Why Reliable Precision Electric Industrial Electronics Matter

However, when a production line stalls, downtime costs rise by the minute. Therefore, industrial leaders look for partners who can respond immediately, diagnose accurately, and restore power fast. Precision Electric Industrial Electronics, a family‑owned U.S. company, has delivered that peace of mind for more than forty years. Moreover, the engineer‑led team provides nationwide distribution of drives, motors, and controls alongside factory‑level repairs, so customers avoid juggling multiple vendors.

Because decision makers still need clear data, this guide distills the latest research on variable frequency drive faults, motor failures, and power quality issues. In addition, it outlines proven counter‑measures, recommended products, and success metrics drawn from real customer stories. Consequently, you will learn how to prevent the most common electrical breakdowns, how to choose the right retrofit path, and how to justify spending with hard numbers.

Circuit Board Repair: Cut Downtime, Control Costs

/in , /by

Estimated reading time: 6 minutes

Downtime hurts revenue, reputation, and worker confidence. Consequently, facility managers scramble when a drive control card or PLC module fails without warning. Instead of ordering a replacement that may arrive next quarter, progressive teams choose circuit board repair. The process restores the original assembly, keeps firmware intact, and avoids tedious re‑programming. Moreover, repaired hardware slides back into its rack within days, shrinking lost production hours according to research and cutting express freight charges.

Because our technicians work at component level under high‑magnification microscopes, we replace only what failed and any nearing‑end‑of‑life companions. As a result, the refurbished board often exceeds original reliability. Equally important, the choice supports sustainability by diverting electronics from landfills. Plant engineers appreciate that one decision satisfies budgetary, operational, and environmental objectives.

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.

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,
