AC/DC intelligent high-efficiency energy-saving motor and driving method thereof

Abstract

The invention discloses an intelligent efficient and energy-saving AC / DC motor and a driving method thereof. The intelligent efficient and energy-saving AC / DC motor comprises a rectifying module, a recurrent pulse generating module, a rate regulation and control module, an excitation pushing module, a power driver module, a motor and an induction output module, and has the advantages that the electricity consumption is low, the power is high, no high-current impact is caused to the grid when the motor is started up, the high and low speeds of the motor can be subjected to continuous electrodeless adjustment, the output torque force of the motor is 4.8 times of that of a traditional motor at the same electricity consumption, the load heating of the motor is small, the energy-saving rate of the motor is 60% of that of the traditional motor at equal electricity consumption, the lock-rotor can not be burnt out, the anti-interference performance is strong, the self-safety protection function is achieved, the service life is long, and the cost is low and the application range is wide. During load operation of the motor, the motor can output 10-40 percent electrical energy to an external load so as to achieve outward power supply, realizes multiple functions, is convenient and safe in use, and achieves the purposes of low cost, resource saving and energy saving.

Description

technical field [0001] The invention relates to the field of motors, in particular to an AC / DC intelligent high-efficiency energy-saving motor and a driving method thereof. Background technique [0002] Existing AC motors, brushed DC motors, and brushless DC motors in the prior art are widely used in people's daily production and life, and have been used in household appliances, enterprises, electric vehicles, electric bicycles, and automation equipment. The unfavorable factors of the existing motors used in various industries are: high energy consumption, low power conversion efficiency, high power consumption and small torque, non-proportional energy consumption and torque, high invalid energy consumption, low power factor, and The no-load power consumption is 65% of the load power consumption. There is a lot of waste of power, low power, high operating temperature, easy damage to the motor stall, loud motor operation noise, and short service life. Especially the tradition...
