Avnet's motor control solutions are the first step to reducing energy consumption

When exploring energy-saving and consumption-reduction strategies for air conditioning systems, the performance and efficiency of motors, the core components that drive fans, compressors, and other modules, undoubtedly play a crucial role in overall energy consumption. Avnet's motor control solutions, through precise control algorithms, enable air conditioners to achieve high levels of energy efficiency.

The core of this solution lies in the STM32G0 MCU and the STIPNS1M50T-H Intelligent Power Module (IPM). The STM32G0 MCU is based on the high-performance ARM® ^Cortex® -M0 ⁺ 32-bit RISC core and operates at frequencies up to 64MHz. The STM32G0 MCU integrates a 12-bit analog-to-digital converter and a 16-bit high-performance timer with complementary PWM outputs and programmable dead-time insertion, enabling more precise and efficient motor control. Avnet's motor control solution is driven by sinusoidal current and utilizes a sensorless Field Oriented Control (FOC) algorithm and single-resistor current sensing technology, delivering low noise and peak efficiency at a relatively low cost.

In addition to the high-performance MCU, another key feature of Avnet's motor control solution is the STIPNS1M50T-H low-power intelligent power module (IPM). This IPM integrates a three-phase MOSFET inverter bridge, an operational amplifier, and an NTC thermistor for temperature control. This highly integrated design not only simplifies circuit design but also improves system reliability and stability. Furthermore, the IPM's low power loss further reduces system energy consumption, contributing significantly to energy conservation and consumption reduction.

Leveraging the exceptional performance of both software and hardware, this solution not only supports stall detection and motor rotor vibration detection, improving controller reliability, but also supports headwind-resistant startup. In adverse headwind conditions, it intelligently adjusts the motor startup strategy to ensure smooth startup and stable operation of the air conditioner.

Thanks to these excellent features, Avnet's motor drive solutions are not limited to traditional air-conditioning fan systems, but can also be widely used in various environments such as indoor and outdoor industrial and household fans . While bringing coolness to people, they also encourage energy conservation, emission reduction, and green environmental protection in various industries.

To intelligently inspire life with technology, Avnet will continue to take action to improve people's living environment and provide diversified solutions for smart living.
