5 Preparing for data collection

5.1 Mounting the Hall sensor
The Hall sensor shall be glued to a stator tooth.
It is important to make sure that the sensor is not mounted over a cooling duct since this affects the
measurement. Do not glue the Hall sensor over a section joint if your stators is divided into sections. It
is better to use the adjacent stator tooth.
The cables from the sensors can either be routed through a cooling duct to the back of the generator or
up along the inside of the stator before it is connected to the KROM instrument.
Figure 5. The Hall sensor is 15.2 x 27.2 millimetres and
fits well on most stator teeth between two cooling ducts.
