Speed synchronization control method for multi motor drive system of belt conveyor

open access: yesGong-kuang zidonghua, 2023
In the production process of a multi motor drive system of belt conveyor, if individual motor speeds are not synchronized, it can cause conveyor belt breakage and mechanical and electrical equipment damage.

Impact of cross-saturation in sensorless control of transverse-laminated synchronous reluctance motors [PDF]

open access: yes, 2006
Synchronous reluctance (SyR) motors are well suited to a zero-speed sensorless control, because of their inherently salient behavior. However, the cross-saturation effect can lead to large errors on the position estimate, which is based on the ...

Cross-Saturation Effects in IPM Motors and Related Impact on Sensorless Control [PDF]

open access: yes, 2006
Permanent-magnet-assisted synchronous reluctance motors are well suited to zero-speed sensorless control because of their inherently salient behavior. However, the cross-saturation effect can lead to large errors on the position estimate, which is based ...

Torque prediction using the flux-MMF diagram in AC, DC, and reluctance motors [PDF]

open access: yes, 1996
This paper uses the flux-MMF diagram to compare and contrast the torque production mechanism in seven common types of electric motor. The flux-MMF diagram is a generalized version of the flux-linkage versus current (ψ-i) diagram for switched-reluctance ...

Recognition of Acoustic Signals of Synchronous Motors with the Use of MoFS and Selected Classifiers

open access: yesMeasurement Science Review, 2015
This paper proposes an approach based on acoustic signals for detecting faults appearing in synchronous motors. Acoustic signals of a machine were used for fault detection. These faults contained: broken coils and shorted stator coils.

Comprehensive Comparative Study on Permanent-Magnet-Assisted Synchronous Reluctance Motors and Other Types of Motor

open access: yesApplied Sciences, 2023
At present, the induction motor (IM), synchronous reluctance motor (SynRM), ferrite-assisted synchronous reluctance motor (ferrite-assisted SynRM) and interior permanent magnet motor (IPM) are research hotspots, but comprehensive comparative research on ...

End effects in linear tubular motors and compensated position sensorless control based on pulsating voltage injection [PDF]

open access: yes, 2011
The sensorless position control of permanent-magnet (PM) synchronous motors can be successfully implemented by superimposing a high-frequency voltage signal on the control voltage.
