Product Specification

Tachogenerator

 
Tachogenerator is a device which generates an electrical output directly proportional to the shaft speed. The voltage thus generated is fed to a speedometer for speed measurement and/or used as feed - back signal for controlling the speed of a rotating machine / equipment. In every automatic control system, since the system performance is directly related to the performance it becomes essential that the

Tachogenerator must satisfy certain minimum requirements such as:
Linear The rectified output voltage should be strictly linear with respect to the rotational speed
Output signal The ripple content in the rectified output signal must be as low as possible
Temperature effect Variations in ambient temperature should have negligible effect on the TG output
Long-term stability Instability of output cause due to aging of parts, shift in magnetic circuits etc., should be minimum.
Unique features of Tachogenerator
  • ALINCO permanent magnet in the rotor assembly gives long term stable operation under varying ambient temperature.
  • Large number of poles (48) results in a high frequency output and hence good dynamic response, linearity and wide speed control, along with low ripple content in the rectified output.
  • Rotor and stator assemblies are encapsulated with epoxy resin to prevent any ingress of moistures, dust etc.
  • Stator assembly is housed in cast iron body to minimize magnetic interaction and consequent losses.
  • Grease filled, double shielded ball bearings are used for maintenance free operation.
  • Two mounting options-foot mounted and flange mounted.
  • Speedometer can be calibrated to suit the customer's requirements.
  • Compact and rugged construction provides longer life with excellent performance even under severe environments.
  • If required, TG can be supplied with rectifier unit, for DC operations.
