Brushless
DC motors. This line of compact 1.7-in. (43mm) diameter
brushless motors offers no-load speeds up to 15,000 rpm and
stall torque up to 8 oz-in. These 8-pole, 12-slot and 4-pole,
6-slot, three-phase motors can be ordered for 12, 24, or 36
volt inputs. Standard designs use Hall effect devices and
rare earth magnets for electronically controlled commutation
and minimal torque ripple. Ametek Rotron, Kent,
OH. Free info--Circle 921.

Microstepping
motor driver. The DCB-261 is a bi-polar chopper driver
with intelligent controller for operating small stepping motors.
The voltage range is from 24 to 40 VDC and the output current
is up to 1.2A per phase. Advanced Micro Systems,
Nashua, NH. Free info--Circle 908.

Mini DC motors. The 16LN motor can be delivered with
any of three different gearboxes, incorporating spur or planetary
gears. With a gearbox, the motor can cover a dynamic torque
range of up to 0.6 N-m. Windings are available from 4V to
12V. API Motion, Amherst, NY. Free info--Circle

Brushless DC motors. These NEMA 34 flange mount
designs are available in three lengths of 2.0- to 3.2-in.
The DIN34 is capable of peak torques ranging from 250 to 350
oz-in and speeds to 18,000 rpm. BEI Kimco Magnetics

Stepper
motor series. The series 44M100D permanent magnet stepper
motor is lightweight and quiet. It was designed for limited
space applications, capitalizing on its thin profile and high
torquetoinertia ratio. Applications for this series
include electronics assembly and medical design. Thomson

Rugged
AC motors. These AC motors are available with custom windings
and voltages in a variety of designs for OEM applications.
Variable speed designs and inverter duty insulation systems
are also available. Groschopp, Sioux Center,
IA. Free info--Circle 911. http://www.OneRS.net/104df-911
Compact
motor driver. The AXH Series 30 and 50 watt mini-brushless
DC motor and board-level driver packages are more than 50%
smaller than equivalent power AC induction speed control motors.
Models offer stable speed and various torque ratings. Oriental
Motor, Torrance, CA. Free info--Circle 912. http://www.OneRS.net/104df-912
High-torque
stepper. The NEMA size 17 motor provides holding torques
up to 58 oz-in. Based on 1.8 degree step angles, the two-phase
hybrid stepmotor achieves bi-directional position accuracy
of ±3%. Eastern Air Devices, Dover, NH.

Network
interface controllers. These controllers are low-power
(operating from 115 VAC line for the SO16 Series and 230 VAC
line for the SO17 Series) motor controllers used to control
the speed of one-tenth to one horsepower single-phase AC induction
motors. Anacon Systems, Mountain View, CA. Free

Large AC
motors. The G30 Global Series motors offer more hp
per frame than other similarly configured motors. Features
include bi-directional rotation, corrosion-resistant metric
hardware, dowel pins and vertical jackscrew holes. Reliance
Electric, Greenville, SC. Free info--Circle 916.

Motor
soft-starter. This simplified motor soft-start is a compact
economical solution for reducing stress in low-hp 3-phase
motors and drive components. The soft-start is phase-insensitive
and is available as an open-frame assembly or mounted in its
own enclosure. Enerpro Inc, Goleta, CA. Free

Smart motors.
The 2300 and 3400 series IP65 SmartMotors offer a fluid
protected integrated motor design, which contains the controller,
amplifier and encoder built into a brushless DC servomotor.
This eliminates NEMA cabinet and extra cable needs. Animatics

Unitized
brushless motor package. ELCOM ST slotted brushless DC
motors can now be custom ordered with control electronics
seated inside the motor housing. Smaller, lighter, more versatile
and more cost effective to operate than conventional brushless
DC motors, these units can even replace brush DC motors in
many applications. The custom units offered include 2-wire
(single polarity) with open-loop speed control from 12 to
48V, with current to 8A (depending on windings used), and
2-wire reversible motors with a 3A limit. Pittman, Harleysville,
