally speaking, if the starting torque, speed regulation accuracy, and speed regulation range are required to be high, it is necessary to consider the use of a vector inverter. 2. Understand the main nameplate parameters of the motor used: rated voltage, rated current. 3. Determine the maximum current that may appear in the load, and use this current as the rated current of the inverter to be selected. If the current is less than the rated current of the adapted motor, select the corresponding inverter according to the adapted motor, considering the cost factor. 4. The following situations should consider increasing the capacity by one gear: 1) Long-term high temperature and high load 2) Sites where abnormal or faulty shutdowns will have catastrophic consequences 3) Large fluctuations in the target load 4) The on-site power grid is long-term low and the load is close to the rated 5) Wound motors, synchronous motors, or multi-pole motors (more than 6 poles).
