Cogging torque and torque ripple reduction of modular permanent magnet machines

2016 XXII International Conference on Electrical Machines (ICEM), 2016
In order to minimize the cogging torque and torque ripple for surface mounted permanent magnet (SPM) machines, this paper proposes a C-core modular stator which can be obtained by inserting flux gaps (FGs) into every stator tooth. The electromagnetic performances of C-core modular PM machines such as open-circuit flux linkage, phase back-EMF, cogging ...

Torque ripple minimization in direct torque control of induction machines

38th IAS Annual Meeting on Conference Record of the Industry Applications Conference, 2003., 2004
A duty ratio control scheme for inverter-fed induction machines using the direct torque control (DTC) method is presented. An improved steady state torque response was achieved using the duty ratio control and had shown less torque ripple compared to the conventional DTC.

Autonomous torque ripple compensation of DD motor by torque observer

Proceedings 1993 Asia-Pacific Workshop on Advances in Motion Control, 2002
From a standpoint of effective torque transmission, the direct drive motor (DDM) is advantageous over conventional AC servomotors because it does not require a reduction gear. The paper presents autonomous torque ripple compensation of the DDM with a permanent magnet rotor by using a software-implemented torque observer.

Transverse-flux motor for enhanced torque and reduction of torque ripple

2015 17th European Conference on Power Electronics and Applications (EPE'15 ECCE-Europe), 2015
Windings are significant factors affecting the manufacturing cost and reliability of motors. For use in electric vehicles, motors should be highly efficient, inexpensive, and highly reliable; moreover, high efficiency and reliability are major requirements for wind generators.

Embedded Joint Torque Sensor with Reduced Torque Ripple of Harmonic Drive

2013
Joint torque sensors are widely used in service robots for force control and collision detection. However, since torque sensors are often directly connected to a harmonic drive, it must be insensitive to torque ripple, the noise from the harmonic drive due to its unique structure.
