Downtime can be incredibly costly to your company.

Motor Management:

We partner with you to create a critical motor inventory.  We do this by analyzing your systems and deciding which motors will shut you down should they fail.  We then catalog the nameplate data from those motors.

We give you the standard lead times for all critical motors.  Long lead time motors can be ordered and stored at our facility or yours.

We also work with you to decide if it is better to repair or replace a motor.  By having a spare motor we can repair the spare and store it until you need it.

On Site Services:

In addition to the services we offer in our shop, we also offer on-site services, designed to cut time and cost that it would take to send your equipment out. Some of the ways EMS can assist onsite are with bearings replacements, laser balancing, and more.

Core Loss Testing:

EMS uses a fully automated computerized Phenix Model CL25A core tester to determine core losses found in stators, rotors, and armatures. The Model CL25A provides 25 KVA of power with a capacity of 2,000 amps. Motors through 1,250 horsepower are tested and a printout of results is provided to the customer.

Core loss is the major cause of wasted electrical energy which can result from overheating during operation, motor pre-mature failure, and physical damage such as rotor drag. Without core loss testing, it is impossible to determine that a motor is capable of operating at rated efficiency. The tester indicates the condition of core steel by measuring the watts of energy lost per pound when the core is excited to operating conditions.

The microprocessor works in conjunction with infrared heat scans to record “hot spot” conditions in the stator. These often occur where there has been physical contact between rotating parts and the core as well as “grounds” where the windings have arced and blown holes in the core. The computer indicates a maximum and minimum value in terms of flux, watts, and amps. If the core does not meet a minimum value, the steel laminations making up the core must be repaired, restacked, or replaced.

Motors that have failed and are not core tested often experience repeat failures. Defective bearings, the most common cause of electric motor failure, often results in core damage. A damaged or inefficient core will lead to a winding failure in a stator, wound rotor, or armature. For a complete report on the condition of your electric motor and documented core loss test results, send your motors to EMS.

Aegis Grounding Ring:

VFD-Induced Shaft Currents Can Kill Your Bearings!

VFDs allow large energy savings and precise control. But they also generate electric voltages on motor shafts. These shaft voltages can discharge through the bearings, causing pitting, fluting, and eventual bearing failure.

Protect Motor Bearings with AEGIS®Bearing Protection Rings

By channeling VFD-induced discharges safely to ground, AEGIS Bearing Protection Rings prevent electrical bearing damage. Proven in millions of installations worldwide, they provide unmatched protection of motors and coupled equipment from electrical bearing damage, motor failure, and unplanned downtime.

We Offer Complete Bearing Protection Services

We offer the following services to help prevent electrical bearing damage:

• Diagnosing damaged bearings
• Testing for shaft voltages
• Installation of AEGIS Rings externally or internally
• Protecting your motors with AEGIS Best Practices
• Registration for the AEGIS 2-Year Extended Warranty

We offer complete service 24 hours a day, 365 days a year!
