ONE. Principles of automotive tachometer:
Aircore Tachometer&Pointer style tachometer has a wide range of applications at all kinds of automobiles&Car&Motorcycle speed instructions Instrumentation. It is usually from the Aircore meter and drive circuit composition. Aircore meter is usually by two vertical intersection of the line package and with the pointer of magnet table core composition. Magnet's magnetic field distribution for the radial, it consists of ND-Fe-B permanent magnetic materials made of some. Generally use the injection-moulded ND-Fe-B magnets. Two-line package around the system at a fixed frame. Two winding package at qualcomm on current that will produce a magnetic field, and its synthesis of magnetic field angle will change these two lines of the current packet size, thus a corresponding change in in the two-line package generated magnetic field strength, that is changing the angle convenience for produce a rotating magnetic field. In this way, when the rotating magnetic field up to a certain extent, will be able to make permanent magnet made of sheet magnet core to produce rotation, so that the fixed table in the magnet core of the pointer to produce rotation, finally through the dial plate to indicate the corresponding scale.
TWO. Features of Tachometer Injection-Moulded NdFeB Magnets:
-Automobile odometer magnet use of injection-moulded magnetic NdFeB as materials, mode of bipolar magnetizing, magnetic field strength at 850GS ~ 2500GS are selected can be adjusted.
-Once Injection Molding with shaft and inserts with high dimensional precision,so as to avoid dimensional deviation,product cracks,product fragmentation and other disadvantage during secondary assembly
-Unique polymer-coated magnet technology and good anti-corrosion effect, magnetic properties of a higher consistency.
THREE. Part of tachometer NdFeB magnet specifications:
Size(mm) D12*3-------Axis Size(mm) D1.4*24 ------- surface magnetic (Gs) According to customer product needs
Size(mm) D12*3-------Axis Size(mm) D1.4*21.5------- surface magnetic (Gs) According to customer product needs
