Brush DC Motors at Work
MEDICAL ANALYZERS
Portescap solves multiple application needs in analyzers, from sample draw on assays to rapid scanning
and detection of molecular mechanisms in liquids and gases, with its coreless brush dc motors.
For high throughput applications—those where over 1,000 assays are analyzed in an
hour—high efficiency and higher speed motors such as brush DC coreless motors
are a suitable choice. Their low rotor inertia along with short mechanical
time constant makes them ideally suited for such applications. As an
example, a Portescap 22-mm motor brush coreless DC motor offers no-load
speed of 8,000 rpm and a mechanical time constant of 6.8 milliseconds.
Another analyzer function that plays a vital role in their output is collecting
samples from the vials or assays, and serving them up to measurement
systems based on photometry, chromatography, or other appropriate schemes.
Here again, a brush DC coreless motor is highly applicable due to the power
density it packs in a small frame size. You can maximize your application’s
productivity with a 16 or 22mm workhorse from Portescap.
INFUSION PUMPS
Coreless brush DC motors offer significant advantages over their iron core brush counterparts for some
of the critical care pump applications where, the benefits range from improved efficiency to higher
power density, in a smaller frame size. One of the factors that deteriorates motor performance over long
term usage is the heating of the motor with associated Joule loss. In motor terminology this is governed
by the motor regulation factor determined by the coil resistance, R, and the torque constant, k. The
lower the motor regulation factor (R/k 2 ) the better would the motor perform over its life while
sustaining higher efficiencies. With some of the lowest motor regulation factors
Portescap’s latest innovation in Athlonix motors is already benefiting applications
in the infusion pump space by offering a choice of a higher performance motor
with less heat loss, higher efficiency and power density in compact packages.
ELECTRONICS ASSEMBLY
SURFACE MOUNT EQUIPMENT
Portescap’s versatile 35mm coreless motors with carbon brush commutation excel in electronic
assembly, robotics and automated machinery equipment and have been a work horse in
some of the pick and place machinery used in surface mount technology. Our
35mm low inertia motors can provide high acceleration, low electro
magnetic interference, and frequent start stops that the machines need
while maintaining smaller and light weight envelopes.
