A Novel Suspension Electromagnet Unit and Suspension Electromagnet Module

Abstract

The invention discloses a novel suspension electromagnet unit and a suspension electromagnet module. The novel suspension electromagnet unit includes an inner pole plate and an outer pole plate arranged oppositely. An iron core and a coil are arranged between the inner pole plate and the outer pole plate. The iron core includes a first iron core and a second iron core that are vertically and evenly distributed in the longitudinal direction of the inner pole plate and the outer pole plate, and the coil includes a first coil and a first coil that are sleeved on the first iron core or the second iron core and arranged oppositely The second coil or the third coil and the fourth coil, the first coil, the second coil, the third coil and the fourth coil are connected in series or in parallel to form a circuit of a new suspension electromagnet unit, and the suspension electromagnet module includes Two independent new suspension electromagnet units, the new suspension electromagnet unit and the suspension electromagnet module of the present invention have a certain redundancy function, when a coil or drive circuit in the new suspension electromagnet unit fails, by adjusting the drive circuit Voltage, which can ensure the normal operation of the new suspension electromagnet unit.

Description

technical field [0001] The invention relates to the field of maglev trains, in particular to a novel suspension electromagnet unit and a suspension electromagnet module. Background technique [0002] At present, the suspension electromagnet module includes two suspension electromagnet units, and each suspension electromagnet unit is composed of two integral pole plates, two iron cores and two coils. The coils are connected in series to form the circuit of the suspension electromagnet unit. The driving circuit in the suspension controller includes two half-bridge chopper circuits, which respectively drive the two suspension electromagnet units in the suspension electromagnet module. The voltage in the suspension electromagnet unit is , the current is , used to supply power to the suspension electromagnet module. The design of the suspension electromagnet unit and the suspension electromagnet module has the following deficiencies at present: [0003] ① When any coil is da...

AI Technical Summary

Problems solved by technology

[0003] ① When any coil is damaged or the drive circuit fails, the suspension electromagnet unit cannot work, resulting in the failure of the entire suspension electromagnet module;

[0004] ② When the load of the maglev system is large, the current is large, resulting in large Joule heat, the temperature of the levitation electromagnet rises, which affects the characteristics of the electrical system, and may even cause damage to the levitation electromagnet in severe cases
