Electric motors have been built according to the IEC standard since the 19th century, which stands for International European Committee and means that all motor manufacturers build with the same dimensions, i.e. the same shaft size, foot size and center height, terminal boxes and lengths can still differ! The IEC size comes from the center height, when the motor stands on its feet up to the center of the center, the IEC frame size is, a type of IEC 90 has a center height of 90 mm, in addition, this standard has a shaft of 24 mm!

Why doesn’t my electric motor start? A frequently asked question, first of all, is it a 1 ~ motor or a 3 ~ motor? With 1 ~ motors this is usually a defective capacitor, or the relay or centrifugal switch no longer works, of course the winding can no longer be connected or even burned. With 3 ~ motors a fuse may be defective, an electric motor will no longer start up on 2 phases, of course the winding may also be defective. Call us for more advice!
