Title:
MAGNETICALLY LEVITATED LINEAR ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2020/134659
Kind Code:
A1
Abstract:
Disclosed is a magnetically levitated linear electric motor, which can solve the problem in existing magnetically levitated linear electric motors of safe railway operation being affected due to primary stator cores being likely to scratch upwarped ends of aluminium plates on the surface of a track during a railway operation process. The electric motor comprises a primary portion mounted at the bottom of a compartment of a magnetically levitated train, and secondary portions laid on the surface of a track, wherein the primary portion comprises a stator core (1) and several winding coils (2) embedded in the stator core (1); the secondary portions are several sections of aluminium plates (3) that extend in a lengthwise direction and are sequentially assembled and laid on the surface of the track; the stator core (1) comprises several stator punching sheets (4); after being stacked, the several stator punching sheets (4) are connected via a locking bolt (5) and a locking nut (6) in a fastening manner; two end angles in the lengthwise direction of the bottom of each of the stator punching sheets (4) are both rounded or beveled angles; and two ends in the lengthwise direction of the bottom of the stator core (1) formed after the several stator punching sheets (4) are stacked and are fastened by the locking bolt (5) are both first circular arc end faces (8) or beveled end faces (30).
