Product Description
Magtrol’s DUAL TEST 7 is a state-of-the-art motor testing software for PC (Windows® XP sp3/7/8) based data acquisition. Used with a Magtrol Programmable Dynamometer Controller DSP7012, DUAL TEST 7 works on two channels independently with any Magtrol Dynamometer or In-Line Torque Transducer to help determine the performance characteristics of a motors under test. Up to 63 parameters are calculated and displayed utilizing DUAL TEST 7’s feature-rich testing and graphing capabilities.
An integral component of any Magtrol Motor Test System, DUAL TEST 7 performs curve tests in a manner best suited to the overall efficiency of the test rig. Written in LabVIEW™, DUAL TEST 7 has the flexibility to test a variety of motors in a multitude of configurations. The data generated from this user-friendly program can be stored, displayed and printed in tabular or graphical formats, and is easily imported into a spreadsheet.
Magtrol can also make custom modifications to the software to meet additional motor testing requirements.

Applications
DUAL TEST 7—besides being well-suited for simulating loads, cycling the unit under test and motor ramping—is also ideal for production line, due to the full dual channels tests functions. Another time-saving feature, that engineering labs will benefit from, is the ability to duplicate tests and run them automatically. This versatile program is extremely valuable to anyone involved in motor testing.

[post_content] => If currents continuously reach above 20 amps, an external sensor must be used. Magtrol offers three different types of external shunts for use with Magtrol Power Analyzers. The HA Series shunt, designed for power cable hook-up utilizing 3/8-16 screws, has an insulating base and can be mounted on conductive surfaces. The LAB Series shunt also comes with an insulating base, along with thumb screws for the power leads and knurled nuts on the sensing terminals. The FL Series is a relatively small bus, bar-mounted shunt with large end blocks. The comparatively large end blocks and short spacing aid in cooling and allow the shunt to operate in more extreme environments. All shunts are calibrated on equipment with current certifications traceable to N.I.S.T.

[post_content] => The Powder Brake Dynamometer (PB Series) contains, as its name suggests, a magnetic powder. The electrical current passing through the coil generates a magnetic field, which changes the property of the powder, thus producing a smooth braking torque through friction. They are ideal for applications operating in the low to middle speed range or when operating in the middle to high torque range. Like Hysteresis Brakes, Powder Brakes provide full torque at zero speed. Like the Eddy-Current Brake Dynamometers, the PB series are water-cooled, allowing for power ratings up to 48 kW. The PB Dynamometers have accuracy ratings of ± 0.3% to 0.5% full scale (± 2% for PB 2.7), depending on size and system configuration. Additional mounting possibilities include speed pickup and OEM version IS.
Features
- 12 Models with Maximum Torque from 600 mN·m to 1 200 N·m (84 oz·in to 885 lb·ft)
- Braking Power: 150 W to 48 kW
- Stable Braking Torque
- Low Moment of Inertia
- Operation in Either Rotational Direction
- Braking Torque Measurement Integrated
- Integrated Optical Speed Sensor
- Special designs available upon request
Operating Principles
The PB Series - Powder Dynamometers contain, as their name suggests, a magnetic powder. The electrical current passing through the coil generates a magnetic field, which changes the property of the powder, thus producing a smooth braking torque through friction between rotor and stator. The Powder Dynamometers (PB) produce their rated torque at zero speed. The element to be tested can be loaded at standstill to determine the starting torque.
Optical Speed Sensor
Each PB Series Dynamometer has an optical speed sensor delivered as standard. PB 2.7 & PB 43 has an optical speed sensor with a 30-bits pulse wheel; PB 65, PB 115 & PB 15 has an optical speed sensor with a 60-PPR encoder. For higher speed resolution in low speed applications, Magtrol offers a 600-PPR or 6000-PPR encoder as an option.

[post_content] => Magtrol Models 5500 and 5501 are manually-operated switch boxes that permit the connection of up to three Magtrol Dynamometers to a single
DSP7000 Dynamometer Controller. Use of the switch boxes facilitates quick and easy interfacing of multiple dynamometers without the necessity of disconnecting and reconnecting the brake and control cables. For Magtrol
WB Eddy-current or
PB Powder Brake Dynamometers, BOTH a 5500 AND a 5501 Switch Box are necessary. Magtrol
HD or ED Hysteresis Dynamometers only require the 5500.
