Slotless Brushless DC Motor
Pittman Motors has introduced its latest offering in a broad range of DC
brush and brushless motors. The BI-05 Series slotless brushless DC motor
is designed for maximum precision and performance in a package size
perfectly suited for precision equipment such as surgical and dental tools,
medical instruments and other health care devices in which small component size is crucial.

Improved Brushless Motor
Allied Motion Dordrecht announces the availability of an improved version
of the proven brushless KinetiMax 54 motor series. The new 54 mm
diameter KinetiMax 54 EB outer rotor motor with integrated drive electronics now has bidirectional speed control, overtemperature protection,
and reverse polarity protection. These improvements together with its
robust bearing system, capable of withstanding high side loading, its speed
adjustability (300 to 4000 RPM) and speed output signal ( 36 pules per
rev) ensure that the new KinetiMax 54 EB will continue as a favorite choice
among designers as it has been for over 10 years in a broad range of applications in medical, instrumentation, vehicle, factory automation and other
markets where a minimum operating life of 20.000 hours is a benefit.

High Efficiency 22-mm ECS Brushless Slotless Motor
Portescap has introduced the 22ECS brushless motor. Designed to deliver exceptional efficiency in high speed applications, the 22ECS runs up to 30 percent cooler than similar motors, at
speeds greater than 50K RPM. As a result, this brushless slotless motor stays much cooler and
offers greater power density than equivalent models at a given operating point. The 22ECS also
uses unique high performance lubrication and ball bearings to extend motor life and maximize
performance at high speeds. Due to its high power, efficiency and low rotor inertia, the 22ECS
can change speeds and accelerate rapidly.

Small Ultra-Flat Stepper Motor
A very small, ultra-flat stepper motor is now available from Nanotec Electronic US Inc. The STF2818 model has a flange size of 28 mm and is only
9. 4 mm high. The STF2818 is the second ultra-flat stepper motor in the
product line, in addition to the ST6318. Originally, the small stepper motor
was developed for feeder applications in the semiconductor industry,
where components are supplied on rolls. With a rotor inertia of 1.7 gcm²
and a holding torque of 0.98 Ncm, it reaches a considerable speed for its
size. In combination with a step angle of 1.8°, the STF2818 is therefore
also suitable for many other applications, including installation in a stirrer.
The ultra-flat stepper motor is optionally available with a flat-sided shaft.
