also known as DC tachogenerators, are small DC
generators that output a voltage in proportion to speed. They cannot
indicate position, only speed and direction of rotation. A common mounting style of
analog tachogenerator was the General Electric BC42 and
BC46 Series with
NEMA 56C Foot or
Face mount, and the smaller 5PY
flange mount unit. Analog tachogenerators
can be replaced with modern digital encoders.
Avtron offers a complete
retrofit package using the existing
flange adapter and
coupling already on the motor and a Frequency to Voltage Converter like the
Avtron K661, which resides in the drive cabinet. |
