Moment synchroniczny silnika indukcyjnego o litym i magnetycznie anizotropowym wirniku

The paper deals with problem of synchronous state of work for induction motor with solid rotor. The have been considered different kinds of magnetic anisotropy for the solid rotor. The paper presents analytical solution for synchronous state of work for induction motor. The electromagnetic field distribution is evaluated with the help of separation variable method. The electromagnetic torque is calculated by means of Maxwell stress tensor method, material component and with the help of coenergy function for different rotor magnetic anisotropy cases at synchronous state of work. It has been pointed out that for magnetic rotor may appear electromagnetic torque for certain case of rotor anisotropy
