Magnetic circuit structure of high-performance permanent magnet synchronous servo motor for intelligent device

The invention provides a magnetic circuit structure of a high-performance permanent magnet synchronous servo motor for an intelligent device. The magnetic circuit structure comprises a stator punching sheet, a rotor punching sheet and magnetic steel. The rotor punching sheet is sleeved in the stator punching sheet; the magnetic steel are arranged in the rotor punching sheet; and the stator punching sheet is in a circular ring shape. The inner wall of the stator punching sheet is provided with 12 stator slots in uniform-angle distribution along the circumference. The opening width of each stator slot is 4.2 mm; the slot depth of each stator slot is 22 mm; and the tooth width between adjacent two stator slots is 17.9 mm. The rotor punching sheet is provided with 10 magnetic steel installation grooves in uniform-angle distribution along the circumference. Each installation groove is internally equipped with matched magnetic steel; the magnetic bridge width of the rotor punching sheet is 1 mm; the thickness of the magnetic steel is 6.3 mm; and the aperture angle of the magnetic steel is 32.4 degrees. The magnetic circuit structure has high-power-density electromagnetic performance, can realize small size and light weight in actual application, and is easy to realize high-precision control and high output power.
