Keterangan
The brakes a motor and determines the brake power
Parameters as torque, speed, current, voltage, frequency, cos , etc., can be analized.
(FRE-FE) braking system (electronic brake/ prony/ magnetic powder It involves applying on the same axle of the motor that is going to be tested, another
motor with higher power, braked by a speed variator, where we introduce the wished
speed. Both motors are connected to the power supply and the power absorbed by the
test motor is measured at each speed by a wattmeter.
With the torque indication at the digital display we get the torque motor, deducing the
torque/speed, torque/power and speed/power curves.
