New Lexseco 2060 Core Testers bumps our automated core testing capacity to 2500 horsepower.
Core Testing saves you tens of thousands of dollars in undetected wasted electricity costs. It catches damage to internal motor parts that you would never see as well as proves that repairs were successful.
A motor in need of rewinding should be core tested both before and after rewinding preventing you from throwing away money on electricity wasted in a bad core. Computerized Core Testers with ample capacity make these tests both accurate and very fast. Without a large core tester, these tests are rarely done due to the labor hours and material costs to manually calculate & perform them. And smaller cheaper core testers can't do the job on large motors. Just having a small tester isn't enough - large core testers are expensive. It's important to know the size capacity of the core tester.
A motor with a bad core could easily cost you many times the purchase price of the motor in wasted electricity each year!
New Laser Alignment Systems have been added to our many other CSI based systems. These new tools allow us to align motors and driven equipment with only about 1/8 of a turn of the shafts (only need a 40 degree partial revolution). This saves tremendous time when trying to align large equipment, gearboxes, or equipment impossible to make a full revolution on. Faster alignment times allows Reed to be a low cost solution.
The software provides quality assurance reports showing such details as starting and ending alignments as well as system vibration levels.
Reed has added a D165 tester to it's arsenal of QA equipment. This unit can apply 15,000 volts & 800 amps for testing of larger motors. It's also useful for more accurate bar-to-bar testing Traction Motor type armatures.
Additionally, the software can be used to test and run electrical trending programs on customer's sites to prevent unplanned losses of large motors.
A Surge Test supplies high voltages to the phases of a 3 phase motor and then overlays the resulting sine-wave pictures of each phase on top of each other. Defects such as winding shorts can be spotted if the sine-wave overlays show separation between any of the phases.
A DC Hi-Potential test inputs high-voltages into the winding and then measures leakage to ground. Contaminated windings, wet windings, defects in ground-wall insulation can all be detected and corrected before these conditions cause an emergency situation.
These same tests are used to document Quality Control of incoming and outgoing motor repairs at the Reed Plants.
Trick or Treat! You have shopped around for the lowest priced motor ... and now you have cost yourself thousands or tens of thousands of dollars.
WHY? Simple; ELECTRICITY costs.
Take a 100 Hp / 1800 motor: It costs you about $500-$600 more to buy a Premium Efficient Motor over a Standard Efficient Motor. Lower Priced Standard Efficient Motor (94.5% Eff) uses $82,984 in electricity per year. Higher Priced Premium Efficient Motor (95.8% Eff.) uses $81,858 in electricity per year. Each year you spend $1,126 MORE in electricity using the lower price standard efficient motor.
Trick or Treat - in the first year, by buying the cheaper priced motor, you just cost yourself $500 to $600 in extra electricity! Now multiply $1126 in extra yearly electricity cost by 10 years average motor life ...
to save $500 up-front on the motor price, you just cost yourself at least $10,000 over the next 10 years. Yikes!
FOCUS on the 800 pound gorilla in the room - the cost of electricity - not the chicken feed price differences of the motor. 50Hp / 1800 RPM motor uses about $42,000 in electricity each year 200Hp / 1800 RPM motor uses over a $160,000 in electricity each year
It's the efficiency rating that matters - not the initial purchase price.
Click on the "New Motors" page on the left for a link to an energy calculator that will get down to your specific motor choices, cost of electricity, hours of usage. Its just downright crazy not to do this quickie homework - thousand of dollars are at stake!
If your company decides who repairs their equipment by sending out a lot of bids and merely picks the cheapest price .... you may want to watch this video... it could be a real eye-opener.... the truth is out there! (click photo to right to watch movie)

We bet your plant has numerous instances of this problem costing you big $ waste as you read this - MISALIGNMENT !
Correct alignment is not easy... it takes some pretty sharp technicians with experience using dial indicators or expensive laser alignment equipment and the right tolerances to get the right alignment. Here are a couple quickie questions that your alignment people need to be able to answer:
If they align with dial indicators; what is the importance of "sag" and how do you calculate it?
If the motor and driven equipment change temperature under operating load, is this an important factor? should anything be done after initial alignment?
Should the coupling manufacturer's tolerance specification be used to determine the proper alignment tolerance for the motor and driven equipment?

Or call Reed's Field Service group to provide you with Laser Alignment service.
Or just follow the old "Ah... it's aligned good enough".... we'd surely appreciate the machine work and bearing job ;>}
