AEGIS Protection Rings

Beaver Electrical Machinery is Canada’s only trained installer for AEGIS® bearing protection rings. When Beaver installs an AEGIS® protection ring, it is granted additional manufacturer’s warranty length.

Without bearing protection, shaft voltages can cause fluting damage.

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

  • Bearing Cutting and Inspection
  • Shaft voltage testing
  • External AEGIS® Installation
  • Internal AEGIS® Installation

Your Bearings Can Fail from VFD-Induced Shaft Currents
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 Your Bearings
AEGIS® Shaft Grounding Rings are the leading bearing protection technology. They protect bearings by giving shaft voltages a “path of least resistance” to ground, so the shaft discharges through the ring, not the bearing. Unlike other shaft grounding products, AEGIS® rings are long-lived and maintenance-free, and can be installed inside or outside of the motor.

Green Motors Practices Group

Through the Green Motors Practices Group, Beaver rewinds are simply better.

GMPG members maintain or improve original motor reliability and energy efficiency when rewinding or rebuilding electric motors. The rewind process is strictly controlled and consequently the motor iron losses are not affected.

We are able to offer electric utility financed incentives or rebates when our customer’s qualifying rewinds are meet the Green Motor Initiative’s (GMI) high process standards.

GMPG members achieve these efficiency goals through strict adherence to good repair practices, including Green Motor Practices Group Electric Motor Repairing Specification 2012 and ANSI/EASA Standard AR100-2015

Both of Beaver’s service centres are GMPG members and both are EASA AR100 certified.

 

Power in doesn’t always equal power out.

ANSI/EASA Standard AR100-2015

Program Overview

EASA AR100 assures the efficiency and reliability of repaired electric motors.

It has been proven that electric motor efficiency can be maintained during repair and rewind by following defined good practices. EASA has developed an international accreditation program for service centers based on the sources of these good practices, namely ANSI/EASA AR100: Recommended Practice for the Repair of Rotating Electrical Apparatus and the Good Practice Guide of the 2003 study The Effect of Repair/Rewinding on Motor Efficiency, by EASA and the Association of Electrical and Mechanical Trades (AEMT).

The intent of this groundbreaking accreditation program is to evaluate service centers for evidence of compliance to assure that they are using prescribed good practices to maintain motor efficiency and reliability during electrical and mechanical repairs of electric motors. The program accomplishes this by use of independent, third-party auditors.
