1. SKF Static Motor Analyzer Baker AWA IV Introduction Baker AWA IV static motor analyzers are the go to instruments for motor repair reliability and maintenance professionals who need to understand the electrical condition of motors their organizations depend upon Weak motor insulation often degrades to the point of causing prema ture and unexpected motor failure which in turn can result in costly unplanned downtime of production machinery The Baker AWA IV is a fully automated motor analyzer that automatically performs repeatable user programmable tests to thoroughly assess the strength of a motor s insulation and circuit It 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 instrument with an intuitive touch screen user interface It delivers accurate repeat able 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 main tenance professionals the information they need to minimize costs and unplanned downtime Improve test reliability The Baker AWA IV is a Windows based Instrument that can be programmed to per form a specific set of tests on a given motor Unique user programmed attributes ca2. 50 60 Hz at 2 5A Baker AWA IV 4 Oto 4000 V 450 A 094 OMS 2 5 to 200 us Div 250 500 1 000 2 000 BZ adi Oto 4 000 V 5 000 uA 0 1 1 10 100 pA Div 1 10 100 1 000 pA 215 w10 gt 50 000 MQ 0 001 to 100 Q 8 2 kg 18 Ib SoA e203 6203 15x 8x8 85 to 264 VAC 50 60 Hz at 2 5A 1 Note surge voltage accuracy meets and is based upon the Z540 standard at four times measurement uncertainty calibrated within three percent Baker AWA IV 2 Oto 2000 V 250 A 02 0 1 uF 2 5 to 200 us Div 250 500 1 000 Biz ag Ms Oto 2000 V 10 000 uA 0 1 1 10 100 pA Div 1 10 100 1 000 pA 215 10 gt 50 000 MQ 0 001 to 100 Q 8 2 kg 18 Ib Sre E AO Oks 15x8x8 85 to 264 VAC 50 60 Hz at 2 5A What s tn the box e Power cord e USB flash drive with desktop software e User manual on USB flash drive e Test leads e Keyboard with integrated mouse Optional accessories Baker PP24 Baker PP30 Baker PP85 Baker ZTX low impedance test accessory USB plug and play printer USB wireless network adapter SKF USA Inc Electric Motor Condition Monitoring 4812 McMurry Avenue Fort Collins CO 80525 USA Tel 1 970 282 1200 1 800 752 8272 SKF is a registered trademark of the SKF Group SKF Group 2014 The contents of this publication are the copyright of the publisher and may not be reproduced even extracts unless prior written permis sion Is granted Eve
