6.6
Speed and position sensor (MiniCoder)
Example of design: toothed wheel
The MiniCoder scans a target wheel (toothed wheel) made from ferromag-
netic material. The magnetic field of the built-in encoder is modulated by the
moving target wheel.
q
The sensor detects the change in magnetic field and converts this into a si-
nusoidal output signal.

ESD protection
ESD protection is provided by creating an electrically conductive connection
between the rotating shaft of the HF spindle and the motor housing.
q
