Sensorless motor control applications rely on a motor model. This motor model requires knowledge of certain motor parameters in order to have an accurate representation of the motor. This model is then used to run an estimator, which will then provide the unknown variables such as rotor flux angle or speed. A problem occurs when the motor parameters are unknown, incorrect, or if the parameters change over time. Typically a well-defined motor is used for an end application, but in some cases, the motor has not been defined or there are several motors used during the product’s life. InstaSPIN identifies motor parameters and tracks them in real time. Although identifying the motor is not a must for all applications, it provides an easy and better out of the box experience to run any given motor sensorlessly. Other algorithms in the marketplace require an intensive tuning process upfront, even before running the motor in closed loop. The result of this process is the identified motor parameters and automatically tuned current loops.
