Motor control refers to the control of starting, accelerating, running, decelerating and stopping the motor. A resistor is added in series between the power supply and the motor, and the current is controlled by increasing the resistance value, which can control the motor speed.
· The logic of the new energy truck is inseparable from the motor control. In each subsystem, a separate system is required to support it; any complex circuit is composed of some basic simple circuits.
· Simple understanding, the motor controller is Like the human nerve center, each subsystem is the nerve endings, and the motor controller is used to summarize instructions .
However, the motor drive control in the chip field has unlimited prospects, and major manufacturers have begun to insist on implementing independent controllable technologies. ON Semiconductor has recently focused on the expansion of SiC production capacity and launched the latest MOSFET products, especially motor control and DC-DC conversion, which have developed rapidly. The "little red man" silicon carbide field in the semiconductor industry has been extremely competitive recently. The power solutions integrating intelligent motor controllers and high-efficiency SiC FETs and power solutions integrating intelligent motor controllers and high-efficiency SiC FETs launched this year are very hot.
Qorvo launched a power solution integrating intelligent motor controllers and high-efficiency SiC FETs in February this year, and soon launched a new generation of 1200V SiC FET series in May.
Qorvo's motor controllers are often used in new energy vehicles.
The main uses of high-voltage wiring harnesses include motor controller cables, power battery high-voltage cables, fast charging wiring harnesses, slow charging wiring harnesses, and high-voltage accessory wiring harnesses.
In addition, related studies have shown that: the strong chain project of the auto parts industry can promote the development of drive motors , motor controllers, charging piles and other fields; automotive SiC MOSFET products that have passed the tests of car companies and manufacturers can be applied to new energy vehicle motor control Inverters, high-power charging modules, photovoltaic inverters and high-power energy storage and other fields.
· Nowadays, the product lines of a large number of manufacturers include motor control, signal chain, lithium battery protection, power management and other fields.
· Many MCU companies and joint R&D centers will give full play to the advantages of both sides in terms of motor control, battery management system (BMS) MCU chip design, algorithm development, etc., and carry out in-depth cooperation.
The cooperation projects will focus on automotive-grade embedded motors Research and develop products such as control chips, automotive-grade environmental sensor chips, and isolated drive chips with functional safety to accelerate the transformation of scientific and technological achievements.
