“…It has been found that there are not many published research results on data acquisition systems, and four studies have been carried out to develop data acquisition systems [9], [20], [21], [22]. In [9] and [20], data acquisition systems were proposed for AC servo motor drives that require high data transmission rates, and in [21] and [22], for general applications without considering transmission rates.…”

“…In [20], a hardware and software solution for data acquisition was proposed for induction motor control, which achieves high performance, up to several Mbps, to meet the data requirement for artificial neural network (ANN) adaptive control. However, it requires an extension module that transfers all acquired data to another computer for storage and processing, which incurs considerable cost and space occupation.…”

“…Storing these vast amounts of data at high speeds during the development and use phase of motor drive systems is a challenging task [17]. Traditional approaches to data storage, such as those using the drive system's own memory device or connecting an external device with highspeed data storage capabilities, have limitations in terms of cost-effectiveness, circuit design efficiency, and space requirements [18], [19], [20].…”

In this study, we propose a real-time data storage method to store the high-frequency motor control data of AC servo motor drives. The Micro Secure Digital Card (MSDC) is chosen as the storage device because of its cost-effectiveness and space efficiency. However, the MSDC has a fatal drawback of lengthy write time, which is solved by applying a double-buffering algorithm and distributing the MSDC writing load based on the multi-core architecture of the microcontroller unit (MCU). The proposed data storage method is implemented using a commercial AC motor drive system with an MCU integrating two digital signal processor (DSP) cores and an MSDC socket. From experimental results, it is demonstrated that the proposed method achieves a remarkable MSDC writing speed of approximately 2.44 Mbps, which is sufficient for realtime storage of critical motor control data at fast 10 kHz motor control cycles. Consequently, the proposed method can be used for motor drive optimizations and applications requiring a vast amount of motor control data storage.INDEX TERMS Real-time data storage, micro SD card, AC servo motor drive, multi-core MCU, doublebuffering algorithm.
