Basic design characteristics
·
·
·
·
·
·
Fully laminated stator, main
poles and interpoles.
Low induced voltage due to
well proportioned ratio
between length and diameter
of armature.
Low bar to bar voltage ensures
good commutation.
Large thermal masses
(copper and steel weight)
give high thermal time
constant.
Well designed end frames
and louvres ensure easy
inspection and reduce noise.
NDE spigots and stub shafts
as standard to accept
adaptors for all well known
makes of tachometers and
pulse generators.
·
·
·
·
·
·
·
·
High efficiency through low
field losses and well proportioned
airgap between armature
and stator.
Minimal brush and commutator
wear due to good commutation.
1-phase thyristor supply without
external inductance saves
price and space.
Excellent short time overload
characteristics which allow
choice of smaller motor in
many cases.
Designed for high armature
voltages as standard.
High mechanical and electrical
flexibility.
Painting with excellent corrosion
resistant properties.
Conforms with IEC, BS and
VDE standards.
Available according to NEMA.
Available CSA approved.
