[0002] The brushless DC motor consists of a motor body and a driver, and is a typical mechatronics product. Since the brushless DC motor is operated in an automatic manner, it does not require an additional starting winding on the rotor like a synchronous motor that starts under heavy load under variable frequency speed regulation, nor does it produce oscillation and loss of step when the load changes suddenly.
[0003] Blades are components of brushless DC motors and are in the shape of sheets. Blades used in some precision machinery not only have strict requirements on the length accuracy of the blades at room temperature, but also have strict requirements on the length change of the blades when the heat generated when the blades rotate at high speed causes the blades to expand. Therefore, it is necessary to detect the length of the blades after rotation and heating. When detecting the blades, a fixture is needed to fix the blades. Therefore, a fixture with multiple limit structures is required.
