T5401WAC Tachsyn Transducer

Model T5401WAC Tachsyn Transducer from ServoTek Products, part of the Tachsyn tach/commutator family, are unique transducers that can be used as brushless dc tachometers or brushless dc motors. They provide a true tachometer signal and full-time analog commutation control. A miniature remote mounted circuit board (CT-4) provides as field excitation for the transducer as well as the required conditioning for the output signal.

  • Linear, low noise tach signal down to zero speed
  • High accuracy commutation as 6-step Hall-equivalent outputs
  • Elevated temperature operation up to 155 degree Celsius
  • Low inertia, passive rotor for high speeds and rapid acceleration
