Title:
INTEGRATED ELECTROMAGNET AND MAGLEV TRAIN
Document Type and Number:
WIPO Patent Application WO/2021/190118
Kind Code:
A1
Abstract:
An integrated electromagnet and a maglev train. The integrated electromagnet comprises two rows of magnetic poles located on the side surface of a magnetic yoke (1) facing a guide plate. The two rows of magnetic poles are in one-to-one correspondence. The axes of magnetic cores (21) in the magnetic poles are perpendicular to the side surface of the magnetic yoke (1) facing the guide plate (11). The magnetic poles comprise first magnetic poles (2) and second magnetic poles (3), and the first magnetic poles (2) and the second magnetic poles (3) in the same row of magnetic poles are arranged alternately. The first magnetic poles (2) in either row of magnetic poles are adjacent to the second magnetic poles (3) in the other row. The second magnetic poles (3) in either row are connected in series and connected to a bidirectional output controller (5). In a guide state, the magnetic poles in the same row have the same polarity, and the polarity of one row of magnetic poles is opposite to that of the other row of magnetic poles. The direction of current outputted by the bidirectional output controller (5) in a brake state is opposite to that of current outputted in the guide state. Integrating a braking function and a guiding function into one integrated electromagnet can reduce the waste of brake electromagnet resources.
