Model 9005ASA
9005ASA Automatic Sequential Analyzer is the most comprehensive tester designed to automatically check the quality of 1φ & 3φ wound stators in fast paced production motor shops. The tests are performed in the sequential order with the help of user-defined test times and limits.
The Analyzer accurately detects the faults in the stator and audio/visual alarm indicates the type of fault to the operator. This Analyzer has been widely appreciated by the stator manufacturers in India who have to meet tight deadlines to deliver large number of quality stators to their clients.

  • 1φ & 3φ stators

  • User friendly front panel controls
  • User defined limits and test times
  • Auto/Manual test mode option
  • Dual station jig to eliminate the loading time of stator and also safeguards the operator from high voltages stressed on the stator
  • Proximity switch mounted on the jig to automatically start the test cycle
  • Fast, accurate and completes one test cycle in 12 seconds
  • Audio/Visual alarm indication for the operator

  • A Double Station Test Jig Fixture
  • Housed in dust free enclosure
  • Servo Stabilizer (Optional)
  • In house Air conditioner (Optional)

  • Stator Jig Top Base

    The Automatic Sequential Analyzer performs the tests in the following sequence & in case of a fault; it stops the sequence of tests & sets off a buzzer alarm to the user.
    I) Resistance Test
    The Resistance test detects the variance of resistance values between the phases by applying a constant current to the winding and picking up the potential drop across it.
  • For 1φ windings - Resistance test of Main and Aux winding
  • For 3φ windings - Resistance test of U,V and W winding
  • 10 channel preset limit programmer to set the limits

  •  Three Selectable Resistance Range
     Range1  0-19.99Ω
     Range2  0-199.9Ω
     Range3  0-1999.9Ω
     Display  3½ Digits LED Display
     Test Time  0-10 sec (adjustable)
    II) Rotation Test
    The Rotation detection test is useful in cases of stators. It uses die-cast rotors to check the direction of winding i.e. clockwise or counter-clockwise.

    III) I.R (Megohm) Test
    The IR test checks the strength of the ground wall insulation of the appliance that can be damaged due to dirt, carbon, moisture or weak wire insulation.

     Display  3½ Digits LED Display
     Test Voltage  500V (DC)
     Test Time  0-10 sec
     Limit  0-200 MΩ
    IV) H.V Flash Test
    The H.V Flash test once again checks the strength of the ground wall insulation of the appliance but at a higher applied voltage than the I.R test. If there is sudden surge in the leakage current it indicates that the ground wall insulation is weak and the test has failed.

     Test Voltage  0-2.5KV AC
     Display  3½ Digits LED Display
     Test Time  0-10 sec
     OverTrip Leakage Current
     Leakage Current Limit  0.1-10mA
     Display  3½ Digits LED Display
    V) Surge Comparison Test
    The Automatic Surge test is performed on each phase of the stator to detect the turn-to-turn, coil-to-coil and phase-to-phase insulation and compared with the master stator. If the % variation is over the limit set by the user then the audio/visual alarm is set off to notify the operator about the failure and test sequence is stopped. It can also detect open circuits, grounds, phase reversals, misconnections and wrong turn counts.
    Applied Surge Test Voltage = √2 × (2×E + 1000) where E is the operating voltage
     Max Surge Voltage 5000 Volts
     Max Pulse Current 330 Amps
