DC Motor Drive Controllers
Standard and configurable PWM, SCR and regenerative DC drives from fractional to integral horsepower, designed for industrial motor control duty cycles.
About Ameronics
A US manufacturer of DC motor drive controllers and power electronics, built for OEMs.
For decades, Ameronics has designed and manufactured DC motor drive controllers, PWM, SCR and regenerative drives, and custom power electronics for original equipment manufacturers, system integrators and process plants. Our drives are engineered to deliver precise DC motor speed control and dependable industrial motor control in the most demanding production environments.
Who We Are
An engineering-led manufacturer — not a distributor.
Ameronics is a privately held US manufacturer focused on a single discipline: motion and power conversion. We design our own boards, write our own firmware, build the assemblies in-house and stand behind every unit we ship. When an OEM calls with a difficult application question, the response comes from the engineers who actually designed the product — not a call center.
That model is what allows us to support short lead times, long product lifecycles and form-fit-function replacements that keep your machines running for 15+ years.
Our Mission
Power that performs — every cycle, every shift.
Our mission is to give engineers, integrators and plant teams DC drive solutions they can specify with confidence. Whether it's a standard PWM DC motor controller, an SCR DC motor drive for higher-voltage industrial motors, a four-quadrant regenerative DC drive, or a fully custom PCB and power assembly — every product carries the same promise of precision, durability and engineering accountability.

Core Capabilities
From a single replacement board to full power-electronics programs.
Custom PCB Design
End-to-end design of analog, digital and mixed-signal control boards — schematic capture, layout, prototyping and manufacturing under one roof.
Power Electronics
Rectifiers, choppers, soft-starts and regen modules engineered for harsh thermal, vibration and EMC environments.
Form-Fit-Function Replacements
Drop-in replacements for legacy and obsolete OEM drives so you can keep production lines and installed bases running.
Contract Manufacturing
In-house SMT and through-hole assembly, conformal coating, testing and burn-in for low-to-mid volume production runs.
Lifecycle Engineering Support
Direct access to the design team for application sizing, tuning, field issues and long-term sustainment.

Why OEMs Choose Ameronics
A supplier built around your engineering and procurement reality.
Built in the USA, supported in the USA
Domestic design and manufacturing means clear supply chain visibility, ITAR-friendly handling on request, and engineers in the same time zone as your plant.
Spec'd by engineers, validated under load
Every standard product is application-tested and burn-in verified. Custom programs include design reviews, prototype validation and production qualification.
Long product lifecycles
We design for 15+ year service life and maintain build documentation so your installed base stays serviceable long after launch.
Direct engineer-to-engineer support
Skip the gatekeepers. Our application engineers help you size drives, tune loops and resolve field issues — by phone, email, or on-site when needed.
How We Engage
A clear, low-friction engineering process.
- Step 01
Discovery
Share the application, motor data and operating envelope. We respond with a written technical recommendation.
- Step 02
Specification
We confirm topology — PWM, SCR or regenerative — voltage class, control interface and packaging.
- Step 03
Build & Validate
Standard units ship from stock. Custom programs go through prototype, qualification and production release.
- Step 04
Sustain
Lifecycle support, spares, documentation and engineering changes for the life of your platform.
Quality & Reliability
Engineered for the duty cycles your machines actually see.
Industrial drives don't fail in the lab — they fail in the field after years of thermal cycling, line transients, dust, vibration and operator abuse. Our designs are derated for real-world conditions, our boards are built for serviceability, and every unit is functionally tested before it leaves the building.
- 100% functional test on every drive
- Burn-in on regenerative & high-power units
- Conformal coating available
- Industrial-grade components & derating
- Documented BOM & build records
- RoHS-compliant options
