Abstract

The invention discloses a high-speed magnetic suspension linear propulsion system, and belongs to the field of motors. The high-speed magnetic suspension linear propulsion system aims at solving the problems that an existing magnetic suspension propulsion system is poor in stability and complex in control. The propulsion system comprises a motor device and a driving control device. The motor device is mainly formed by a primary part and secondary parts. The primary part is mainly formed by a suspension part, a primary guide part and a primary propulsion part. Each secondary part is mainly formed by a rotor base plate and a secondary unit. Each secondary unit is fixed to the corresponding rotor base plate and is mainly formed by a permanent magnet and a secondary base plate. The driving control device is used for generating a driving signal and transmitting the driving signal to the primary part to achieve driving control. According to the high-speed magnetic suspension linear propulsion system, as suspending and guiding are adapted and stabilized by itself, and a special suspending and guiding control device is not required, control is easy, safe and reliable, cost is low, and running efficiency is high. Suspension and guide air gaps are large, suspending and guiding are stable, and the harsh requirement for the building accuracy of a guide rail is avoided.

Description

technical field [0001] The invention belongs to the field of motors. Background technique [0002] The existing high-speed maglev linear propulsion system can be divided into two categories: normal conduction type and superconduction type. The constant conduction type is also called the constant conduction magnetic suction type, represented by the German high-speed constant conduction maglev train transrapid, which uses the principle of electromagnetic attraction of ordinary DC electromagnets to suspend the train, and the suspended air gap is small, generally about 10mm. The speed of the conventional high-speed maglev train can reach 400-500km per hour, which is suitable for long-distance rapid transportation between cities. The superconducting magnetic levitation train is also called superconducting magnetic repulsion type, represented by MAGLEV in Japan, which uses the strong magnetic field generated by superconducting magnets, and interacts with the coils arranged on the...
