BSi High Speed Spin Test
    
BSi provides the world's manufacturers of high speed machinery everything from medical centrifuges to jet engines, with the reliable, precisely controlled shaft power to put their own equipment to the test. In addition, BSi engineers, designs, and manufactures test facilities built around these drive systems.

Test Rigs
Barbour Stockwell, inc. engineers draw on vast experience to provide reliable drives and test rigs for testing rotating components under the most extreme conditions. We have provided test rigs with speeds up to 250,000 rpm. Test specimen temperatures have ranged from cryogenic to 1100 degrees Celsius.

Drive Systems
The ability of Barbour Stockwell, Inc's drive systems to provide ultra-high rotational speeds with precise speed control is the company's key advantage in powering spin tests or driving the components in other test rigs. Whether an air turbine or electric motor drive, tests are conducted under the precise control of our TC3 controller with the test programming convenience provided by our SPIN3 software.
The air turbine system is generally a less costly investment than the electric motor; particularly if an air system already exists. However, the electric drive will be more economical to operate since there are fewer energy conversions required in driving and the energy stored in the rotor at speed can be returned to the mains when braking. Nonetheless, each system has its place depending on the application requirements and economics.

Test Rigs


While Barbour Stockwell, Inc is best known for its spin test facilities, the company also designs and builds all kinds of rigs for testing the components of high speed machinery. As in our spin pits, BSi's unsurpassed ability to generate and precisely control extraordinarily high speeds is the key competitive advantage.
BSi engineers also draw on our vast experience to provide reliable drives and rigs to meet the most demanding requirements under the most extreme conditions. We have engineered and manufactured rigs for testing bearings at speeds to 250,000 rpm. We have delivered test benches for testing abradable seals at temperatures to 1100 deg. C.
A prestigious university laboratory recently took delivery of a BSi rig for testing the ability of coatings to mitigate erosion due to liquid jet impingement at speeds to 500 meters per second. Speed control, even while the rotor blades are being subjected to water droplets at 20,000 rpm, is better than +/- 5 rpm.
 

 
BSI Drive Systems

Air (and Steam) Turbines

In addition to the Tangential Turbines historically supplied for spin testing, BSi has developed a line of Radial Inflow Turbines for meeting the demands of applications requiring very high power at very high speeds.

TANGENTIAL

- Extraordinary robust - well suited to the rigors of spin testing
- Can be bidirectional
- Bidirectional configuration yields very effective brking
- Low specific speed machine - good performance only at relatively low power levels.
RIT
- Higher efficiency
- High performance at high power levels, e.g.: 
- 130 HP at 130,000 RPM
- 800 KW at 50,000 RPM
The Radial Inflow Turbines are generally designed specifically for each application. Standard models exist, on the other hand, for the company's Tangential Turbines. They are categorized by the diameter of the turbine rotor disk. Standard models exist for spin test service and for driving other rigs.

Electric Drive Systems

BSi Electric Motor High Speed Drive systems employ High Speed, High Efficiency Motors with sophisticated Direct Torque Control Drives. When required, speed is increased with the BSi engineered gearing. Spot on speed control is assured by virtue of our TC3 controller working with the motor drive.
BSi electric drive systems meet all CE Standards and Norms. Moreover, they reduce utility demand charges and introduce less harmonic distortion in the power supply than conventional DC drives.

AC MOTORS
- Highest efficiency - over 90% at base speed
- Develop full power at 50% rated speed
- Precise speed control
- Direct torque control drives
- Proprietary TC3 controller with proprietary speed control algorithms
GEARBOXES DESIGNED AND BUILT BY BSi
- Dual ratio - maximum torque for the large, low speed test articles
- Helical for quiet operation and long gear life
- Double helical - eliminates thrust loads to extend bearing life
 
BSI  Spin Test Services
  

F.A.S.T. incorporates:
- A TC-3 drive controller with unparalleled speed control
- A custom designed and programmed computer system, providing equipment control and data acquisition functions
- Cyclic spin tests that operate completely unmanned, 24 hours per day
- Monitoring of all critical test parameters with automatic response to any occurrence during a spin test
- Maximized safety for your personnel and your equipment

The BSi system allows remote access for monitoring and even control through the use of modems. This allows personnel to track a critical test's progress around the clock. If a test is interrupted, data is recorded for analysis. If it is determined that a test can continue, the test can be restarted from the remote location. Final test data is supplied to you in printed reports or on a CD.

Additional BSi Services
- Engineering services for arbor design (structural and dynamic analysis)
- Balancing for rotors up to 270 kg (600 lbm) and 660 mm (26 inches) in diameter
- Still photographs of burst tests, or
- Ultra high speed digital video photography of the event
