High Power Density Brush DC Motors
Portescap (West Chester, PA) has introduced the next
generation of Athlonix high power density brush DC
motors. Available in a 22 mm diameter, the 22DCP motor
will feature an energy efficient coreless design with a self-supporting coil and magnetic circuit. Features include:
■ Availability with precious metal commutation.
■ Availability with graphite commutation with Alnico
■ A constant force spring design for carbon brush.
■ An optional REE (Restriction of Electro Erosion) coil.
■ Maximum continuous torque up to 6. 5 mNm.
■ RoHS compliance.
Permanent Magnet Motors
NovaTorque (Fremont, CA) has introduced 900
RPM versions of its 1.5, 2, 3, and 5 hp Electronically
Commutated Permanent Magnet (ECPM) models.
The models provide a full load motor-only efficiency
rating of 92 to 94% compared to approximately 82
to 87% for conventional AC induction motor ratings.
■ High efficiency under partial load.
■ Flux focusing stator and rotator technology.
■ An all-ferrite (versus rare earth) magnet design.
■ Standard NEMA frame sizes and mounting

J.W. Winco (New Berlin, WI) has announced its
GN 2424 aluminum or steel cam roller carriages
for GN 2422 cam roller guide rails, in metric sizes.
The carriages are used in mechanical engineering or
jigmaking for the linear movement of plant equipment.
■ RoHS compliance.
■ The ability to be mounted in axial or radial direction to
the roller axes.
■ A base body offered in aluminum or steel with zinc
plated, blue passivated finish.
■ Rollers made of anti-friction bearing steel, hardened,
with balls mounted.
■ Dust and splash water protection by (2RS) NBR
■ Permanent lubrication.
■ A wiper made of gray plastic (PUR) with a zinc plated
■ Three types: Normal cam roller carriage with central
arrangement, radial cam roller carriage with lateral
arrangement, and narrow cam roller carriage with
Horizontal/Vertical Rotary Tables
Indexing Technologies (Ramsey, NJ) has
announced the ITI-Exact TM NCT Series Horizontal/
Vertical Rotary Tables, available in eight frame sizes,
each with a standard-size tabletop fitted with T-slots
and a precision center pilot hole for alignment and
clamping of the fixture or piece parts. Features
■ Rotation via a high-speed dual-lead worm gear and
wheel driven via a Servo motor.
■ An encoder for positioning and accuracy of the
■ An integral distortion-free hydraulic brake unit.
