Description

technical field [0001] The invention relates to an energy feedback type linear motor test loading device, which belongs to the technical field of motor testing. Background technique [0002] In the field of modern processing industry, many occasions such as laser cutting, high-speed grinding machines, precision lathes, machining centers, etc. require high-speed and high-precision linear motion, while traditional methods can only be obtained by means of intermediate links such as rotating motors and ball screws. Linear motion, which inevitably has disadvantages such as large inertia, large friction, and backlash. In recent years, with the advancement of linear motor technology, more and more occasions have begun to directly apply it to obtain linear motion. Due to the use of direct drive technology, linear motors have the advantages of fast speed, high acceleration, high positioning accuracy, long stroke and fast dynamic response, which just meet the requirements of high-spe...
