GEANERAL INFORMATION 
Power

The nominal output of the engine is determined under the following conditions:
   • rated voltage, shown in plate tolerance ± 5% 

• Frequency of supply voltage tolerance ± 1%
   • ambient temperature - 40 ° C
   • altitude up to 1000m
   • mode in S1 continuous EN 60034 -1

In deviation from these conditions limit output of the engine is determined by the formula:

     Pd = kt.kh.Pn

Torque

Bearings
All motors are manufactured with single-row ball bearings, double sealed with a reduced level of vibration - see Table 3.

Degree of protection
The degree of protection of electric motors is IP54 or IP55 according to IEC 60034-5

When ordering motors they are made with  a second output shaft end

Thermal class of insulation - F (155 ° C)

Standard

Three-phase asynchronous motors
AT series is produced by the height of the axis of rotation - 71 ÷ 180mm.
Single-phase asynchronous motors
Height of the axis of rotation - 71 ÷ 100mm.
Produced series:
   • ASR - engines with starting and running capacitor
   • AS - motors with starting capacitor
   • AR - engines running capacitor

Electric motors are short-circuited rotor and external fan blowing its own - a system of cooling IC41, according to EN 60034-6

Electric height of the axis of rotation 80 ÷ 132mm are available:
  • aluminum body and aluminum shields
  • aluminum body and cast iron shields
  • cast iron body and iron shields
Electric height of the axis of rotation 160 ÷ 180mm are available with cast iron body and iron shields.
Terminal box is located above the body. There is a possibility to rotate the findings of the terminal box of three-phase motors of 90 °. In single-phase motor terminal box terminals are towards the fan.
Terminal box is made of aluminum alloy. Short circuited rotors with aluminum coil with high conductivity. The shaft is directly stamped into the rotor assembly by ensuring the provision of several engine torque. The axial clearance of the rotor is offset by equalizing spring washers.
The fan casing is made of sheet steel. The fan is made of plastic.
Windings of the motor are made of enameled copper wire.
Starting capacitor single-phase motors of series ASR and AS off with a centrifugal switch.
