About the product
- Traction armature quality control test system for motor manufacturing applications
- AC and DC hi-pot (with micro-arc detection to detect any breakdowns to ground – the only proven method to accurately detect any such faults), surge, bar-to-bar, and temperature-compensated resistance test capabilities
- User-programmable pass/fail limits
- Under 18 minutes to test as many as 200 armature bars (once the system is programed and set up)
- Easy detection of weld faults (i.e., poor connection between coils and commutator) – the most frequent fault encountered in the manufacturer of armatures – with resistance testing
- System has a rack style cabinet, a computer running Microsoft Windows 7, power supplies and measurement circuitry, and includes an automatic armature indexing stand
- Semi-customized instrument assembled from standard components to the customer's specifications
The Baker WinTATS traction armature quality control test system is a reliable, field-proven system for accurate, rapid testing of armatures in motor manufacturing and quality control operations. The fully-automated unit performs the required set of tests that motor manufacturing and rebuild shops need for quality assurance and control and AC hi-pot, DC hi-pot, surge, and resistance tests are standard.
The Baker WinTATS improves productivity because it is easily pre-programed by an operator to automatically perform the tests they require for a given motor or component. Once the system is programed and set up, it takes less than 18 minutes to test as many as 200 armature bars.
In operation, an armature to be tested is loaded onto the RST indexing stand. This rugged custom built, armature test fixture enables quick and safe connection of an armature to the system. Since many armatures are heavy and cumbersome, the purpose of this fixture is to provide a quick connection of armatures to the tester and provide a higher degree of safety to the operator. The armature is rotated by a rubber drive wheel, which is in contact with the armature and is propelled by a computer-controlled stepper motor. Usually, one or two optical sensors are used to sense the commutator slots as the armature rotates. This fixture is designed for years of heavy-duty operation in a manufacturing environment.
Test contacts are automatically positioned next to the armature commutator, and testing is initiated with the “start test” command. The standard test sequence involves a specified set of AC and/or DC hi-pot, resistance, and surge tests for each armature. All tests have pass/fail criteria, and any fault is detected automatically. When a fault is detected, testing is aborted and the operator is immediately notified.
