Precision Spur Gear Motors
Precision spur gear motors from ServoCity are available now for $34.99. There are eight available choices
offering a wide selection of RPMs (from 6-90 RPM).
D-Series Hitec Servos
ServoCity is also offering Hitec’s D-Series servo line which sets new standards for advanced programmable
technology. Powered by their 32-bit MCU (Microcontroller
Unit) and 12-bit ADC (Analog-to-Digital Converter) industrial
science, these powerhouses dominate the servo arena.
Their potent combination of wide voltage capabilities, high
resolution, rapid response, and patented Smart Sense
technology brings maximum performance to all radio
Members of this particular D-Series group are all
designed with extremely durable titanium gears; the
D941TW, D946TW, and D951TW trio boast full metal
cases. Pricing is $157.99.

2,048 Microstep Resolution with
New Cost-Effective Compact
Stepper Motor Controller
PI(Physik Instrumente) has released a higher
performance model of its Mercury
stepper motion controller. Stepper
motors take up discrete positions
in a revolution of a constant
distance. Typical commercial
models provide 200 to 1,000 full
steps per revolution. Designed to
deliver more than 2,000 times the
basic motor resolution, the C-
663.12 Mercury controller is the
newest addition to PI’s suite of motion control solutions.
PI’s compact C-663.12 motion controller is designed for
two-phase stepper motors in open-loop or closed-loop
operation commanded by USB or RS-232. Up to 16 units
can be combined via daisy chain to operate multi-axis
The Mercury controller includes a 48V wide range input
power supply, and all cables required for operation.
Programmable digital and analog I/O lines and input lines
for limit and reference point switches controlled via TTL
signals are also integrated.
The C-663.12 is equipped with a data recorder for high
speed tracing, ID chip compatibility for quick start-up and
on-the-fly parameter changes, and
exchange of system components
without recalibration. The controllers
are delivered with extensive software
packages, including drivers for
LabVIEW as well as dynamic libraries
for Windows and Linux.
Piezo Linear Motor
PIalso introduces a new robust OEM walking motor drive —
the N-331 — with its configuration rooted in existing
patented piezo actuator technology and a patented piezo
stepping motion principle design. Based on the application
of historically successful technology, the new design is ideal
for use in high-end applications that require extreme
precision and durability.
Unlike traditional electromagnetic motors, piezo motors
do not create magnetic fields, nor are they influenced by
magnetic or electric fields — a characteristic that is
