2. BASIC DESIGNATION OF MOTORS IN THE PRODUCT RANGE
Each motor in the product range is supplied with nameplate where is the basic information about the
product and rated electrical data.
Basic name plate
The following data is stated on the nameplate:
Code
:
Motor code number used for identification during the production process, and as a
reference for ordering spare parts for the motor in the maintenance process.
N
0
:
Serial motor number combined with the date of production
~
:
Number of motor phases( 1- single phase, 3 – three phase)
Type
:
Motor type designation mark according to the explanation from the introductory part of this
instructions combined with mounting arrangement (B3, B5, B14…)
V, Hz
:
Voltage and frequency of the power supply for which the motor is built, and where motor
generates rated characteristics when under rated loaded stated in kW column
A, min
-1
,cos
φ
: rated characteristics generated by the motor when under rated loaded stated
To
:
Environment temperature for which the motor is built, and at which it can be loaded with
rated power.
Cl
:
Insulation system used in the motor (F- the highest allowed temperature 155°C, H-180°C)
IP
:
Index of protection achieved by housing and bearing shields design with regard to the
harmful influence of water and dust.
S
:
Type of duty regime for which the motor is built (S1 – S10)
The last line of the name plate contains information on installed auxiliary equipment.
•
For motors with breaks – information about rated brake torque and voltage.
•
For EX motors - information about installed protective elements (PTC..).
•
For motors with winding heaters - information power and voltage of heaters.
Basic name plate for multi
voltage area
For motors equipped with nameplate for multi voltage area or ones used for Ex db (eb) controlled via
rotational speed regulator (duty regime S9), information about rotational velocity and belonging rated
characteristics is entered.
On such nameplates additional information can be found:
- IC:
type of cooling (IC411 – own ventilation, IC 410 – without ventilation…)
- Rise: information about declared heating of the motor at rated conditions (B – 80K, F – 105K
at the environment temperature of 40°C
- DE/NDE:
information about installed bearing type
