Drive Retrofits, AC & DC
If the DC motor is in good shape, it is usually less expensive to replace the DC drive than to convert the system to an AC inverter and new AC motor. There are both electrical and mechanical modifications that must be addressed which can add significant cost beyond simply replacing the DC drive. Carotron has had good success in large plastics extrusion plants replacing several older DC drives of various manufacture. Most are ordered in the Chassis configuration, but we also offer complete drive packages, including fusing and a circuit breaker, in a Nema 12 enclosure. Most common sizes are in the 100 to 400 horsepower range.
