Introduction
General technical specifications
Geared motors for use worldwide
1
■
Without CE marking for export
For geared motors to be exported outside the European
Economic Area, the order option "without CE marking for export"
is available. The CE marking is not displayed on the rating plate
of these motors.
These geared motors may only be exported to countries outside
the European Economic Area which do not require the
CE marking.
■
Motors for the North American market
Motors in frame sizes 63 to 132 are available in designs which
meet the UL-R and CSA standards.
Note:
In the USA, a distinction is made between the rated voltage of
the supply system and the rated voltage of the motor.
See the table below for the assignment:
UL-R – Underwriters Laboratories Inc.
The motors are listed for up to 600 V by Underwriters
Laboratories Inc. ("Recognition Mark" = R/C). Motor voltages up
to 600 V are certified according to UL. "UL Recognition Mark" is
included on the rating plate of the motor.
In addition, the motor is designed to meet the NEMA MG1-12
electrical standard and includes the following data on the rating
plate:
•
Rated voltage(s)
•
Nominal efficiency
•
Design letter
•
Code letter
• CONT
•
NEMA MG1-12.
Externally or internally mounted components such as:
•
Motor protection
•
Heating element
•
Forced ventilation
• Brake
• Encoder
•
Plug connection
are UL-R/C, CSA, or C-US listed or used by manufacturers in
accordance with regulations. UL-R/C cable glands must be
used for the cable entry.
CSA – Canadian Standard Association
The motors are approved for up to 690 V in accordance with the
"Canadian Standard Association" (CSA). Externally or internally
mounted components which are used are listed by CSA or are
used by manufacturers in accordance with regulations. The CSA
mark and the rated voltage are stamped on the rating plate.
When energy-saving motors are ordered, they also have the
"CSA-E mark" on the rating plate.
■
Motors for the Chinese market
CCC-certified motors, frame sizes 63 to 90, are available for
export to China.
The "China Energy Label" required for import into China is
available for motors in frame sizes from 80 to 132.
The motors are marked according to the requirements with CCC,
CEL or both specifications.
CCC – China Compulsory Certification
"Small power motors" which are exported to China must be
certified up to a rated power of:
2-pole:
2.2 kW
4-pole:
1.1 kW
6-pole:
0.75 kW
8-pole:
0.55 kW
Motors requiring certification
are certified by CQC
(China Quality Certification Center).
When ordered, the "CCC (Safety Mark)" logo is stamped on the
rating plate and packaging.
Note:
Chinese customs checks the need for certification of imported
products by means of the commodity code.
The following do not need to be certified:
•
Motors imported to China which have already been installed
in a machine
•
Repair parts
CEL – China Energy Label
China introduced mandatory energy efficiency labeling for
electric motors in June 2008.
From September 1, 2008, and until the transition phase expires,
the affected electric motors may only be imported into China and
sold in the country with a valid "China Energy Label".
The motor must be labeled with the "China Energy Label" sticker,
which states the efficiency class.
In addition to the Energy Label (dimensions 80 x 54 mm), the
efficiency is also stamped on the rating plate.
2-pole, 4-pole and 6-pole motors with a line frequency of 50 Hz
and a rated voltage of up to 1 000 V must be appropriately
marked. Efficiency classes 2 and 3 apply here to motors with
rated powers from 0.75 to 375 kW.
■
Motors for the Eurasian market
SIMOGEAR geared motors are certified for the Eurasian
Economic Area.
In the Russia, Kasachstan and Belarus customs union, new
technical regulations and uniform conformity requirements
(EAC) have been introduced. These replace the previous
GOST-R certificates which thus lose their validity.
The certificate is mandatory for export and is required by the
customs authorities.
The EAC certificate is valid for all geared motors. For gearboxes
with adapters, the EAC certificate is not necessary because the
EAC certificate only refers to the motor.
