Will it replace my old motor?

If your old motor also has an IEC 90L frame, that is the first piece of information for assessing mounting compatibility. To confirm the fit, compare the mounting type, shaft diameter and length, foot hole spacing, flange dimensions if any, as well as power, speed and electrical data. Send photos of your current motor’s nameplate and connections on WhatsApp and we will confirm the right model.
