“…In the last decades, several driving methods in the PMSM drives with Hall sensors have been proposed in the literature [1], [2], [13]- [17]. The techniques in [1] and [2] have used the discrete absolute position of ±30 • resolution detected by a combination of three Hall signals at only start-up operation.…”

“…Recently, some approaches to compensate the misalignment effect of Hall sensors have been introduced in [15]- [17]. The method in [15] has presented an automated process that can obtain the actual Hall state transition points in which an iterative routine determines the offset between ideal and actual points, and the resultant actual state transition values are stored in a lookup table during only initial commissioning.…”

This paper presents an improved approach for estimating high-resolution rotor position in permanent-magnet synchronous motor (PMSM) drives with low-resolution Hall-effect sensors. A vector-tracking position observer in conjunction with discrete Hall sensors' output signals has been proposed, which is similar to a phase-locked loop structure. It consists of a position error detector, based on the vector cross product of the unit back-electromotive-force vectors obtained from a stator electrical model, and a proportional-integral-typed controller to make the position error rapidly converge to zero. This structure does not only compensate the misalignment effect of Hall sensors but also enhance their transient operating capability. The effectiveness of the proposed approach has been verified from several experiments in a low-voltage PMSM drive for automotive applications.Index Terms-Hall-effect sensors, high-resolution position estimation, permanent-magnet synchronous motor (PMSM), vectortracking observer.

“…The rotor position of PMSMs is typically measured using speed/position sensors, e.g. encoders, resolvers… [28]- [31], while the magnet polarity is commonly measured using digital hall-effect sensors [22]- [26]. Consequently, commercial PMSMs are frequently equipped with both types of sensors [28]- [31].…”

Abstract-Knowledge of the permanent magnet (PM) temperature in PM synchronous machines (PMSMs) is of great importance both for control and monitoring purposes. Increase in PM temperature during motor operation can degrade the magnetic flux strength and consequently the machine's torque production capability, also can cause irreversible demagnetization of the PM. Direct measurement of the PM temperature is not viable in practice, due to both cost and reliability issues. Indirect PM temperature estimation methods recently studied can require knowledge of thermal or electrical model parameters or can have undesired effects on motor operation. In this paper, the feasibility of using low cost halleffect sensors for PM temperature estimation is investigated. Hall sensors are present for detecting the initial position of the rotor in majority of PMSM applications for which incremental encoders are used for control. The proposed method can therefore be implemented with low or no additional cost. Experimental results on two IPMSMs show that the method is capable of providing non-invasive estimation of the PM temperature without a priori motor parameter information for monitoring and protection against excessive increase in temperature. 1 Abstract-Demagnetization, Hall-effect sensor, Permanent magnet, PM synchronous motor, Thermal monitoring.

“…An observer based algorithm is proposed in [36] to eliminate periodic torque disturbances. In [35] the disturbance rejection properties of a vector-tracking observer for the BLDC machines is evaluated but the drive is equipped with low resolution hall-effect sensors. In [37], [38] an analytical approach in frequency as well as time domain are used in order to investigate the dynamic properties of AC permanent magnet synchronous machines for both sensor based and self-sensing techniques.…”

This paper presents a load torque estimation method for self-sensing brushless DC drives. Torque ripples in brushless DC machines can be reduced using load torque information. This method uses the terminal voltage, the virtual neutral point voltage and the DC-bus current of the machine. The algorithm uses the variation of successive back-EMF samples to estimate the rotor speed. The rotor position is estimated by defining an intermediate function of estimated speed and back-EMF samples. An estimate of acceleration is used to estimate load torque. The load torque information is used for increasing the dynamic stiffness of the drive. The mathematical background is given and discussed and the simulations as well as the experimental results prove the performance of the proposed method.Index Terms-Permanent-magnet brushless DC-machine (BLDC machine), back-EMF zero-crossing, self-sensing control, estimation method 0093-9994 (c)
