Description

Technical Field

[0001] The utility model relates to the field of encoder testing equipment, in particular to an encoder durability testing device. Background Art

[0002] An encoder is a device that converts angle or displacement information into electrical signals for transmission and communication. The encoder's main shaft is fixed to the rotor of the object being measured, while the encoder body is fixed to the stator. Rotation of the rotor drives the encoder's main shaft. This prolonged rotation wears the encoder. To test the encoder's service life and its condition after extended operation, a rotating device is required to rotate the encoder. Existing testing equipment often relies on a motor to drive a single encoder, resulting in low efficiency. Therefore, it was necessary to develop an encoder durability test device to address these issues. Utility Model Content
