The Baker AWA-IV automatically performs repeatable, user-programmable tests to thoroughly assess the strength of a motor’s insulation and circuit. In fact, it is the only high-voltage test instrument that a user can program to perform a specific set of insulation tests prior to being in the field, and then use as programmed in the field. The AWA-IV is also used to assure quality of motor rebuilds or new production motors before they are placed into service.

The Baker AWA-IV is a simple-to-use test instrument with an intuitive, touch-screen user interface. It delivers accurate, repeatable results regardless of the skill level of a given operator. It easily detects problems that low-voltage testers cannot find by performing a comprehensive set of both high- and low-voltage tests.

Results are presented in simple, easy-to-understand graphs and reports that give motor maintenance professionals the information they need to minimize costs and unplanned downtime. The ability to apply identical tests to a given motor over a long period allows trends to be analysed, revealing the degradation of insulation over the motor’s lifetime. This allows maintenance professionals to predict when a motor may fail, and plan its replacement accordingly.

韩漫app歪歪漫画免费下载The AWA-IV offers computer control and waveform monitoring advantages over equivalent manually controlled instruments. The analyser’s embedded computer conducts the tests, stores the results and continuously monitors voltage levels while testing. If the analyser detects a weakness in the insulation during a given test, the test is interrupted, the operator is alerted and all test parameters at the time of the interruption are reported.

The AWA-IV’s benefits can be extended to low-impedance coils, such as armatures, through the use of the Baker ZTX low impedance coil accessory. The ZTX, which includes the ATF5000 commutator probe accessory, allows the AWA-IV to apply surge tests to coils which require higher currents.

韩漫app歪歪漫画免费下载In an industrial setting, the consequential cost of failure or unplanned downtime of critical rotating machinery can be significant. The Baker DX series can apply a wide set of off-line electrical tests to assess the condition of motors and coils.

韩漫app歪歪漫画免费下载In a motor repair shop, or for new production motors, the Baker DX gives confidence that a motor is correctly wound and insulated, before it’s deployed in the field.

The standards-compliant surge test – a signature feature of Baker testers for decades – is the only test that can safely expose turn-to-turn insulation weaknesses. The Baker DX can find early indications of insulation weakness and faults in windings, between phases, coil-to-coil and in groundwall insulation. It can identify if contamination is impacting insulation strength. It can also detect problems with connections such as feed cable insulation weakness, motor imbalances, opens or high resistance.

韩漫app歪歪漫画免费下载The DX’s benefits can be extended to low-impedance coils, such as armatures, through the use of the Baker ZTX low impedance coil accessory. The ZTX, which includes the ATF5000 commutator probe accessory, allows the DX to apply surge tests to coils which require higher currents.

Baker Surveyor DX Software
韩漫app歪歪漫画免费下载 Surveyor DX software enables Baker DX operators to use a personal computer to store more test data, generate and view reports across the full spectrum of  Baker DX tests, and share and compare analysis with other maintenance personnel using data from multiple analyzers.

B) Dynamic electric motor analysers

STATIC MOTOR ANALYSER

  • Monitors and assesses conditions across a running “machine system” that impact the health and performance of the motor within the system
  • Evaluates the quality of incoming power fed to motor
  • Assesses motor performance indicators
  • Tracks the amount and condition of load placed on the motor
  • Instrument connection options: at a motor junction box, at the instrumentation cabinet, inside a motor control cabinet (MCC), from outside an MCC (requires a Baker EP1000 (dynamic motor link))
  • Designed for rugged site use in tight spaces typical of industrial environments
  • AC or battery operation
  • Visual confirmation of motor integrity
  • Facilitates survey of plant-wide motor efficiency
  • Microsoft Windows 7 operating system

The Baker EXP4000 is a powerful tool, designed for site use, to analyse the motor running under its normal load. It tracks multiple data types to identify trends that indicate potential problems. Voltage and current are measured and a series of parameters are then calculated, including power quality, rotor bar condition, % load, % operating efficiency, average torque value, torque ripple showing variation within process, monitoring of start-up transients (volts, current and torque), and much more.
韩漫app歪歪漫画免费下载 The EXP4000 enables root-cause analysis, starting with separation of mechanical and electrical issues that may be present in a motor-machine system. By monitoring many different parameters and using advanced software algorithms, the EXP4000 is designed to pinpoint challenges across the system, including those with the power supplied, variable-frequency drive, the motor, and the load placed on the motor. Examples of the wide range of problems it may detect include:

  • wrong settings on a supply transformer’s taps, poorly distributed single-phase loads, overloading (saturating) supply transformers, excessive VFDs on low voltage busses, excessive non-harmonic frequencies on a VFD, missing line-inductors on VFD applications and missing or open power factor correction capacitors
  • thermal overloading of the motor
  • current related problems
  • broken rotor bars, mechanical issues, transient overloading, mechanical imbalances along with bearing problems and load issues such as cavitation

The Baker EP1000 Dynamic Motor Link is an optional accessory which is installed permanently inside the motor control cabinet (MCC), and which provides a low-voltage connection port on the cabinet’s door. A technician can simply connect the EXP4000 to that port without the need to open the cabinet or power down the motor. This provides obvious safety benefits, as well as improved convenience and productivity where a large number of motors need to be monitored.

韩漫app歪歪漫画免费下载Through use of the Baker EXP4000, along with a static motor analyser, such as the Baker AWA-IV, maintenance professionals have the means to minimize unexpected failures while maximizing uptime of motors and the machinery that they drive.

  • 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.

韩漫app歪歪漫画免费下载Megger Baker Instruments designs and manufactures electric motor test systems for original equipment manufacturers (OEMs) that help ensure their motors and coils meet or exceed the quality expectations OEMs wish to set with their customers. The Baker WinAST and Baker HV WinAST are semi-custom, fully automated, high-volume electric motor testing units that can test thousands of motors, generators or coils per day, depending upon the size and types of motors, or the testing fixtures used.

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.

韩漫app歪歪漫画免费下载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.

TRACTION ARMATURE TESTING SYSTEM

  • Traction armature quality control test system for motor manufacturing applications
  • 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, 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 programmed 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 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. AC hipot, DC hipot, surge and resistance tests are standard.

In operation, an armature to be tested is loaded onto the armature indexing stand. This ruggedized, 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.
