UK motor company installs instrument-grade torque sensors
The team wanted a relatively small torque sensor that could fit into their existing dynamometers to ensure the electric motor operate at optimal efficiency,” claimed Datum.
Chosen was the M425 sensor, which has a wide-enough operation range to remove the need to switch the torque transducer for different size motors, and outputs torque, power, and rotational speeds in real time.
The instrument grade sensor offers up to 24 bit resolution and can operate over 1-4,000 sample/s. RPM measurement is base on 30pulse/revolution.
