Fairchild's BLDC / PMSM motor controller with parallel processing core provides a simple conversion for AC motor control design. Development tools and a configurable motor control library minimize design resources and achieve faster time to market.
Motor control application designers are currently switching from traditional general-purpose or AC motor designs to more mature brushless DC (BLDC) motors or permanent magnet synchronous motor (PMSM) designs. However, if the designer cannot effectively obtain advanced and complex motor control algorithms, no matter which method is selected, it is challenging. This may result in huge R & D resource expenditure and longer design time.
To help designers cope with these costs and software burdens, Fairchild Semiconductor has developed the FCM8531 analog and digital integrated motor controller. FCM8531 is a customized configurable solution with user guides, reference designs, and evaluation boards that help motor control designers shorten time to market and minimize software design work.
Parallel processor in single-chip design
FCM8531 is a three-phase hybrid BLDC / PMSM controller with two parallel processors-an advanced motor controller (AMC) and an embedded microcontroller (MCU). This product provides a complete single-chip solution for complex motor control applications. The two core processors work independently, but cooperate to exchange data through internal communication interfaces that help avoid system hangs and enhance hardware protection. FCM8531 minimizes software burden through its integrated hardware controller and MCU interface management function, and realizes more efficient and fast load response motor system.
Customized design for simplified functions
AMC can be applied to various motor designs, using Fairchild Semiconductor Library that can be configured and stored to execute powerful algorithms such as sine wave control, field-oriented control (FOC) and direct quadrature (DQ) control} to provide high-performance motors control function. The MCU interface paired with AMC allows users to easily change the value of the register to meet the requirements of different motor operation processes and characteristics. This device is ideal for solving start-up jitter in speed sensorless fan applications, as well as noise and inefficiencies in various fan and pump applications. FCM8531 has multiple hardware protection functions, such as overvoltage protection and overcurrent protection. Its design considers and provides quick response to all failure modes, while the embedded MCU can easily implement additional functions.
Easy-to-use development tools
Fairchild Semiconductor's Motor Control Development System (MCDS) consists of an integrated development environment (IDE) and an MCDS programming tool that allows engineers to configure AMC and develop code for the MCU. Together with the processing core, the system provides an integrated software engineering platform, which is conducive to the rapid development of motor control programs. MCDS-IDE is easy to use and completes the design target schedule. When used with the MCDS programming tool suite, code programming can be completed quickly, allowing real-time adjustment of the motor running signal.

Industrial Energy Storage System
The main function of the Industrial Energy Storage System is to store energy in the industrial field to meet the energy demand in the industrial production process. It is an energy storage solution for improving energy efficiency and power supply stability in industrial production systems.
Main effect:
Energy peak shaving: Industrial energy storage systems can store energy and release energy at the peak of energy demand to meet the high energy consumption demand in the industrial production process. This helps to achieve a balanced deployment of energy and avoid energy waste or power outages caused by imbalances in energy supply and demand.
Reserve power supply: When the power supply of the power grid is unstable or there is a power outage, the industrial energy storage system can be used as a backup power supply to continue to supply the power required by industrial equipment and ensure the continuous operation of industrial production.
Energy saving and emission reduction: Through rational use of energy storage, industrial energy storage systems can optimize energy consumption and reduce energy waste, thereby achieving the goal of energy saving and emission reduction, and reducing the impact of industrial production on the environment.
Differences from other energy storage systems:
Scale and capacity: Industrial energy storage systems usually have large scale and energy storage capacity to meet the high energy demand in industrial production. Home energy storage systems, on the other hand, are usually smaller and are mainly used in home photovoltaic power generation systems.
Application scenarios: Industrial energy storage systems are mainly used in the industrial field to meet the energy demand in the industrial production process. The Home Energy Storage System is used in the home photovoltaic power generation system to improve the energy self-sufficiency of the home.
Control and management: Due to the large scale of industrial energy storage systems, their control and management require more complex and precise technical means to achieve efficient energy utilization and stable supply. Home energy storage systems are usually relatively simple and easier to automate and manage.
Generally speaking, the main function of industrial energy storage systems is to meet the energy demand in the process of industrial production, realize the balanced deployment of energy, and the stability of the power supply. Compared with home energy storage systems, it is different in terms of scale, capacity, application scenarios, and technical complexity. The application of industrial energy storage systems helps to improve the energy utilization efficiency of industrial production, optimize energy management, and promote sustainable development and green production.
