A motor‑car is a vehicle equipped with a power unit in the rail transit system. The electric motor serves as its main power device, which provides driving torque and acts as the power source for electrical appliances and various types of machinery. It converts mechanical energy into electrical energy. The customer’s product is an electric motor for motor‑cars. The assembly requires extremely high accuracy of hole alignment. Therefore, the position and diameter of the motor mounting holes are measured, and the obtained data are analyzed to check for deviations so as to avoid problems during assembly.

        The motor has a relatively complex outer shape. The main items to be measured include hole spacing, diameter and the distance of the intermediate shaft. It places high requirements on the equipment used. The measurement data features small precision errors and can accurately reflect existing problems.

The Holon 3D Hand‑Held 3D Scanner Model 29 delivers a scanning accuracy of up to 0.02 mm. It features a single‑line deep‑hole scanning mode with 29 laser beams. Boasting a fast scanning speed, it can easily handle scanning tasks for high‑speed train traction motors. The scanned data can be imported into 3D inspection software for comparative analysis, after which easy‑to‑understand inspection reports can be exported. This allows customers to view all data clearly, make judgments, and formulate corresponding solutions.

The hand‑held 3D scanner enables convenient and efficient scanning and data acquisition, providing substantial assistance to customers and satisfying their requirements.
