| Popis: | Efficiency and power loss are the necessary metrics for evaluating the performance of electrical drives. These two metrics are calculated based on the measured input and output power of the drive. Input power is calculated from the measured terminal voltages and currents, whereas output power is calculated by multiplying the measured motor speed with the measured shaft torque. Torque transducers are normally used to measure the windup shaft torque. This method is effective for steady-state speed operation. This paper proposes an observer structure that uses standard dynamometer sensors that are capable of estimating the shaft torque during both steady-state and transient speed operations. This enables the motor losses to be measured during transient speed operations (acceleration/deceleration), which is generally not feasible using standard torque sensors. |
