These automated stator testers are used to test AC motors ranging in size from fractional to 5000 hp, as well as DC motors up to about 1500 hp. Manufacturers of motor windings, stators, coils, alternators, and rotors use the Baker WinAST to avoid shipping dead-on-arrival (DOA) motors, or products that prematurely fail or malfunction after being placed in service.
Unlike other volume manufacturing test approaches, this system does not require a master winding to perform routine production tests, nor does an operator need to set test voltages or pass/fail limits when production is switched to another motor model. All test parameters are programmed into a master, “known-good” data file, an operation that can be performed in minutes. When a master file is created, the user is prompted for all necessary information about a given product to be tested, and when complete, the file is permanently stored within the 160 GB of system storage.
Fully automated, full-spectrum quality control testers for motor manufacturers
Built to each customer’s specifications using proven, reliable standard components in a cabinet style rack design
Standard tests include: AC and DC hipot (with micro-arc detection to detect any breakdowns to ground – the only proven method to accurately detect any such faults), surge, inductance, corona and temperature-compensated resistance test capabilities
Rotation-direction test (optional) for testing stators and field coils
Configurable with a range of additional test capabilities
Highly-sensitive computer-controlled testing, analysis and report generation software making testing virtually automatic
Features a Microsoft Windows 7- based application with an intuitive, menu driven user interface
Tests manufacturing processes as well as manufactured products
May be integrated into fully automated lines with automatic fixtures and a PLC (or host computer) communications interface
Designed for many years of rugged industrial use
Recalibration may be done on-site with adjustments to software coefficients via a simple menu (and using ISO procedures)
A high-voltage version of the Baker WinAST – the HV WinAST – is available for conducting tests on low inductance form coils and motor stators of more than 500 kW, or more than 575 V AC.
