ROHNERT PARK, CA – Parker’s
Electromechanical Automation Division announces the release of its MPN
series of brushless servo motors. The MPN motors are designed to
replace the now-obsolete N-Series motors recently discontinued by
Rockwell Automation/Allen-Bradley. According to Parker, the MPN offers
more torque per frame size than the existing N-Series motors.
Parker’s
MPN motors feature the proven technology of our MaxPlus motor family
and are modified to match the mechanical and electrical characteristics
of the Rockwell N-Series family. The front motor mount, shaft
dimensions, connectors and the electrical Ke (back-emf) of the motors
are identical to that of the N-series motors. Parker indicates the
motor’s inertia is usually within 10% of the N-Series, so tuning of an
existing system would be rare. One minor drawback is some of the
motors may be slightly longer than the N-Series.
“The MPN’s use
of neodymium magnets gives the MPN extremely high torque when compared
to the N-Series,” says Pat Berkner, rotary motor product manager.
“This means an existing system will benefit greatly by using the MPN
motors. Some motors’ Kt (torque constant) is twice that of the
N-Series. This means less current, less energy, and less heat generated
per a given application, yet more torque.”
MPN motors are ideal
in applications for packaging, printing, semiconductor, and machine
tool industries. “Putting the MPN in places where the N-Series was
installed is a benefit to the user. Since these motors have the same
mounting, the same connectors, and very similar electrical
characteristics, it is very easy to install an MPN. All motor
configuration files are supplied on the Internet to make it even easier
to get an MPN installed and running with minimal effort. If your
existing machine needs more torque — more throughput — put on the MPN
motors,” says Berkner.
MPN motors replace all the Rockwell
N-Series motors, including the N3406, N3412, N4214, N4220, N5630,
N5637, and N5647. All MPN motors have a 2000-line encoder, a 24 volt
brake option, and are rated for a 340 volt DC bus. The N2302 and N2304
come standard with a 1000-line encoder and are rated for 170 volts DC.
They too have an optional 24 volt brake. The MPN motors are UL and CE
rated, and are sealed to IP65 as a standard. All the MPN motor
configuration files, which contain the electrical setup parameters, are
available to the user on the parkermotion.com Web site. This means that
users simply need to upload the motor’s configuration file (.mxf) to
their existing Rockwell motor database, select that motor, and they are
ready to run.
