CUSTOMER CARE COMMITMENT

When electrical power fails, it's no small matter. Repairs must be made as quickly as possible. That's where United/Richter Electric Motors excels. Fast turn arounds are our business. Motors such as the one pictured here have been rewound quickly and efficiently for our customers.


Digital Surge Testing

Surge testing of A/C electric motors and generator windings displays a accurate picture of the winding and insulation conditions. Tests made can determine good, marginal or defective windings and the winding insulation before a major failure occurs. In many cases actions can be taken to head off these failures, preventing costly delays and repairs. This digital surge tester applies a predetermined voltage and captures a sinusoidal wave form for each phase of the unit under going the test. It also displays megohms and Hi-Pot measurements. All the information is used to make the correct decision on what repairs are needed.


This is a Surge Test:

The wave form showing a good winding. You will notice how each of the three phases overlap each other. Representing what appears to be only one wave line. Pictured is the windings that are being tested, no faults are present.


Turn to Turn / Phase to Phase Weakness:

If there is a Turn to Turn / Phase to Phase weakness The wave patterns will separate and appear unstable This is an indication of imminent failure. The motor should be serviced immediately. Pictured is a turn to Turn / phase to phase fault.


Ground Faults:

If there is weak insulation the wave pattern will indicate the weakness. If a motor with a turn to turn fault short stays in service circulating currents may produce hot spots and the ground wall insulation will eventually burn up causing a shut down. Pictured is a ground fault.


ROTALIGN PRO the most versatile laser shaft alignment system:
Soft Foot Wizard for detection, measurement and correction.

Machine Train Alignment of up to 6 machines complete with tolerances, targets. etc.

Long Range: Easily accommodates a 33 ft. measurement separation between laser and receiver.

Monitors horizontal and vertical moves live and simultaneaouly.

Optimal move feature graphically displays best combination of moves for bolt-bound situations (move motor, pump or both).

Direct entry of target specifications, or thermal growth values at the feet. Thermal growth computation.

Intrinsically safe 'EX' PTB certified, for use in hazardous or explosive areas.

INSULATION STRIPPING OVENS:

Stripping ovens are an integral part in the repair process. Water injection temperature controlled burning of electric motor & generator stators alleviate the damage caused if the oven has a thermal runaway, simply put the water injection system keeps the temperature at the preset levels overcoming the potential of lamination core iron damage due to extreme temperatures, in some cases up to 1500 deg. F in the stator core can be reached.
