Design
The test bench is designed with a 2PB115 Powder Dynamometer
mounted horizontally and a TMB 212 In-Line Torque Transducer
mounted vertically. They are connected by a right-angle
1:1 gearbox that transmits the power while changing
the angle of the load. The torque transducer is used
to directly measure the torque and speed value at the
motor output.
Motor Fixturing
The fixing of the motor in the test rig is designed
to fit directly on the motor output gear for quick and
easy use. The connection and motor fixture are flexible
enough to allow easy adaptation to different sized motors
to be produced in the future.
Customized Software
Magtrol's MT-TEST software is adapted to control the
customer's power supply, monitor the temperature, acquire
and save test data, and provide a test certificate for
each tested motor.
Testing
The motor under test can be loaded from 0 to 200 N·m,
in a speed range of 0 to 500 rpm. The acquired data
includes input voltage, input current, torque, speed
and temperature parameters. The input and output power
is calculated, providing the user with motor efficiency
values. Each test setup can be recorded and the measured
data of each tested unit is saved with its serial number.
