Cmsemicon CMS32M5526S024 Motor MCU Chip Solution for OA Printers

Against the global trend of energy conservation and consumption reduction, energy efficiency optimization for OA printers is crucial. Motor power consumption accounts for 60%–70% of the total energy use of the equipment, so optimizing motor control and reducing power consumption has become the key to improving overall equipment performance.

DC motors are widely used in OA printers due to their flexible speed regulation, energy efficiency and high performance, among which motor drive and control technology is essential to realizing their advantages. Cmsemicon has launched a dedicated OA printer solution based on the CMS32M5526S024 main controller, balancing energy efficiency and reliability to provide an efficient path for office equipment upgrading.

Supported by a high-performance main controller and optimized algorithms, the core performance features of this solution are precisely tailored to the requirements of OA printers, ensuring stable and efficient equipment operation.

The solution adopts dual-resistor FOC control technology, eliminating the need for complex timing control and current reconstruction. It delivers stable and accurate sampling, effectively avoids non-observable areas, balances control accuracy and cost, improves motor operating efficiency, and shortens the development cycle.

High speed accuracy is a core highlight of the solution. Powered by an ARM Cortex-M0 core with a maximum clock frequency of 64 MHz, the CMS32M5526S024, together with optimized algorithms, enables precise motor speed control, preventing blurred printing, paper jams and other issues, thus ensuring print quality and operational efficiency.

The solution features low vibration and low noise. By optimizing the drive control strategy to suppress torque ripple, it extends the service life of motors and printers, meeting the quiet requirements of office environments.

It is equipped with a comprehensive built-in protection mechanism that monitors abnormal conditions in real time, including overvoltage, undervoltage, overcurrent, phase loss and locked rotor. It triggers protection promptly to avoid equipment damage, improving solution reliability and reducing maintenance costs.

The solution adopts the CMS32M5526S024 + PNMOS combination. The CMS32M5526S024 features rich peripherals (32KB Flash ROM, 8KB SRAM, etc.), low power consumption, high reliability, and an operating voltage range of 2.1V–5.5V. Paired with PNMOS, it further optimizes drive efficiency, reduces energy consumption, and achieves a balance between performance and cost.

The application block diagram is centered on the CMS32M5526S024, integrating PNMOS drive, current sampling, protection and interface modules. The main controller outputs drive signals to control motor operation, with all modules working in coordination to ensure smooth implementation of printing, paper feeding and other functions.

This solution effectively solves the pain points of traditional OA printers such as high energy consumption, insufficient accuracy and poor stability. Backed by Cmsemicon’s technological expertise, it delivers both energy efficiency and reliability, helping enterprises reduce costs and providing users with a superior printing experience.

In the future, Cmsemicon will continue to focus on the field of motor drive and control, optimize solution performance, and launch more products tailored to industry needs, supporting the green upgrading of office equipment.
