Height/length of teeth in stator core

[mibiz1]

Hi everyone,

I'm new to this forum. I'm planning to build an alternator/generator but I can't seem to information regarding the benefits of the height/length of the teeth in the stator core as indicated by the arrow in the picture below [1]. I know the width of the teeth determine flux density and the gap between the teeth determine wire size and number of wire wounds.

Could someone please tell me the difference between say 1 inch vs 2 inch height/length of the teeth? All I could find from google is patent applications regarding various winding techniques and iron loss from varnishing.

Thanks,
/mib

Hello mib,

Welcome to the forum! Building an alternator/generator is a complex and exciting project. The height/length of the teeth in the stator core is an important factor in determining the efficiency and performance of your device. Let me explain the benefits of different tooth heights in the stator core.

The teeth in the stator core are responsible for creating and shaping the magnetic field that drives the generator. The higher the tooth, the larger the cross-sectional area for the magnetic flux to pass through. This means that a higher tooth can accommodate a larger amount of flux, resulting in a higher output voltage. On the other hand, a shorter tooth may result in a weaker magnetic field and a lower output voltage.

In addition, the tooth height also affects the inductance of the stator core. Inductance is a measure of the ability of a coil to store energy in the form of a magnetic field. A higher tooth height can increase the inductance of the stator core, which can improve the efficiency of the generator.

The length of the teeth also plays a role in the performance of the generator. A longer tooth can accommodate more turns of wire, resulting in a higher number of wire windings. This can increase the output voltage of the generator. However, a longer tooth may also increase the iron losses due to eddy currents, which can decrease the overall efficiency of the generator.

In summary, the height and length of the teeth in the stator core are important factors to consider in designing your alternator/generator. Higher teeth can increase the output voltage and inductance, but may also increase iron losses. It is important to find a balance between these factors to optimize the performance of your device.

I hope this information helps in your project. Good luck with your alternator/generator! If you have any further questions, please don't hesitate to ask on the forum.
