There are four key items that need to be addressed in selecting
the proper motor test system:
- What type of motors are to be tested?
- What is the maximum Torque, Speed and Power of the
motors?
- What motor test parameters do you need to test?
- How do you plan to control the Dynamometer and collect
motor test data?
What type of motors are to be tested?
Magtrol Dynamometers are used for testing virtually all types
of electric, hydraulic and pneumatic motors, as well as internal
combustion gas engines.
What is the maximum Torque, Speed and
Power of the motor under test?
Magtrol Dynamometers are rated in three parameters: Torque,
Speed and Power. How to determine what Dynamometer you need
is discussed in detail here.
What motor test parameters do you need
to test?
Magtrol Dynamometers provide torque and speed data. Using a
Magtrol DSP6001
Dynamometer Controller or Model
6200, mechanical power (in horsepower or watts) is also
computed and displayed. The Magtrol Dynamometer Controller also
contains an analog input which accepts any 0-5 VDC transducer.
The transducer can be used to measure another parameter such
as pressure, air flow, noise or a single temperature point.
If motor electrical input power is to be measured, Magtrol offers
Single and Three-Phase Power
Analyzers. The Power Analyzer option allows for capturing
Volts, Amps, Watts and Power Factor.
A Power Analyzer is a required component
in a test system measuring motor efficiency.
Magtrol also offers multichannel temperature testing hardware
and software. Magtrol can also provide additional parameter
testing via customized data acquisition hardware and software.
How do you plan to control the dynamometer
and collect motor test data?
Magtrol offers both open-loop manual test systems, and PC based
closed-loop test systems.
The open loop system requires motor test data to be acquired
manually. A typical open loop system will consist of a Dynamometer
and a Magtrol 6200 Open Loop Controller. A Magtrol Single or
Three-Phase Power Analyzer can be included as an option. An
open loop system is often used for quick pass/fail testing on
the production line or at incoming inspection. Magtrol's 6200
Dynamometer Controller provides pass/fail testing as a standard
feature.
In a closed-loop motor test system, data is collected on
a PC using Magtrol's M-TEST
Software, a Programmable Dynamometer Controller, and requisite
interface cards and cables. A single or three-phase power
analyzer can be integrated into this system, as well as Magtrol's
Temperature Testing Hardware and Software. Closed-loop systems
are often used in R&D and test lab applications. Closed-loop
systems are also used for production line and inspection purposes,
especially when automatic data collection is required.
