PROTECTION DEGREE The three-phase and single-phase electric motors have protection degrees IP44, and IP54 IP55 according to the international standard norms of DIN/VDE 0530, IEC 34-5.

DESIGN The electric motor body is longitudinally ribbed, it is cooled outside by means of an in-built fan for surface cooling

ELECTRIC MOTOR BODY The electric motor bodies are made of: Aluminum alloy of high mechanical resistance: Sizes 56, 63,71and 80. Aluminum alloy or cast iron: Sizes 90,100 and 112 Cast iron: from size132 to size 355.

THE BEARING SHIELDS are made of the same material as that of the bodies of the respective sizes of

electric motors, pointed above.

THE FAN are made of plastics or aluminum alloy

THE FAN COVERS are made of sheet steel.

THE TERMINAL BOX is located on top and is rotable at every 90°C , the terminal box of the electric motors

from size 90 to 355 , with bodies made of cast iron , can be installed on the right or the left side of the body.

THE ELECTRIC MOTORS WINDING is made of enameled copper wire.

The rotor axial clearance is compensated by a spring washer.

DRIVING END OF THE SHAFT

The motors are usually made with a cylindrical end of the shaft with internal thread, according to DIN 748, IEC 72.

The overall sizes are recapitulated in below table:

TYPE OF EXUCUTION

Depending on the way of mounting, the electric motors meet the requirements of the international standard norms

of IEC 72, DIN 42673 for form B3 and IEC 72, DIN 42677 for forms B5 and B14.

SUPPLY VOLTAGE AND FREQUENCY The electric motors are designed for normal voltage:

220V/380V for single-phase motors

220V/380V – connection ∆ / Υ for three-phase motors at 50HZ.

The admissible rated voltage deviation is ± 5%

And the admissible frequency deviation ± 1% .

TORQUE The torque of the shaft driving end of the electric motors in N.m can be calculated according to the formula:

M= 9.55P 1000/ n

P – Rated power in kw

N – Revolution per minute /RPM/.

INSULATION Our manufactured electric motors have insulation class B, F or H.

OPERATING CONDITIONS The electric motors are designed for continuous operation at duty S1 under normal climatic conditions « N », at

temperature to +40°C and altitude up 1000.

The electric motors can be manufactured for operating under tropical climatic conditions « T », as well as for other

operation cycles different from S1.
