Title:
DIRECT DRIVE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/000700
Kind Code:
A1
Abstract:
The present invention provides a direct drive system, comprising a stator, a primary assembly, a rotor, a secondary assembly, and a first magnetic yoke. The first magnetic yoke is provided on one side of the stator, and the primary assembly is provided on the first magnetic yoke; the rotor is provided with a first supporting surface and a second supporting surface; the first supporting surface and the second supporting surface are respectively provided on two opposite sides of the stator; the secondary assembly is provided on the first supporting surface and faces the primary assembly; a first gap is formed between the secondary assembly and the primary assembly; a magnetic field loop is formed among the secondary assembly, the primary assembly, and the first magnetic yoke; and the side of the stator distant from the first magnetic yoke faces the second supporting surface, and the second supporting surface is used for supporting a worktable surface. The direct drive system is reasonable in structural design, can well protect the primary assembly and the secondary assembly, and is high in stability and reliability.
