Abstract | Real-time thermal management of electrical machines relies on sufficiently accurate indicators of internal temperature.One indicator of temperature in a permanent-magnet synchronous motor is the stator winding resistance. This study applies twocurrent injection techniques to a commercially produced permanent-magnet servomotor, which are applicable under load andcause minimal disturbance to the shaft torque. The current injection techniques applied here enable the temporary boosting ofresistive voltage and consequent application to low-resistance, high-voltage machines. The effectiveness of the approach isdemonstrated by tracking the change in winding temperature during a 2 h load cycle. |
