Problems solved by technology

However, the use of servo motors in existing equipment is not sufficient. Positioning under servo drive is only realized at low operating speeds. Equipment operating at high speeds is prone to errors. In order to ensure accuracy and increase speed, large motors are generally used The rated power of the servo motor is used to make up for it, resulting in high energy consumption and low efficiency. At the same time, the traditional servo drive device needs reducers, gears, synchronous belts, couplings and other mechanisms to act on the equipment rollers, and only uses independent servo motors to drive , the efficiency still cannot meet the needs of high-speed and automated intelligent production

Description

technical field [0001] The invention relates to the field of servo motors, in particular to a coaxial servo drive device. Background technique [0002] With the increasing precision of processing technology in the current production environment, intelligent production also has new requirements for processing accuracy and processing efficiency, especially for high-speed processing equipment with strict requirements on the circumferential position and motion curve of the roller. Therefore, many devices need to be driven by servo motors to achieve this effect. However, the use of servo motors in existing equipment is not sufficient. Positioning under servo drive is only realized at low operating speeds. Equipment operating at high speeds is prone to errors. In order to ensure accuracy and increase speed, large motors are generally used The rated power of the servo motor is used to make up for it, resulting in high energy consumption and low efficiency. At the same time, the tr...
