Abstract:
1. An alternating current (AC) three-phase induction motor comprising: extension shafts respectively to two ends of base elements of the three-phase induction motor, wherein said extension shafts respectively include components of balancing eccentric washers, balancing eccentric block, outer shell, O-ring, bolts, washers, and sleeve bearings; wherein respective extension shafts on two ends of the AC three phase induction motor are embedded with a predetermined number of said balancing eccentric washers, and wherein a balancing eccentric block is configured on each of said respective extension shafts at an inner most layer of said balancing eccentric washers, between the eccentric block and said sleeve bearing, and said O-ring is located between an inner most layer of said balancing eccentric washers and said balancing eccentric block; said AC three-phase induction motor, controlled by a frequency changer, is capable of producing a number of frequencies for generation different amplitudes, and each frequency is capable of generating higher load and lower load, wherein different amplitudes serve to control force for said balancing eccentric block and said balancing eccentric washers spin to achieve a predetermined goal of generating varied speeds and loads; wherein, for an alternative arrangement of two AC three-phase induction motors, two of said AC three-phase induction motors can be serially connected with a cable.
