When placing an order, please state the following
minimum data in the order, as in the example.
The product code of the motor is composed in accor-
dance with the following example.
Technical data for totally enclosed squirrel cage three phase motors IP 55 – IC 411 – Insulation class F, temperature rise class B IE2 class
Single-speed motors of size 56 to 132 are stamped with
50 and 60 Hz at voltage code S and D. The current
rating for each voltage range is specified on the rating
plate. It represents the highest current that can exist
within the voltage range at the rated output. The power
factor and speed specified on the rating plate apply at
400 V 50 Hz and 460 V 60 Hz.
M3AA 280 has feet and D-end shield of cast iron.
M3AA 250 SMB 2-pole, high output version, as well as
M3AA 280 2-pole have cast iron feet and bearing
The flange bearing shields of sizes 180 to 280 are made
of cast iron
The terminal block is provided with
6 terminals for connecting Cu-cable.
The terminals are marked in
accordance with IEC 60034-8.
Single-speed motors of size 160 to 280 are stamped
with 50 and 60 Hz at voltage code S and D. The rating
plate is arranged in the form of a table with values for
current, power factor and motor speed at six voltages.

Motors that will be operated in very humid or wet
environments and especially under intermittent duty
should be provided with drain holes. The appropriate IM
designation, such as IM 3031, is specified on the basis
of the method of mounting the motor.
Motors are provided with closable plastic plugs in the
drain holes (see diagram below). The plugs will be open
on delivery. When mounting the motors it should be
ensured that the drain holes face downwards. In the
case of vertical mounting, the upper plug must be hammered home completely. In very dusty environ-
ments both plugs should be hammered home.
Sizes 56 to 63 are supplied as standard with drain holes
on D-end while sizes 71 to 280 are supplied with drain
holes both on D-end and N-end.
When mounting arrangement differs from foot mounted
IM B3, please mention variant code 066 when ordering.
See variant codes 065, 066 and 076 under the heading
