Along with the continuous development of shipbuilding technology, also increasingly high to the fail safe of boats and ships operation.When the emergency of marine main engine disorderly closedown; Hope is used axle generator as motor; Drive screw with it and rotate, the assurance boats and ships can promptly navigate by water gets back to the harbour, calls this operational mode of AC rotor generator " TAKE ME HOME " pattern usually.Make AC rotor generator realize this function; Just must solve the starting problem of AC rotor generator when moving as motor; Present most of boats and ships all use no-brush synchronous generator as AC rotor generator; In motor when operation, can't across-the-line starting, thereby can't realize the reversible operation of generator, motor.
Summary of the invention
The invention provides a kind of band master of a system motor that can be used as the asynchronous motor use and solved the problem of the generator of boats and ships axle band system as asynchronous motor use and direct startup.
The present invention overcomes the above problems through following scheme:
A kind of axle band master of system motor that can be used as the asynchronous motor use; Comprise electric machine stand and motor driving shaft; On electric machine stand, be respectively arranged with connection box for motor and field power supply; In electric machine stand, be respectively arranged with Stator Windings of AC Motor and exciter stator winding; On motor driving shaft, be disposed with AC motor rotor winding, rotating rectifier, axle sleeve and slip ring from left to right; Axle sleeve is provided with the exciter rotor winding, and slip ring is the slip ring that is provided with two conducting rings, and the support above the slip ring is provided with the short-circuited brush device; The lead wire of three phase windings of Stator Windings of AC Motor is connected with the binding post in the terminal box; The lead-out wire short circuit of two phase windings in three phase windings of AC motor rotor winding together, the shorted end of the lead-out wire of two phase windings in three phase windings of AC motor rotor winding is drawn the electricity ring with the negative terminal of rotating rectifier and slip ring one respectively and is connected, the lead-out wire of another phase winding in three phase windings of AC motor rotor winding is connected with the anode of rotating rectifier and another conducting ring of slip ring respectively.
During relay power on being arranged on the short-circuited brush device, the short circuit sheet in the described short-circuited brush device links together through two carbon brush being fixedly connected with it and two conducting rings of slip ring; When the relay on being arranged on the short-circuited brush device cut off the power supply, the short circuit sheet in the described short-circuited brush device and two carbon brush that are fixedly connected with it were unsettled above slip ring, and two conducting rings that promptly are provided with in the slip ring are not by short circuit.
The present invention has realized the convenient conversion of boats and ships axle with synchronous generator, synchronous motor and three kinds of modes of asynchronous motor of main motor, has solved the direct startup problem as asynchronous motor, has practiced thrift the energy and has reduced the cost of integral device.
