Is your DC motor drive obsolete and no longer supported by the manufacturer?
At Ameronics, we provide obsolete DC motor drive replacement solutions that keep your machines running without the expense and downtime of a full system replacement.
Why Obsolete DC Motor Drives Are a Challenge
In industrial environments, machines are often built to last decades — but the electronic components inside, such as DC motor controllers, may be discontinued long before the machine itself wears out. This can cause:
- Extended downtime while sourcing rare parts
- Costly retrofits or complete equipment replacement
- Compatibility issues with newer controllers
- Reduced production efficiency

Ameronics specializes in custom-engineered DC motor controllers designed to match or improve upon your original drive specifications. We work with:
- OEMs to develop private-label solutions
- System integrators seeking custom automation controls
- Manufacturers extending the life of legacy machinery
Our drives can be tailored to:
- Match voltage and current ratings
- Fit your existing enclosure or panel space
- Integrate with existing control systems
- Provide modern efficiency and safety upgrades

Key takeaways
- Choosing the right DC motor drive controller depends on motor type (PMDC, shunt-wound), voltage class, and whether four-quadrant regenerative braking is required.
- For 12–90 V battery-powered or low-voltage applications, a PWM DC motor controller delivers smoother current and higher efficiency than phase control.
- For 90/180 V industrial DC motors, an SCR DC motor drive provides rugged motor speed control from 1/8 to 3 HP.
- Conveyors, hoists, and process equipment that require braking should use a regenerative DC drive to recover energy and protect mechanical loads.
