Application
Magtrol has developed a customized test system dedicated
to the automatic testing of small DC motors ranging from
7 to 75 W. |
 |
| Components |
- 2 HD Hysteresis Dynamometers,
DSP6001 High-Speed Programmable Dynamometer Controller
- 6510e Single-Phase Power Analyzer
- MT-TEST 4.0 Motor Testing Software with Temperature
Testing
- Temperature Measuring Module: able to monitor up
to 8 thermocouples
- DC Power Supply (1.5 kW)
- Custom Motor Fixture
- Laptop Computer
|
Custom
Table
All of the components mentioned above are mounted on a
versatile table. The stand is designed from lightweight
aluminum with casters for smooth mobility, and is sturdy
enough to support up to 3 Magtrol dynamometers. It is
equipped with a built-in cabinet and locking drawer-ideal
for a laptop computer-as well as an open shelf which can
accommodate a printer or be used for other storage. The
connection between the motor and the power supply, as
well as the connection of the thermocouples, are made
by fast clamping connections incorporated on the table
surface.

Custom
Motor Fixture
The motor fixture is integrated with the dynamometer in
the form of a sliding platform, allowing easy adjustment
of the axial position of the motor to the dynamometer.
X and Y positioning is made using precision screws having
a resolution of 50 micrometers. The non-magnetic motor
support allows fast clamping of the motor in the test
position. |
Testing
This small DC motor CMTS conducts
the following tests: |
- With the motor being supplied by a constant DC voltage,
an increasing breaking torque is applied from free
run to lock rotor
- Characterization of starting torque
- Dynamic testing of the motor with repeated test
cycles and data acquisition of measured parameters
(torque, speed, input current, input voltage, temperature,
input/output power, power factor and time)
