Motor Controls Expertise

Motor Starting and Drive Systems Done Right

Moonlight Electric Solutions installs, retrofits, and commissions motor control systems for industrial plants throughout Cheyenne and southeastern Wyoming. From single across-the-line starter replacements to complete VFD retrofits on production-critical motors, our team brings the wiring discipline and commissioning rigor that keeps motors running and production lines moving.

Motor controls are where electrical and mechanical systems meet, and where most plant downtime originates. We approach every motor installation as a future-troubleshooting exercise — clean wiring, documented landings, ferruled conductors, and parameter records so the next service event is a 30-minute job rather than a 30-hour one.

A VFD is only as good as its commissioning. We tune the parameters, capture the settings, and walk your maintenance team through the screen menus before we leave the site.

Cheyenne plants run a wide range of motor-driven equipment — pumps, fans, conveyors, mixers, compressors, and process equipment that all benefit from properly sized and properly commissioned motor controls. We work with maintenance directors and plant engineers across Laramie County, Pine Bluffs, Burns, and northern Colorado.

Our motor controls work covers new motor installations, starter and contactor replacements, soft start retrofits, complete VFD installations, drive commissioning and tuning, and motor protection upgrades. Every installation includes parameter backup, motor nameplate documentation, and a commissioning report for your maintenance records.

Motor Controls Capabilities

Motor Controls and Drive Services

01

Across-the-Line Starters

New starter installations, contactor replacements, and overload retrofits. Sized to motor full-load amperage with NEMA-rated protection appropriate for your duty cycle.

02

Soft Start Retrofits

Solid-state soft starters for high-inertia loads, applications with mechanical concerns about starting torque, or facilities where inrush current trips upstream protection.

03

Variable Frequency Drives

VFD installation, sizing, and commissioning for energy savings, process control, or precise speed regulation. Allen-Bradley PowerFlex, ABB ACS, and Siemens platforms.

04

Motor Control Center Buckets

MCC bucket additions and replacements — full-voltage non-reversing, reversing, soft-start, and VFD buckets. We pre-wire off-site to compress installation time.

05

Motor Protection and Monitoring

Electronic overload relays, motor protection relays, and condition-monitoring systems that trend bearing temperature, vibration, and current signature.

06

Motor Wiring and Terminations

Power and control wiring from MCC to motor, including conduit, cable tray, motor disconnect installation, and proper grounding for VFD applications.

Installation Process

How Motor Controls Projects Work

01

Application Review and Sizing

We review motor nameplate data, load profile, duty cycle, and surrounding equipment to recommend the appropriate starter or drive type. For VFD applications, we evaluate motor compatibility and bearing protection requirements.

02

Engineering and Equipment Selection

We produce a control schematic, panel layout, and bill of materials. You receive a fixed-price proposal with drive specifications, harmonic mitigation requirements where applicable, and lead times.

03

Installation and Wiring

Our electricians install the starter, soft start, or VFD with proper conductor sizing, shielded VFD cable where required, and dedicated equipment grounding. All landings are torqued to specification and documented.

04

Commissioning, Tuning, and Training

We commission the drive with motor-specific parameters, tune for the load characteristics, capture a parameter backup, and walk your maintenance team through the operator interface and fault history menus.

Frequently Asked Questions

Motor Controls & VFDs FAQs

When does it make sense to retrofit a VFD onto an existing motor?

VFDs deliver the strongest payback on variable-torque loads — pumps and fans where flow can be reduced. Energy savings of 20 to 50 percent are common. VFDs also make sense when you need precise speed control, soft starting to protect mechanical components, or to eliminate across-the-line starting current spikes.

Are existing motors compatible with VFDs?

Most modern industrial motors are VFD-compatible, but motors built before the mid-1990s or in unusual frame sizes may need inverter-duty replacement, shaft grounding rings to prevent bearing fluting, or dV/dt filters at the drive output. We evaluate motor compatibility during the application review.

What about harmonics from the VFD?

VFDs generate harmonics that can affect plant power quality. For installations where harmonic distortion is a concern — typically larger drives or installations with sensitive equipment — we specify line reactors, drive-mounted filters, or 18-pulse drive configurations to keep harmonic distortion within IEEE 519 limits.

Do you commission drives or just install them?

We commission every drive we install. That includes parameter setup specific to the connected motor and load, autotuning where appropriate, fault history review, and a parameter backup saved to a memory device for future restoration.

Can you troubleshoot existing VFD problems?

Yes. We troubleshoot drive faults, motor problems, and the wiring between them. We carry diagnostic tools for drive parameter review, motor insulation testing, and cable continuity testing. Most calls are resolved on the first visit with the right diagnostic discipline.

Do you work with all major drive manufacturers?

We work primarily with Allen-Bradley PowerFlex, ABB ACS, Siemens Sinamics, and Yaskawa drives — the four most common platforms in industrial Wyoming. We can install or service other manufacturers as needed; contact us at (307) 757-5553 with your specific platform.
