Description

Motor inspection device and its control method {INSPECTION APPARATUS FOR MOTOR AND CONTROL METHOD THEREOF}

Embodiments of the present invention relate to a motor inspection device and a control method for inspecting whether there is an abnormality in the electrical performance of a motor in which a stator and a rotor are combined.

In general, electric vehicles, called eco-friendly vehicles, can generate driving force through an electric motor that obtains rotational force from electrical energy.

Electric vehicles drive in EV (Electric Vehicle) mode, a pure electric vehicle mode that uses only the power of the electric motor, or in HEV (Hybrid Electric Vehicle) mode, which uses both the engine and drive motor as power.

Most electric motors used as a power source for electric vehicles use permanent magnet synchronous motors (PMSM).

An electric motor, a permanent magnet synchronous motor used as a power source for such an electric vehicle, basically consists of a stator that generates magnetic flux, and a rotor that rotates and is disposed with a certain gap between the stator and the permanent magnet. .

Meanwhile, it is known that the output of an electric motor is proportional to the number of turns of the coil wound on the stator core. However, if the number of turns of the coil is increased, the size of the stator core or the electric motor itself including it inevitably increases, making miniaturization difficult.

Therefore, in order to improve output without increasing the size of the electric motor, the space factor of the coil wound on the stator core is increased. In other words, the dead space between the stator core and the winding coil or the dead space between each coil can be minimized to increase the coil space ratio.

Accordingly, recently, instead of using annular coils with a circular cross-section as coil windings, square coils such as square cross-sections (referred to as "segment coils" in the industry) have been used to reduce dead space and improve the space factor, thereby reducing the output compared to the same size. There is a trend to produce high electric motors.

In order to facilitate coil winding of the square coil, a plurality of separate hairpin-shaped (approximately U- or V-shaped) stator coils are inserted into the slots of the stator core, and stator coils are radially adjacent within the slots. A method has been proposed to allow all individual stator coils to conduct electricity by welding the ends of the stator coils.

Meanwhile, the stator is combined with the rotor to form a motor, and the motor can be equipped with a housing and commercialized.

Here, the motor is made into a final product through a separate inspection process. In the inspection process, the inspection terminal of the inspection facility is connected to each terminal of the motor and power is applied to inspect the performance of the motor.

However, in the past, workability and productivity were reduced because the test terminals of the test equipment and the terminal terminals of the motor were manually connected, and the terminal terminals could be damaged or cause injury to workers due to manual work.

Furthermore, in the related art, as the terminal terminals or the inspection terminals of the inspection equipment are deformed, it is difficult to ensure the reliability of the connection between the terminal terminals and the inspection terminals, and as a result, there is a problem in that the reliability of the motor performance inspection is reduced.
