A low-cost sensorless technique for load torque estimation in a hybrid stepping motor
UNSPECIFIED. (1999) A low-cost sensorless technique for load torque estimation in a hybrid stepping motor. IEEE TRANSACTIONS ON INDUSTRIAL ELECTRONICS, 46 (4). pp. 833-841. ISSN 0278-0046Full text not available from this repository.
This paper presents a method of torque measurement in a hybrid stepping motor without the use of speed or position sensors. It is shown that torque ripple can be minimized by appropriate shaping of the phase-current pulses and that efficiency can be maximized when the level of mechanical load applied to the shaft is known. A controller is described which generates a signal related to the mechanical load by observation of the phase-current profile using a novel low-complexity technique. Practical results are presented, showing the torque estimation relative to measured torque.
