Twin-armature rotary-linear induction motor

IEE Proceedings B: Electric Power Applications, 1983
The twin-armature, rotary-linear induction motor is one of several types of motors with two degrees of mechanical freedom. Its rotor can perform either separately or simultaneously linear and rotary motions. In the paper, the performance characteristics of the rotary-linear induction motor are presented.

Investigation of a rotary-linear switched reluctance motor

The XIX International Conference on Electrical Machines - ICEM 2010, 2010
A novel direct-drive rotary-linear switched reluctance motor (RLSRM) is proposed. The motor has the advantages of robust mechanical structure, low manufacture cost and capability of operation under hostile environments. Simulation tools such as finite element analysis (FEA) are applied for the verification of motor performance and corresponding ...

Design and Control of a Decoupled Rotary-Linear Switched Reluctance Motor

IEEE Transactions on Energy Conversion, 2018
A decoupled two-degree of freedom in the linear and rotary directions of a motor based on switched reluctance principle is investigated. First, the structure of the motor is introduced, and the design procedure for the main parameters of the motor is elaborated. Also, the magnetic decoupled structure for the motor is illustrated.

Circuit modeling of double-armature rotary-linear induction motor

IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014
An equivalent circuit model of a double-armature rotary-linear induction motor is proposed. The stator of the motor possesses rotary and linear-tubular armatures placed aside one another. Both armatures interact with a cylindrical double layer solid rotor which can move rotary, linearly or with helical motion.

Rotary-Linear Switched Reluctance Motor: Analytical and Finite-Element Modeling

IEEE Transactions on Magnetics, 2019
Rotary-linear switched reluctance motors (RLSRMs) have been introduced to realize simultaneous rotary and linear motions in one structure. This paper proposes the modeling of RLSRM in two manners: analytical and finite-element methods. In the first approach, a model is proposed based on position-wise functions which describe the governing equations of ...

Design and Analysis of a High Acceleration Rotary-Linear Voice Coil Motor

IEEE Transactions on Magnetics, 2017
To meet the high requirements of precision machining, electrical machines with high acceleration and high precision have become a dedicated field of research. A rotary-linear voice coil motor (VCM) is proposed here, which features the advantage of a high acceleration and a two-degree-of-freedom motion.

Design and 3D-FEM analysis of a rotary - linear Switched Reluctance Motor

2016 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM), 2016
A new structure for a rotary - linear Switched Reluctance Motor (RL-SRM) is presented in this paper. It has been mainly designed to engage and disengage a rotating gear. The motor is comprised of a three-phase 6/4 rotary SRM and a two-phase transverse flux linear SRM.

Analysis and Optimization on Armature Reaction of a Rotary-Linear Voice Coil Motor

2019 22nd International Conference on Electrical Machines and Systems (ICEMS), 2019
The paper concerns the analysis and optimization on armature reaction of a rotary-linear voice coil motor(VCM), aiming at the application for multi-degree-of-freedom complex movement platforms. The distributions of the magnetic field in the air gap are studied firstly, under both of no-load and load conditions.

Modeling dynamic end effects in rotary armature of rotary-linear induction motor

2013 International Electric Machines & Drives Conference, 2013
The performance of twin-armature rotary-linear induction motor is presented in this paper. The stator consists of a rotary armature and linear armature placed aside one another. Both armatures have a common rotor which consists of solid iron cylinder covered with a thin copper layer. The rotor can move rotary, linearly or with helical motion.
