Best Customer Service Is Our Strong Point

DC Tachogenerators give you accurate DC Voltage output proportional to speed of its mover. They are widely used in applications for feedback and display purposes.

Specifications:	Standard Options (EXTRA) :
• Current: Up to 200 mA • Speeds: Up to 10000 rpm • Voltages: 4V to 200 V / 1000 rpm	• Temperature Compensation • Terminal Box / Connector • Foot Mounting • Extended Shaft

Standard 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. 1. Silver graphite brushes to ensure long life, minimum voltage drops, and spark free commutation. 2. Prelubricated and sealed precision ball bearing used for long maintenance free operation. 3. Brush holders and brushes designed to ensure smooth movements, equal brush tension and spark free operation. 4. 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. 5. Armature built with special silicon steel stampings and wound with polyester grade class ‘F’ enameled wire and impregnated for high electrical and strength. 6. Armature dynamically balanced for vibration free rotation, sparkless commutation and low ripple content. 7. Totally enclosed construction to offer protection from hostile industrial environments. 8. Easy accessibility of brushes and commutator for maintenance. 9. Powder coated / Stowing Paint for good finish, corrosion free outer body.

OPTIONS : 1. Any deviation in electrical and mechanical details from our standard models. 2. Temperature compensation. 3. Foot mounting, terminal box, and flexible couplings. 4. Hollow shaft versions available.
