Bearing Protection Services
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 with AEGIS®
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.

Description of Semiannual Tests for Electrical Motors
Utility and Industrial customers alike have large AC Induction, Synchronous and Wound Rotor Motors that have been running in their respective facilities for many years. When such a machine fails, finding a drop-in replacement can be almost impossible. At Malloy, we love tackling these tough motor application issues. Along with an adapter base, our Motor Team provides a suitable motor with like features and design characteristics. The Adapter Base raises the new motor up to the correct shaft height and utilizes the existing motor’s foot print. This motor/base package provides a true “drop-in” replacement for our customer.
Malloy’s extensive motor inventory now includes medium voltage motors up to 2000 HP. The demand for medium voltage motors is growing and Malloy has made the commitment to provide the right motors for many industrial medium voltage applications. Along with medium voltage motors Malloy offers medium voltage drives to provide the perfect system.
