-
Designed and manufactured
to IEC 34-1 and NEMA MG1 (USA) mechanical and electrical standards
-
Available in IP 54, 44
and 23 enclosures with IEC B3, B5, B14 mounting provisions. Also
available in NEMA (USA) footed, face and flange mountings as well as
a wide variety of special and custom mountings.
-
Thyristor motors in
frames 71 through 112 have provisions for mounting a variety of B5
and B14 flange or faces and B3 bases. Tachometer mounting provisions
are also standard on each motor with adaptor packages for a variety
of tachometers.
-
IEC motors have imperial
fasteners.
-
Recognized by
underwriters Laboratories (USA) component approval program, file
number E57948, guide number PRGY2, and by Canadian Standards
Association, file number LR33543
-
Full-fact metal rating
plate lists is a permanent record of motor data. Thyristor motors
have dual kW ratings listing 1,05 and 1,40 form factor output
capability and full load DC amperage for each kW rating.
-
Steel frames with rugged
high-pressure cast 380 alloy aluminum machined endshields, with
steel bearing seat inserts (IEC71 and larger) for precision
alignment and bearing life, accurate brush tracking and maximum
motor life.

-
Ceramic permanent magnet
field, ferrite type, operate cooler and more efficiently than do
wound field motors. Four pole designs used in larger ratings.
Designed for ambient temperature range of -20◦C to 40◦C
-
IEC frame motors have a
terminal board in a cast, gasketed terminal housing. Larger low
voltage motors have machined studs for connections. jSmaller motors
have high temperature leads.
-
Precision dynamically
balanced armatures for quiet, smooth operation.
-
Class F & H insulation
materials used throughout with fusion welded, molded commutators for
dimensional stability.
-
Oversized brushes,
accessible without disassembly of the motor, with integral constant
pressure springs and bi-directional brush holders assure longer
service before maintenance -- up to four times that of other DC
motors. Four brushes are used in larger low voltage motors.
-
Reversible by
interchanging armature connections and capable of dynamic braking
for faster stopping.
-
Sealed or shielded,
permanently lubricated, selected electric motor grade ball bearings
ar used for quiet operation and long life.
