Problems solved by technology

The chips provided by these semiconductor manufacturers can be used not only in the field of motor control, but also in various fields such as household appliances, electric meters, and LED control. Due to the wide range of application fields, the internal resources of the chip are too rich, and the cost of the chip increases.
Moreover, the chips provided by these semiconductor manufacturers are not specifically optimized for motor control applications, which is inconvenient for users to use.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a microcontroller for field-oriented vector control of a motor. Background technique [0002] In recent years, permanent magnet synchronous motors (PMSM) and brushless DC motors (BLDC) have been widely used in various fields such as industrial systems, electric vehicles, drones, air conditioners, and fans. Control chips mainly include DSP, FPGA, MCU, and ASIC. Because the MCU chip has the advantages of software programmable, easy development, flexible control, and low cost, it is widely used in the control system of PMSM and BLDC. According to survey data, the global market for motor control MCU chips reached US$10 billion in 2013, and is expected to grow at a rate of 10% in the next two years. According to different application fields, BLDC control schemes based on MCU chips include square wave control schemes and field-oriented (FOC) algorithm control schemes. Different...
