摘要： A data processor determines whether a composite torque command Is larger than a preset torque threshold for a time Interval |S302). The composite torque command is convertible into a direct-axis current command and a quadrature-axis current command (S302). The data processor determines whether a rotor speed of the motor is less than a preset speed threshold for the lime interval (S3Q4), The data processor, the current adjustment module, or the current shaping module adjusts the direct-axis current command and the quadrature-axis current command to obtain a revised direct-axis current command and revised quadrature-axis current command for the time interval if the composite torque command Is larger than the preset torque threshold and If the rotor speed is less than the preset speed threshold (S308){ where the revised current commands vary by the detected rotational position of the rotor to achieve a generally constant shaft torque output.

摘要： A control system (120) for a motor (117) includes a current regulation controller (111) for generating a terminal voltage command. The terminal voltage command is used for converting a supply voltage to a three phase voltage to power a motor (117). The control system (120) also includes a terminal voltage command feedback module (108) for controlling the terminal voltage command. The terminal voltage command feedback module (108) compares the terminal voltage command to a determined voltage limit of the supply voltage and generates a d-axis current adjustment command in accordance with the comparison. The d-axis current adjustment command is used for reducing the terminal voltage command below the determined voltage limit. The control system (120) also includes a summer (119) coupled with the terminal voltage command feedback module (108). The summer (119) adds the d-axis current adjustment command to a d-axis current command received from a lookup table (e.g., 109).

摘要： A data storage device stores previous position readings of the rotor for a previous cycle of a pulse width modulation signal applied to the motor (S300). A current raw position reading for the current cycle is received (S302). A predicted position reading for a current cycle is determined based on at least one of the stored previous position readings of the previous cycle (S304). A data processor determines whether a difference between the current raw position reading and the predicted position reading for a first mode and a second mode is within one or more preset thresholds (S306, S307). The data processor selects the current raw position reading as a verified reliable final position reading if a first difference for the first mode is equal to or less than a primary preset threshold or if a second difference for the second mode is equal to or less than a secondary preset threshold (S308).

摘要： A pair of direct d-q-axis voltage commands is associated with a monotonically varying test sequence of test rotor angular positions (S300) to determine a correct rotational direction of a rotor of the motor in response to application of the pair of direct d-q-axis voltage commands to the motor. The rotor of the motor rotates (e.g., self spins in a diagnostic mode) in response to the applied direct d-q-axis voltage commands and applied monotonically varying test sequence of test rotor angular positions (S304). The primary positioning module or data processor determines that conductor connections between the inverter (e.g., motor controller) and the motor are correct if the calculated shaft speed sign is positive with respect to an applied monotonically varying test sequence of rotor angular positions that monotonically increases (S306).

摘要： A sensor detects position data for a rotor of the motor at a first time. A data processor receives the detected position data associated with a first time delay. A sensing circuit senses an analog current at the motor during a second time delay. An analog-to-digital converter converts the analog current to a digital current data during a third time delay. The fourth time delay is detected between actual current reading instant and position reading instant in a data processor. The digital phase current data is transformed into measured direct and quadrature axes control current data based on synchronization or temporal alignment of the position data with the actual measured analog phase current at the starting time by compensating the position data by a sum of the second time delay, the third time delay and the fourth time delay, where the first time delay is subtracted from the sum.

摘要： A data processor establishes a first range of rotational speeds of a rotor of the motor from a first lower limit to a first higher limit (S300 in FIG. 3) and a second range of rotational speeds from a second lower limit to a second higher limit (S302). A hysteresis band or a rotational range of speeds is established such that during operation in the first range the first higher limit is adjusted (e.g., raised by a first amount to be greater than the second lower limit)(S304). A sensor detects or measures a rotational speed of a rotor of the motor (S306). The data processor determines whether the measured rotational speed falls within the first range or the second range, as adjusted by the hysteresis band, to identify a selected speed range (S308). A switching frequency of a pulse-width modulation signal is varied in accordance with the selected speed range (S310).

摘要： A method calibrates a current sensing instant to latch a current value from a set of current signals (402 in FIG. 4). A current command including a magnitude at a Gamma angle is provided to control a motor when the motor is operating in a motoring mode at a shaft speed (404). A matching current command including a same magnitude at a same Gamma angle is provided to control the motor when the motor is operating in a braking mode at a same shaft speed (408). A first actual averaging rms current magnitude of three phase currents of the motor is monitored when the motor is controlled by the current command and operating in the motoring mode (406). A second actual averaging rms current magnitude of the three phase currents of the motor is monitored when the motor is controlled by the matching current command and operating in the braking mode (410). A current sensing instant is adjusted (416) until an observed first actual averaging rms current magnitude in the motoring mode equals an observed second actual averaging rms current magnitude in the braking mode.
