RCbenchmark has announced the release of the production version of its dynamometer for brushless motors. The dynamometer helps designers to optimise motor and gear ratio selection for the perfect balance of torque, power and efficiency for a specific race or frame. The tool measures torque, motor speed, motor efficiency, motor power and motor internal resistance. Motor loading is adjusted by installing different propellers on the inrunner motor with this method of loading the motor was chosen for its smooth and constant load, for the huge load range it provides, as well as for its low cost. The software can export the data to any spreadsheet software, and most tests can be automated with the automatic control feature. The dynamometer was built by designers, for designers, to save time, and to obtain the best performances and it is especially helpful for smaller motors such as used in 1/16th scale vehicles.
