AC Electric Motor Stator Winding Repair

/in /by

Precision Electric has more than 100 years of AC electric motor winding experience. We have rewound thousands of AC electric motor stators in the 29 years Precision Electric has been serving the industry. Many things go into winding AC electric motors. Here is a short example of how Precision Electric winds AC electric motors.

Making AC Electric Motor Coil Connections

Once a AC electric motor has entered our repair facility due to a possible failed winding and it has been through the initial testing process, we will disassemble the motor and begin the AC electric motor stator winding investigation. The first sign of a failed motor winding is the very recognizable odor from a burned up winding. If the odor doesn’t get our attention a full analysis of the motor stator will. The failed area of the AC electric motor stator is then looked at further and a root cause failure report is completed. We will then start taking all nameplate and stator winding information and fill out a EASA Data Card.

The EASA Data Card will give the AC Electric Motor Stator Winding Tech the following information:

  • Nameplate Data
  • Coil and stator core dimensions
  • Connection type
  • Number of circuits used
  • Coil pitch
  • Coil grouping type (salient-pole, consequent-pole)
  • Wire size
  • Number of wires in multiple that make up coils
  • Number of turns of magnet wire in each coil

Once all the required data is recorded, we can begin the actual AC electric motor stator winding process. The proper wire size is pulled from our stock and placed on our winding machine. The coils are then turned and placed on a clean winding rack. In the meantime, the AC electric motor stator is stripped of all the old winding and placed in burn down oven to remove all of the old insulation. After going though a full cycle in the burn down oven the stator is then sandblasted and all lamination and stator teeth are repaired and freed of all sharp edges or areas that could, over time, wear though the insulation and damage the coils causing a premature failure. When the AC electric motor stator is prepped and ready, it goes to our winding department and the new coils are installed according to the EASA winding data card. When all of the coil connections are made and tested, the AC electric motor stator is ready to be dipped in varnish and baked in the oven.

The AC electric motor is then reassembled with new bearings and any lip seals or mechanical seals are also replaced. The motor is then tested at our test panel and all performance data is verified. We then ship and the motor to our customer. If an installation service is required, we schedule a Field Tech to install the AC electric motor at the customer’s site.

 

Precision Electric offers AC electric motor repair and winding quotes.

Repair Variable Speed Drives on Air Compressors

/in /by

Precision Electric is your best source to repair variable speed drives on air compressors. We have an extensive background in the repair of variable speed drives on air compressors as well as other industrial equipment.

Precision Electric uses the most advanced testing equipment that is available to repair variable speed drives on air compressors.

Some of our customers are Sullair air compressor repair centers, but they do not repair the variable speed drives on air compressors. Instead they send their variable speed drives from their air compressors to Precision Electric because we not only guarantee a quick turnaround, but we also have extensive technical support and our repair works comes with an in service warranty, too.

Our in service warranty is one of  a kind and is great for customers who want their backup (spare) equipment rebuilt, because the warranty doesn’t actually start until the rebuilt equipment is put into service.

Many of the Sullair repair facilities across the nation have learned that by sending Eaton a repair of variable speed drives on air compressors that Eaton has an extremely slow lead time, and more often than not Eaton ends up returning the variable speed drive not repaired. This isn’t economical for Sullair repair centers, for the air compressor can be repaired in a timely manner as should the variable speed drive.

Precision Electric offers emergency service on the repair of variable speed drives on air compressors and other industrial electrical equipment, because our goal is to increase production and decrease downtime for our customers.

If you’re seeking to repair variable speed drives on air compressors, contact Precision Electric for a free quote.

Lenze AC Tech Price Increase

/in /by

Lenze AC Tech announced a price increase a couple weeks ago for nearly all of their drive and servo products except for the SMVector drive lines and newer automation product lines. The Lenze AC Tech price increase will go into effect on May 1, 2012.

Lenze AC Tech stated that the price increase is due to market conditions and significant increases in energy and product material costs (raw materials). We at Precision Electric do not believe the Lenze AC Tech price increase will affect drive sales much, but it may give existing MC Series drive users motivation to convert to Lenze AC Tech SMVector drive line.

The Lenze AC Tech price increase will certainly affect users with existing AC Tech equipment who are not interested in converting over to Lenze AC Tech SMVector drives, or other newer product lines unaffected by the Lenze AC Tech price increase. There are literally thousands of applications out there using the MC Series drives, and in my opinion these applications should be converted over to the Lenze AC Tech SMVector drive line.

Converting the AC Tech MC Series over to Lenze AC Tech SMVector is logical because of the Lenze AC Tech price increase, and for the Lenze AC Tech SMVector drive features. The Lenze AC Tech SMVector is all around a better product than the AC Tech MC Series, and in nearly every horsepower rating, it is all less expensive than the AC Tech MC Series drive.

The Lenze AC Tech price increase will be effective on May 1, 2012 and all quotes Precision Electric has made prior to May 1, 2012 will be adjusted accordingly if need be. To discuss technical data with regard to converting over AC Tech MC Series drives to the Lenze AC Tech SMVector drive, contact Precision Electric today.

Preventing Electrical Bearing Damage Caused by VFD’s

/in , , /by

 

FACT: Every motor controlled by a variable frequency drive (VFD) should have bearing protection.

WHY?: Variable frequency drives induce voltage to the electric motor’s shaft that discharges through the bearings. This voltage can cause severe pitting, excessive bearing noise and eventually bearing failure (see picture below).

IT GETS WORSE: Not only the motor’s bearings are at risk but coupled equipment like gear boxes, encoders, brake motors, etc. are also at risk of damage. Installing a bearing protection ring on your electric motor will channel that shaft voltage away from your bearings and safely into ground.

 

Electric Motor Bearing Failure

Pitting in a electric motor’s bearing cause by shaft voltage induced by a variable frequency drive

 

 

 

 

 

 

 

REMEMBER: Insulating bearing housings alone does not prevent shaft current from discharging through the electric motor’s bearings and coupled equipment.

SOLUTION: Precision Electric can help you protect your bearings. Its cheaper than you think and it stops you from paying frequent electric motor repair cost.  For more information on pricing on bearing damage protection and general purpose and inverter duty electric motors,

We will do everything we can to minimize your down time and maximize your productivity.
