Study on Performances of Amorphous Three-Phase Asynchronous Motor

Abstract

The motor of traditional silicon material possesses the disadvantages of high iron loss, power consumption and a low efficiency. A new type of motor iron core made of amorphous alloy material is put forward in this paper. First, in order to research the stator characteristics of amorphous iron core and silicon steel core, the stator core of three-phase asynchronous motor is fabricated with silicon and amorphous materials. The magnetic performances and alternating loss of the iron cores made by two kinds of materials are tested with in the TD8120 test system. Then, the finite element analysis model of three-phase asynchronous motor is established. The motor of amorphous iron core and silicon steel core are simulated by finite element method. It is showed that the simulation and test results are in good condition within error range. It can be known that the performance and efficiency of motor made by amorphous alloy core are better than the performance and efficiency of motor made by silicon steel core. Results presented in this paper have important significance to carry out the study of amorphous motor.
