Description

Technical Field

[0001] The utility model relates to the technical field of motor detection equipment, in particular to a testing device for a frameless motor. Background Art

[0002] Frameless motors consist of two parts: a stator and a rotor. Based on the spatial structure of the rotor and stator, they are categorized as either outer rotor or inner rotor frameless motors. Frameless motors lack a shaft connection between the stator and rotor. During motor testing, the stator must be mechanically connected to the fixed portion of the test fixture, and the rotor must be mounted to the rotating portion of the test fixture, ensuring that the stator and rotor are coaxial and capable of relative rotation.

[0003] In the prior art, there is a test device for a frameless motor, such as patent number CN217655258U, which includes a frameless motor body consisting of a stator and a rotor, and a base plate, wherein two groups of brackets are installed on the upper surface of the base plate, and the number of brackets in each group is two, and the top ends of the two brackets in the same group are installed with an annular fixed frame, and the upper and lower ends of the side surfaces of one of the fixed frames are installed with mounting plates; the test device for a frameless motor, by setting a fixing rod and a fixing frame, utilizes the ring-shaped fixing frame to place the frameless motor in the two fixed frames, wraps the outer side thereof, and drives the two movable plates to move relative to each other when the bidirectional threaded rod rotates. At this time, the fixing rod is driven by the movable plate to clamp and fix the frameless motor body, thereby fixing the frameless motor body in the fixed frame, which is convenient for later testing.

[0004] However, the test device for the frameless motor only involves fixing the frameless motor body through a fixing frame. When the frameless motor and the motor main control board need to be placed in the test device at the same time and the test data of the frameless motor is read through the motor main control board, it is difficult to fix the motor main control board, which makes it difficult to perform testing.

[0042] An embodiment of the present application provides a testing device for a frameless motor, which can solve the problem in the prior art that the testing device for a frameless motor only involves fixing the frameless motor body by a fixing frame. When the frameless motor and the motor main control board need to be placed in the testing device at the same time, and the test data of the frameless motor is read out through the motor main control board, it is difficult to fix the motor main control board, resulting in difficulty in testing.
