BRUSHLESS MOTOR BENEFITS

POWERTEC Industrial Corporation manufac-
tures Brushless DC motors and controls for the indus-
trial environment. Other manufacturers produce
brushless DC motors for some specialized applica-
tions, but only POWERTEC makes a full line of
Brushless DC motors and controls from fractional to
600 Horsepower for use on industrial power sources
(230, 380, and 460 VAC three phase) in standard
NEMA (National Electrical Manufacturers Associa-
tion) frame sizes at prices competitive with conven-
tional DC and Adjustable Frequeny AC, including
vector.
Some important benefits of using POWERTEC
Brushless DC motors and controls are:
ABSOLUTE SPEED CONTROL REGARD-
LESS OF LOAD -- The speed regulation of the
POWERTEC Brushless DC motor and control system
is 0%! The speed of the motor does not change from no
load to full load. Options include a speed accuracy of
50 PPM (parts per million) and absolute ratio control.
INCREDIBLY HIGH EFFICIENCY -- The
efficiency of the POWERTEC Brushless DC motor
and control exceeds that of either conventional DC or
induction AC motors and inverters. The Brushless DC
motors are often in smaller frames than comparable
motors. This efficiency contributes to low cooling costs
for rooms where Brushless DC motors are installed as
well.
VERY LOW MAINTENANCE -- The POW-
ERTEC Brushless DC motor is as rugged and reliable
as the AC induction motor. There are no brushes to
change, no fields to burn up, and no commutator to be
maintained. The bearings are long-life bearings, ca-
pable of years of operation with only regular lubrica-
tion.
ABSOLUTE TRACKING -- Two motors can be
set up to track pulse for pulse. Their shafts will be very
nearly synchronized. This capability is standard. Op-
tions include the ability to operate at an absolute ratio
from 0.0001 to 7.9999.
The POWERTEC Brushless DC motor and control
provide performance in their standard configura-
tion which exceeds the performance of other types of
motors and controls. Even when the other types of
motors and controls are combined with expensive
added cost options, they do not perform as well as the
Brushless DC motor and control do right out of the
box.

HOW TO USE THIS MANUAL

This manual is arranged into sections covering all of
the stages of using the Model 2000C and 3000C:
1.0 Orientation to product.
2.0 Specification
3.0 Installation/Layout
4.0 Wiring/Design
5.0 Startup
6.0 Troubleshooting
7.0 Maintenance
8.0 Performance options
Reading of the entire manual will assist in under-
standing of Brushless DC motors and controls. While there
are no schematic diagrams of the boards used in the Model
2000C and 3000C in this manual, there are plenty of block
diagrams and simplified diagrams which will help the
person using this manual to observe and understand what
is going on, and to isolate problems to the board level, if
and when they should occur.
If any questions about this manual arise, contact
your distributor, representative, or POWERTEC directly.
