        This paper describes the design features and energy-saving advantages of special variable-frequency low-voltage three-phase induction motors,discusses the method of setting reference voltage and reference frequency of frequency inverter according to the mechanical characteristics of load and the parameters of motor,and states that setting reference voltage and reference frequency of frequency inverter is the basis to fully use frequency inverter and meet frequency inverter requirements of load. The correctly-set ratio of voltage to frequency of frequency inverter is the key to use variable-frequency motor and frequency inverter. At the same time,it is expounded that the low-voltage variable-frequency motor should comprehensively apply and collectively consider various control technologies to save energy,and then achieve the maximum level of energy saving and efficiency improvement.
