System and method for motor control through improved location measurement

A motor control determines if a motor is rotating at steady state velocity and then populates a table with information about each individual motor sector. At steady state velocity, the duration of the motor within an electrical sector is measured. The duration of the complete mechanical rotation of...

Zusammenfassung:A motor control determines if a motor is rotating at steady state velocity and then populates a table with information about each individual motor sector. At steady state velocity, the duration of the motor within an electrical sector is measured. The duration of the complete mechanical rotation of the motor is determined. The controller determines a ratio of the measured duration of the sector to a duration of a complete mechanical rotation of the motor. The ratio of sector duration to rotation duration is stored in a table. The controller is configured for controlling the motor using the table values.
