Precision Diagnostics for Reliable Motor & Pump Performance

Not sure why your system is underperforming—or about to fail? At Premier Electric Motor Repair, we provide in-depth diagnostics and testing to identify issues early and resolve them before they cause expensive breakdowns.


From vibration analysis to dynamic balancing, our technicians use advanced tools to fine-tune motor and pump performance for clients throughout Montana, Northern Wyoming, and Western South Dakota.

Motor Diagnostics & Testing Services

When your motor isn’t running at full capacity, we find out why. Our diagnostic process includes full electrical and mechanical testing to pinpoint hidden issues and prevent premature wear or failure.


We test for:


  • Voltage imbalance
  • Ground faults and insulation breakdown
  • Rotor alignment and torque output
  • Load testing and thermal performance
  • Resistance, capacitance, and amperage flow

We also inspect all components—bearings, shafts, windings—for signs of wear, misalignment, or overheating.

Vibration Analysis

Small vibrations can signal big problems. Using digital sensors and specialized software, we measure and analyze motor and pump vibration to detect:



  • Bearing failure

  • Shaft misalignment

  • Loose components

  • Imbalance and excessive wear

Early detection allows us to make targeted repairs before damage becomes severe.

Dynamic Balancing

Unbalanced motors or pumps waste energy and cause damage over time. Our dynamic balancing service restores precision to rotating components like impellers, fans, rotors, and couplings.


Benefits include:



  • Reduced vibration and noise

  • Extended motor life

  • Improved energy efficiency

  • Decreased wear on shafts and bearings

We offer both in-shop balancing and on-site service for critical systems that can't afford downtime.

Diagnostic Support for All Industries

Our testing and analysis services are ideal for:


  • Manufacturing facilities
  • Municipal utilities
  • Agricultural and irrigation systems
  • Residential well and pump systems
  • HVAC and pool equipment

Why Preventative Testing Matters

Waiting until a motor fails can cost you far more than a routine test. We help clients avoid:

  • Unexpected downtime
  • Emergency repair costs
  • Equipment replacement
  • Energy inefficiency
  • System-wide damage

Regular diagnostics are your frontline defense against catastrophic failure.

FAQs – Motor Diagnostics & Vibration Analysis

  • How often should I test my motors?

    We recommend diagnostic testing at least once per year for high-use systems, or whenever performance changes unexpectedly.

  • Can you test equipment on-site?

    Yes. We provide full on-site diagnostics, vibration analysis, and balancing across our tri-state service area.

  • What if my equipment is running fine?

    Even systems that seem fine can have hidden imbalances or degradation. Preventative testing helps catch issues early, before failure.

  • How long does vibration testing take?

    Most vibration tests can be completed in under 2 hours depending on system complexity.

  • What are the signs I need dynamic balancing?

    Excess noise, uneven wear on parts, vibration, or overheating are strong indicators your system needs dynamic balancing.
