Moving toward sensor-less control

Freescale Semiconductor and the Nanjing University of Aeronautics and Astronautics (NUAA)  have jointly developed a space vector modulated – direct torque control (SVM-DTC) solution for industrial motor control applications. The solution is based on an advanced adaptive motor control algorithm featuring low noise and vibration, and does not depend on rotor parameters, simplifying adaptation to a variety of motor types.

Freescale’s MC56F8xxx DSCs integrate high-speed analog functions and efficient 32-bit digital signal processor cores and provide accurate digital control for power supplies and motors. The solution improves the energy efficiency of several types of motors and it reflects a growing trend towards sensor-less control. Freescale and the NUAA started working together in 2005. Joint projects include 180-degree sine wave controlled BLDC motors, PMSM fans, freezers and air conditioning compressors. Contact company for pricing and availability.
