摘要： A method of normalizing phase measurements for a motor using a normalizing phase measurements (NPM) algorithm that a processor implements to cause a motor controller coupled to stator terminals of the phases to execute forcing a set of input current or voltage vectors (set of input vectors) including repeating the forcing after rotating the rotor through a full mechanical cycle to generate resulting current or voltage samples (resulting samples) of non-normalized phase A and phase B waveforms. The magnitude of the input vectors are sufficiently small to not move the rotor. A maximum value (x_max) and a minimum value (x_min) are determined for each of the non-normalized phase A and phase B waveforms. An offset value and normalization scale factor (NSF) are determined from the max and min values. The offsets and NSFs are applied to the non-normalized phase waveforms to generate normalized phase A and phase B waveforms.

摘要： Examples include a method for detecting the evolution of the magnetic state of a permanent magnet rotor. The method includes, during a first and a second time interval, applying a respective direct current command signal to the motor to estimate a respective stator resistance value, and applying a respective alternative voltage command signal corresponding to a specific direct axis stator current value to the motor while measuring respective stator phase current values. The method also includes determining respective rotor flux parameters as a function of the measured respective stator phase current values and of the estimated respective stator resistance values. The method further includes comparing the respective rotor flux parameters. The first and second time intervals are separated by a time period which exceeds at least 100 times any one of a first or second interval length.

摘要： A method suitable for characterizing a motor, for instance a permanent magnet synchronous motor, includes obtaining a plurality of winding flux linkage values or terminal voltages of the motor, each corresponding to a different combination of phase current magnitude and phase advance. The resultant flux-linkage values or terminal voltages are transformed into the rotor dq reference frame. The flux linkage model is fitted to the one or more dq-axis flux-linkage values or terminal voltages and their linked phase current magnitude and phase advance using a process of parametric optimisation.

摘要： A motor control device at least includes a speed control part for controlling a motor rotation speed. The motor control device includes a torque correction means for suppressing variation in torque constant due to individual differences of motors. In addition, the motor control device corrects the torque constant by using a correction torque coefficient calculated based on an unloaded speed when a fixed voltage is applied. Alternatively, the torque constant is corrected using the correction torque coefficient calculated based on the motor applied voltage when the motor speed is fixed.
