Features :
- Compact and Light Weight and can substitute a range of
imported / indigenous tachos
- High Linearity
- Low Ripple
High Stability and Extreme Reliability
in Hostile Industrial Environments
PRINCIPLE
OF OPERATION :
The DC Tachogenerator is a speed transducer,
which develops DC voltage proportional to speed of the motor
connected to it.
Permanent Magnetic field eliminates the need of external excitation
and offers extremely reliable and stable outputs. The accuracy
of the tachogenerator decides the maximum accuracy of speed
of the controlled machine.
FEATURES
:
The tachogenerator incorporates
following features to ensure reliable and long service in
most hostile environments.
- Silver graphite brushes to ensure long life, minimum voltage
drops, and spark free commutation.
- Prelubricated and sealed precision ball bearing used for
long maintenance free operation.
- Brush holders and brushes designed to ensure smooth movements,
equal brush tension and spark free operation.
- Electrolytic grade copper segments molded and machined
to close tolerances in commutator for sparkless commutation
and minimum wear. Use of mica insulation between segments
to offer maximum dielectric strength and stability.
- Armature built with special silicon steel stampings and
wound with polyester grade class ‘F’ enameled
wire and impregnated for high electrical and strength.
- Armature dynamically balanced for vibration free rotation,
sparkless commutation and low ripple content.
- Totally enclosed construction to offer protection from
hostile industrial environments.
- Easy accessibility of brushes and commutator for maintenance.
- Powder coated / Stowing Paint for good finish, corrosion
free outer body.
OPTIONS
:
- Any deviation in electrical and mechanical details from
our standard models.
- Temperature compensation.
- Foot mounting, terminal box, and flexible couplings.
- Hollow shaft versions available.
