Determining Rotor Position at Both Low and High Speeds
Summary
Researchers at Purdue University have developed an algorithm to estimate the rotor position of a PMSM from zero to high speeds, providing the accuracy of an optical encoder system, but at a substantially lower cost. Furthermore, this technology can utilize advanced control techniques, such as torque ripple mitigation, in the operation of the machine.
