Keys to Replacing 2HP (And Under) DC Motors with AC Motors and VFDs
When replacing old DC motor variable speed applications with AC motors and VFDs, you must consider the torque required and speed range for the application. Most applications have some sort of gear reduction attached to the motor. Therefore, when replacing DC motors with AC motors and variable frequency drives, you can achieve your desired output […]
