Abstract
The paper deals with a special type of reluctance motor called Anisotropic rotor reluctance motor. As the name implies, advantage is taken of the internal anisotropy of the rotor magnetic structure. Axially laminated grain oriented silicon steel is used in the rotor. This unconventional configuration of assembly of rotor laminations results in a high ratio of direct axis to quadrature axis reluctance. Compared to the conventional reluctance motor, pull out torque of more than three times and a power factor as high as in an induction motor is obtained. Several motors of ratings up to 60 HP. were built and tested.
The superiority of these over the conventional or the commercially available "Synduction Motor" is established both theoritically and by test results. Combined with the ease of manufacturing almost akin to the squirrel cage induction motor, a high power factor and pull-out and pull-in performance, the Anisotropic motor poses a serious challenge to the brushless synchronous motor for constant speed applications.
In industrial applications, like textile mill applications and computer power supplies where reliable power drives are required, this new type of Anisotropic motor is expected to find greater demand in the future.
