Description

Technical Field

[0001] This utility model relates to the field of servo motor testing technology, and in particular to an inertia testing device for servo motors. Background Technology

[0002] Moment of inertia is a measure of the inertia of a rigid body during rotation, and its magnitude reflects the ease with which the rigid body changes its state during rotation. The moment of inertia of a motor refers to the inertial resistance it experiences during rotation, and is an important parameter reflecting the motor's rotational capability. Therefore, inertial testing of servo motors is necessary. Because servo motors vary in size, power, and other factors, flexible installation and testing mechanisms are required. Currently, existing motor moment of inertia testing equipment, such as the Chinese utility model patent "CN220912558U, entitled 'A Servo Motor Inertia Testing Device'", includes a worktable with a first side plate and a second side plate on both sides of its upper surface; a bearing housing located between the first and second side plates; a rotating shaft passing through a bearing in the bearing housing; multiple inertia disks mounted on the rotating shaft; an auxiliary motor with its output end coaxially connected to the rotating shaft through a mounting hole in the first side plate; and a clamping assembly located on the second side plate for clamping the motor under test. This technology has poor flexibility and is applicable to a limited number of motor types and models.
