Compact frame: how it differs from the standard 100L-2

90L-2K delivers the same electrical data (rated speed, current, torque) as the standard 100L-2 of the same power and speed, in one smaller IEC frame: 90L (standard: 100L). In the B3 foot-mounted version the shaft height is 90 mm (standard 100 mm), shaft diameter × length Ø24 × 50 mm (standard Ø28 × 60 mm), foot hole spacing 140 × 125 mm (standard 160 × 140 mm) and overall length 361 mm (standard 406 mm). It is therefore not a direct replacement for the standard model; the base, coupling or pulley and any flange size must be checked again. All compact models and the dimension comparison: Compact Electric Motors.

Frequently Asked Questions

How many amps does a 3 kW 3000 rpm motor draw?

On a 400 V supply it draws about 5.71 A at full load.

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.
