Investigation of cogging forces using reluctance circuits equivalent approximation in a ladder secondary single­sided linear induction motor

New Equivalent Circuits of Single-sided Linear Induction Motor

Recently, single linear induction motor(SLIM), which comes from rotary induction motor(RIM), has been widely applied in transportation systems, especially in intermediate speed arrange, because of its merits, such as ability to exert thrust on the secondary without mechanical contacts, high acceleration or deceleration, less wear of the wheels, smaller turn circle radius and more flexible road ...

Electromagnetic field analysis of novel low cogging force, linear switched reluctance motor, based on 2-D finite element method

This paper deals with electromagnetic design and 2-D (two-dimensional) magnetic field analysis of novel low force ripple linear switched reluctance (LSR) motor. The configuration that has been presented here has a higher number of rotor poles than stator poles, and the purpose of this configuration is to improve the force ripple, which is the weak point of LSRMs. In order to illustrate the ...

Improvement of Electromagnetic Forces in a Single-Phase Induction Motor by Providing a New Winding Distribution

Single-phase induction motors have a wide range of domestic and industrial applications. These motors have a squirrel cage rotor and their stator usually has two windings: main and auxiliary. The use of auxiliary winding in the structure of single-phase induction motors creates two unbalance and asymmetric phases. This causes to increase the spatial harmonics of the field in the air gap, and al...
