Abstract

An integrated direct-drive permanent magnet synchronous motor provided by the present invention comprises a linear motor assembly, a planetary reducer assembly and a control assembly, the linear motor assembly comprises a magnetic track assembly and a coil assembly, the magnetic track assembly comprises magnetic steel and a drum, the magnetic steel is located at the outer edge of the drum and is fixedly connected with the drum, and the coil assembly comprises a mounting seat, a silicon steel sheet and a coil. The silicon steel sheet is located on the inner edge of the mounting base and fixedly connected with the mounting base, the circumferences of the coils are inserted into the inner side of the silicon steel sheet at equal intervals to be fixed, the planetary reducer assembly comprises an inner meshing gear, a small outer meshing gear and a large outer meshing gear, the inner meshing gear is meshed with the small outer meshing gear, and the small outer meshing gear is meshed with the large outer meshing gear. The control assembly is used for detecting the rotating state of the motor and controlling the magnitude and frequency of current passing through the coil; the motor achieves the effects of energy consumption reduction and stable operation by controlling the current of the coil.

Description

technical field [0001] The invention relates to the field of motors, in particular to an integrated direct-drive permanent magnet synchronous motor. Background technique [0002] A synchronous motor is an AC motor that rotates at a synchronous speed by interacting with the excitation magnetic field of the DC power supply and the rotating magnetic field of the armature to generate torque. The power factor of the power grid, therefore, large equipment, such as large blowers, water pumps, ball mills, compressors, rolling mills, etc., are often driven by synchronous motors, and the speed of synchronous motors is only related to the power frequency f. Driving with the same amount of current does not make the motor achieve the best stability and the lowest energy consumption. [0003] The foregoing discussion of the background art is merely intended to facilitate an understanding of the present invention. This discussion does not endorse or acknowledge any part of the common kno...
