The application discloses a kind of test simulation equipment for simulating throwing anchor, dragging anchor in ship movement.The equipment includes water tank and track system, tow control system, anchor operating mechanism and data acquisition and processing system;Water tank and track system provide test water environment and the height of trailer (for simulating ship) from water surface, tow control system drives trailer to move along track, anchor operating mechanism controls anchor dropping position by receiving signal, realizes throwing anchor simulation, data acquisition and processing system monitors anchor chain stress in real time, captures anchor body into water and dragging process by high-speed camera, all data are integrated transmission to control computer by synchronizer, and after processing, output anchor dropping speed curve, anchor chain dragging force peak value and drag anchor trajectory and other parameters.The all test simulation elements of the application are controllable and known, easy to use, can play the role of improving the accuracy and test efficiency of ship throwing anchor, dragging anchor test simulation.

The application discloses a stator and a motor of an even-layer flat wire motor with a number of slots per pole per phase of 2, comprising a stator body and a stator winding; the stator is provided with six stator slots per pole, and two stator slots per phase per pole, the motor has a pole pair number p, p is an integer greater than or equal to 1, and each stator slot contains 2n layers; each phase winding contains a plurality of parallel branches, and the parallel branches are composed of an even number of winding units in series; the number of winding units of a single parallel branch * the number of parallel branches = 4p; the winding units are sequentially connected by first-layer positions and n kinds of cross-layer hairpins to the 2nth layer of the stator slot, each kind of cross-layer hairpin contains one, and the span of the same parallel branch between the adjacent two winding units in the same layer welding section of the first layer and the 2nth layer is 5 and 7, or 7 and 5. Based on the above structure, firstly, the induced electromotive force harmonic is weakened; secondly, the power line end and the center line end are concentrated, the busbar volume is small, the structure is simple, the end space is reduced, and the manufacturing cost can be reduced.
