Abstract

The invention relates to a high-speed magnetic levitation linear eddy current brake system and belongs to the motor field. The invention aims to solve the problem that an existing magnetic levitationlinear eddy current brake system requires a special levitation and guide control device. The high-speed magnetic levitation linear eddy current brake system of the invention comprises a stator and a mover; the stator comprises levitation guide primary windings and stator conductor plates; the mover comprises mover magnetic poles; a plurality of coil sets are sequentially arranged along the movingdirection of the mover and fixed on a coil substrate; each coil set is composed of two rectangular coils of which the winding directions are opposite to each other; the two rectangular coils are arranged along a horizontal direction and are perpendicular to the moving direction of the mover; the rectangular coils are connected with one another end to end; the stator conductor plates are located between the two rectangular coils; and the stator conductor plates are vertical to the ground; the mover magnetic poles are located above the levitation guide primary windings and are aligned with the levitation guide primary windings; and air gaps are left between the mover magnetic poles and the levitation guide primary windings.

Description

technical field [0001] The invention belongs to the field of motors. Background technique [0002] The braking performance of the friction braking device using frictional force becomes worse at high speed or ultra-high speed; energy regenerative braking can also provide braking force at high speed, but it requires a large-capacity electric energy storage device and a power electronic control device, and there are Reliability issues such as power outages and disconnection out of control. Therefore, the development of high braking force density and high reliability braking device is very important for high-speed motion system. [0003] Permanent magnet eddy current braking is a new type of braking technology developed in the 1990s. It uses the relative motion between the permanent magnet magnetic field and the conductor plate, and generates a strong eddy current in the conductor plate, as well as the eddy current magnetic field and the permanent magnet. The interaction of th...
