As we all know, the motor control system is the key to ensure efficient operation and low power consumption, but now it is required to minimize energy consumption and loss, and to continuously improve the flexibility and robustness of the machine operation, so as to meet the demanding application equipment. . So for designers, not only is the development cycle shortened, but also faces various innovation challenges.
To this end, Dabit will hold the 12th (Hangzhou) Motor Drive and Control Technology Seminar in Hangzhou on May 30, 2019. Through technical exchanges and seminars, it is beneficial for enterprises to clearly define the direction of research and development and improve their deficiencies, and quickly occupy and enhance the high-end market share.
Recently, Toshiba has developed a variable frequency drive solution for brushless DC motors. Its solutions can be widely used in kitchen products, such as range hoods, to enable the range hood to achieve strong suction, large air volume and large static pressure.
This reference design uses Toshiba motor drive dedicated microcontroller TMPM375FSDMG and intelligent power module (IPD) TPD4123AK for motor control. This solution uses a vector control algorithm to achieve non-inductive variable frequency motor control. The MCU with Arm® Cortex®-M3 core is combined with Toshiba's unique vector engine for precise control of the range hood. The hardware structure is simple and reliable, and the software uses vector engine to realize vector operation, high speed and reliable, and simple program structure.
On the application side, the STMicroelectronics STSPIN motor drive embeds all the required functions for efficient and high-precision drive, ensuring that every advanced motion profiler is in operation, not only reduces the host microcontroller but also ensures flexibility. With reliability.
Moreover, with supply power as low as 1.8 volts, the STSPIN motor driver enables motor-powered smart devices to save a significant amount of power.
