Abstract
The utility model discloses a generator rotor punching sheet, which is provided with a punching sheet body with round outer contour. The two winding slots are symmetrically arranged on the round edge of the punching sheet body. A partition is arranged at the central axis of the winding slots to separate the winding slots into a left chamber and a right chamber. The generator rotor punching sheet is characterized in that the separation is solid, and the width of the partition is 1/8 to 1/10 of the sum of the maximal width of the left chamber and the right chamber. The generator rotor punching sheet has the beneficial effects of increasing the width of the winding slot wall and rotor punching sheet pole body, reducing the magnetic flux density on the silicon steel sheet, allowing the magnetic lines of force on the silicon steel sheet to pass smoothly, reducing the heating value of the rotor punching sheet, reducing the reactive power consumption of a generator, and improving the output efficiency of the generator.

The shortcoming of existing generator amature punching is: it is too much that the winding slot of being opened in the punching body takies in the punching body live part, make the narrowed width of winding slot cell wall and rotor punching main body pole body on the punching body, promptly reduced the rotor pole-core width, magnetic flux density when producing same magnetic field on the silicon steel sheet increases, rotor punching heating and copper loss are bigger, increase the idle energy consumption of generator, reduced the delivery efficiency of motor.
The utility model content
Problem at the prior art existence, the purpose of this utility model is to provide a kind of generator amature punching, can increase the width of winding slot cell wall and rotor punching main body on the punching body, promptly increase the rotor pole-core width, magnetic flux density when producing same magnetic field on the silicon steel sheet reduces, rotor punching heating and copper loss reduce, and reduce the idle energy consumption of generator, improve the delivery efficiency of generator.
For achieving the above object, the technical solution of the utility model is as follows: a kind of generator amature punching, be provided with outline and be circular punching body, the round edge symmetry of this punching body has two winding slots, the place is provided with partition in described winding slot axis, this partition is divided into left and right two chambers with described winding slot, and its key is: described partition is solid partition, this partition width be described left and right two chamber Breadth Maximums and 1/8～1/10.
Cut off width and significantly reduce, increased the space size of two chambers of winding slot effectively, also provide the space of widening for winding slot cell wall and rotor punching main body pole body.The pole body effective area of silicon steel sheet strengthens, and can reduce the magnetic flux density on the silicon steel sheet, reduces the caloric value of rotor punching, reduces the idle energy consumption of generator, improves the delivery efficiency of motor.
Described winding slot cell wall is the circular arc limit, and the body width a at described winding slot cell wall root place is 5～8 times of the body width b of place, cell wall top.
Cell wall is the circular arc limit, is easy to smoothly passing through of the magnetic line of force on the silicon steel sheet, reduces the magnetic resistance of the magnetic line of force on rotor punching.
Described winding slot cell wall top inwardly is provided with bending, and the both sides, top of described partition are respectively arranged with bending towards described winding slot notch, and described bending and the bending at grade, spacing to coil windings and gland in the described left and right chamber.
Increase to cut off height, make and cut off consistently, gland is risen to the bending part of winding slot notch, also increased the winding space of winding slot with described winding slot cell wall height.
The top of described partition has the welding breach, and the aperture of this welding breach is 100 °～150 °, and the bottom of this welding breach is provided with semicircle bonding pad.Can be by bonding pad so that the stack of a plurality of rotor punching is welded to form rotor.
Beneficial effect: a kind of generator amature punching is provided, can increase the width of its winding slot cell wall and rotor punching main body pole body, reduce the magnetic flux density on the silicon steel sheet, and the magnetic power on the silicon steel sheet is smoothly passed through, reduced the caloric value of rotor punching, reduce the idle energy consumption of generator, improve the delivery efficiency of motor.
