Threephase and singlephase motor series complying with UL 1004 and
CSA. C 22.2
No 100.95 for UL and c-UL respectively, are also available for our
standard production range.

INSULATION CLASSIFICATION
Our standard motors have insulation class F while the temperature
rise is for class B. It means no longer life of motors.
Under specified measuring conditions in accordance with IEC 60034-1
standard, insulation class F for an electric
motor means that at ambient temperature of 40°C the temperature rise
is of its windings may be max. 105°C
with the additional temperature margin of 10°C.
On customer's demand, we are able to make motors insultion class
F with temperature rise for class F.
|
DEGREE O PROTECTION
According to IEC 60034-5 standard, electric motors are provided with
IP code which determines the degree of protection ensured by the housing
against access to dangerous parts, introducing foreign matter and/or
matter.
Our motors comply with IP55 protection class as standard.
| X |
Protection from introduction of solid
foreign matter |
Y |
Protection against penetration of
water and its harmful effects |
IP XY |
| 5 |
Protection against with
live or moving parts inside the enclosure. Ingress of dust is
not totally prevented, but dust does not enter in sufficient
quantity to infere with satisfactory operation of the motor |
4 |
Water splashed against the motor
from any direction will have no harmful effect. |
IP 54 |
| 5 |
Water projected by a nozzle against
the motor from any direction will have no harmful effect. |
IP 55 |
|
VIBRATION / BALANCING
All rotors are balanced dynamically with half key and this is indicated
on the rating plate with letter H.
In accordance to IEC 60034-14, vibration level A is guaranteed
for the standard motors. On customer demand,
motors with reduced vibration level may also be produced.

TOLERANCES
According to IEC 60034-1, catalogue values are permitted to deviate
from the real values as follows:
| Speed (n) |
D n = ± 20% (nS-nN) for PN > 1
kW |
| D n = ± 30% (nS-nN) for PN £ 1 kW |
| Efficiency (h) |
D h = -15% (100- hN) for PN £ 50
kW |
| D h = -10% (100- hN) for PN >
50 kW |
Power factor (cos j)
|
D cos j = -1/6 (1- cos j) |
| Locked Rotor Current (IL/IN) |
D (IL/IN) = +20% (IL/IN) |
| Locked Rotor Torque (ML/MN) |
min. (ML/MN) = -15% (ML/MN) |
| max.( ML/MN) = +25% (ML/MN) |
| Breakdown Torque (MK/MN) |
D (MK/MN) = - 10% (MK/MN)
|
| Pull-up Torque (MP/MN) |
D (MP/MN) = -15% (MP/MN) |
| Moment of Inertia (J) [kgm2] |
D J = ± 10% J |
| Sound Pressure Level (LPA) [dB] |
D LPA = +3 dB (A) |
