Global warming and drastic weather changes force human beings to rethink how we harvest and consume energy. New ways to increase efficiency in motor applications are critical to ensure the long-term sustainability of the environment. Permanent Magnet Synchronous Motors (PMSM) become more and more popular in air conditioning and refrigeration applications.

PMSM is very similar to Brushless DC (BLDC) motors in terms of mechanical structures. PMSM’s main advantages are high energy density, simple structure, high efficiency, low noise level and high reliability.

Field Oriented Control (FOC) is developed for high-performance applications that are required to operate smoothly over the full speed range, generate full torque at zero speed, and have high dynamic performance including fast acceleration and deceleration. PMSM driven by a FOC-capable controller can deliver precision control without any ripples thus significantly reduce the noise and enhance the efficiency. Myson’s 32-bit MCU, with its strong DSP engine, ADC and PWM, can provide a sensor less approach with current observer for delivering a better FOC. In addition, with this MCU, Myson is able to provide a highly integrated solution with a comprehensive protection mechanism including voltage, temperature, current and the motor protections.

Myson is committed to provide the FOC solution for PMSM control. We provide a high level of integration and abstraction with user-friendly and easy-to-use GUI for fast development and system performance monitoring. Myson’s solution is your best choice for developing systems with PMSM as your target motor.
