Stepping up motor performance
July 1st 2007 Mclennan Servo Supplies, has
added the new Portescap h3 series
enhanced performance hybrid
stepper motor to its motion control
products.
Thanks to its
neodymium high
energy rotor
magnets, Sigmax
enhanced flux
focussing stator
and high heatloss
aluminium
housing, Mclennan says
the NEMA 17, 23 and 34
frame sized motors deliver a
15% to 40% higher output torque
with 10% lower power consumption
when compared to other highperformance
hybrid stepper motors
The h3 series also features larger
diameter, sealed ball race bearings
with an improved bearing retainer
and O-ring design to provide higher
axial and radial shaft loading,
prevent bearing spinout, eliminate
axial play and reduce motor
noise.
Available in a wide choice of
stack lengths with unipolar and
bipolar windings, the 200
step/rev h3 range can
provide improved
speed/torque performance with
higher throughput and duty cycle
capability as a form-fit replacement
for existing stepper motor
applications. |
