MOTORS
Voltage and Frequency
NORD motors are available in a number of voltages
and frequencies. The standard voltages are commonly
available. Optional voltages can be provided, but may
include an increase in price and additional lead time.
It also may be possible to provide motors with special
voltages and frequency operation points.
Poles / speeds
NORD offers a variety of single speed and two speed
motors in addition to the standard 4 pole motor. NORD
single speed motors are inverter/vector duty rated,
however, it is not recommended to run a NORD two
speed motor with a frequency inverter.
Motor Options & Construction
NORD motors are stocked in one of two ways. The
fi rst method is to stock a complete motor that is
ready to be assembled to a gear reducer or shipped
as a stand alone motor. The second method, the mo-
tor is assembled from component parts. The
Mod
next to a motor option designates that the option
can be added to a complete motor by simple modifi -
cation. The
Build next to a motor option indicates
that the motor will need to be built from component
parts in order to incorporate the motor option.
US Canadian Standard (CUS)
CUS motor construction defi nes that NORD motors
are constructed in accordance to UL 1004 (electric
motors) and CSA C22.2 No. 100-
04 (motors and gen-
erators) guidelines. This option is standard for 208,
230, 460, and 575 Volt operation at 60 Hz.
Motors nameplated with the CUS option will be
marked and indicating that the Underwriters
Laboratories and CSA have tested and approved
NORD motors according to both US and Canadian
standards.
