Abstract
The preferred embodiment the invention proposes pertains to a three-phase induction motor, and operates on the premises of having the extension cords on two ends of the motor embedded with several balancing eccentric washers and a balancing eccentric block added, of which the eccentric block contains a sleeve bearing, and one end of the eccentric block is fitted with a bolt, with the bolt head covered with rubber; o-ring is fitted between the balancing eccentric washer and balancing eccentric block, whereby using the invention's frequency changer for controlling an AC 3-phase induction motor serves to generate multiple frequencies for generating different amplitudes, which can be use to control the speed and load emitted between the eccentric block and balancing eccentric washer.
Claims5
An AC three-phase induction motor, of which the AC three-phase induction motor's extension shafts to two ends of the base elements are comprised of the components of the balancing eccentric washers, balancing eccentric block, outer shell, O-ring, bolts, washers, sleeve bearing;
- of which,
- The extension shafts on two ends of the AC three-phase induction motor are embedded with a number of balancing eccentric washers, and a balancing eccentric block is configured on the shaft of the most inner layer's balancing eccentric washers;
- between the eccentric block and shaft contains sleeve bearing, and between the most inner layer's balancing eccentric washers and balancing eccentric block contains O-ring;
- The 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 the balancing eccentric block and balancing eccentric washers spin off to achieve the goal of generating varied speeds and loads. As an alternative, two similar AC three-phase induction motors can be serially connected with a cable.
