Description

Technical Field

[0001] The utility model relates to the technical field of direct-drive motor transmission, in particular to a transmission component for a direct-drive motor. Background Art

[0002] Direct drive motor, also known as direct drive motor, is a new type of motor drive technology. In traditional motor drive systems, motors are usually used to drive loads through intermediate transmission mechanisms such as belts, chains, gears, etc. However, there are many problems with these intermediate transmission links, such as reduced transmission efficiency, precision loss, high noise, high maintenance cost, and large space occupation. With the continuous advancement of science and technology and the increasing demand for high-precision, high-speed, and high-efficiency drives, direct drive motors came into being. Direct drive motors directly transmit the power of the motor to the load, eliminating the intermediate transmission link, thereby achieving higher precision, faster response speed, lower noise, and higher transmission efficiency. The emergence of direct drive motors is largely due to the development of materials science, power electronics technology, control theory, and manufacturing technology. For example, the application of high-performance magnetic materials enables motors to generate stronger magnetic fields, improving the power density and efficiency of motors; advanced power electronics and control algorithms enable precise control and optimized operation of motors; and precision manufacturing processes ensure the manufacturing accuracy and reliability of motors.

[0003] The transmission components of a direct-drive motor are relatively simple, mainly including: The motor body: This is the core component of the direct-drive motor, which directly generates rotational power. Encoder or position sensor: Used to detect the rotational position and speed of the motor and provide feedback information for precise control. Connecting components: Such as couplings, flanges, etc., used to mechanically connect the motor to the driven load. However, the existing couplings have a single function and cannot be changed according to the environment, which is too limited. Utility Model Content
