The magnetic tiles 140 are multiple pieces, and the multiple pieces of magnetic tiles 140 are adhered to the inner wall surface of the casing 110 along the same circumference. When actually bonding the magnetic shoe 140, the magnetic shoe 140 is prone to have a problem of being higher or lower in the position of the mounting cavity 120, and then generates a defective product, and the motor magnetic shoe thrust testing device in this embodiment can be used for performing thrust test on the magnetic shoe 140 of the motor 100, and then kicks out a defective product in the production process of the motor 100.
Referring to fig. 2 to 3, the motor magnetic shoe thrust testing apparatus in the present embodiment includes a bracket 10, a force measuring assembly 20, and a force application assembly 30.
