This information is provided by Alcatel Dunkermotoren, Bonndorf, Germany
in November 2005 for the SPS/IPC/Drives Exhibition in Nuremburg
Field of Application for Proven Drives Substantially Extended
Digital control for 4-quadrant drives integrated into DC commutator motor
Dunkermotoren in Bonndorf combines, for the
first time, the advantages of cost-effective DC
commutator motors with comprehensive digital
electronic regulation and control. At the
SPS/IPC/Drives Exhibition in Nuremburg this
company presents Variant SI of its GR53 and
GR63 motors. These motors have digital
control electronics for 4-quadrant drives built
in. The electronic functionalities are provided
by Dunkermotoren as firmware in the Motor. In
this way, precise speed control can be achieved
with a minimum of wiring. As standard, the
speed target input is provided by an analogue
voltage in the range 0 to +10 V. Two digital
input signals determine whether rotation is to be
clockwise or anti-clockwise, can block the
controller, and stop the motor with a holding
moment. At a digital output, information is
available about faults in the motor or
electronics. In addition, there is an output which
provides 16 impulses per revolution of the
motor. An output signal for the direction of
rotation is available as an option. For example,
this permits monitored positioning of these
compact DC motors with a minimum of
external circuitry. To help match motions to
local conditions, in particular when positioning,
two different speeds and their associated
acceleration and braking ramps can be
memorised. These can be specified using

Teach-In. Thus the GR53SI and GR63SI DC
motors combine the advantages of conventional
DC motors – compactness, high power density,
and robust design – with those of modern
digital control and regulation technology. Users
in industrial and building automation, in
medical technology, and manufacturers of
packaging and filling plant can profit from
these drives. In such applications, DC motors
with conventional commutators and brushes
have proved themselves millions of times and
over many years thanks to their robust
mechanical and electrical properties and
maintenance-free operation.
The DC motor GR53SI has an output of 40 W
or 60 W at nominal voltages from 12 to 40 V,
and the output of the GR63SI DC motor is 50
W or 100 W. Depending on the version,
nominal torque is up to 17 Ncm for the
GR53SI, and up to 29 Ncm for the GR63SI.
The starting torque achieved is up to 140 Ncm
or 210 Ncm respectively. Of course, like all the
other DC motors from Bonndorf, these DC
Motors with Integral Electronics can be
combined with a wide range of planetary and
worm gears, encoders and brakes from this
manufacturer's well-proven modular system. In
this way, complete drive packages can be
created which are precisely tuned to a particular
application and, at the same time, cost-effective
and readily available. On request, where the
quantities are adequate, this manufacturer from
the Black Forest will develop customer-specific
firmware versions and mechanical
modifications.

Advantages combined: These cost-effective DC motors
with commutators and brushes now have integral control
electronics for 4-quadrant drives so that, with a minimum
of external wiring and programming, complex motion
profiles can be achieved. In addition, they are robust
enough to withstand mechanical and electrical overloads.
