Description

Technical Field

[0001] The present invention relates to the technical field of mechanical engineering, and in particular to a novel multi-motor efficient, synchronous and stable driving system. Background Art

[0002] Dynamics and control in mechanical engineering is an important field that studies the motion and control of mechanical systems. It involves the motion laws and mechanical properties of mechanical systems and how to design and implement control systems to control the motion of mechanical systems. Dynamics: Dynamics is a discipline that studies the motion laws and force conditions of objects. In mechanical engineering, dynamics involves the kinematics and dynamics of mechanical systems. By analyzing the kinematics and dynamics of mechanical systems, we can understand the motion trajectory, speed, acceleration and force conditions of the system. Control system: A control system is a system used to control the motion of a mechanical system. In mechanical engineering, the design of a control system involves selecting appropriate sensors to obtain system status information, designing appropriate control algorithms to calculate control instructions, and applying control force or torque to the mechanical system through actuators. The control system can achieve position control, speed control or torque control as needed.

[0003] In mechanical engineering, most users use single-motor drives because they are simpler and more economical to design and install. Only one motor and a corresponding controller are needed to complete the drive task, reducing cost and complexity. At the same time, single-motor drives also have some disadvantages: in some applications, the load may be unevenly distributed on a single motor, which can cause the motor to be subjected to uneven loads, leading to overload or overheating. In addition, the power of a single-motor system is limited. Whether it is speed or torque, the output of a single motor may not meet the requirements of some high-performance applications. At the same time, if a single motor fails, the entire system may stop working completely, causing problems with the reliability and fault tolerance of the system.

[0004] Therefore, to address the above problems, we need to propose a new multi-motor efficient, synchronous and stable drive system. Summary of the invention
