Construction of 8 Pole Motor

Longbank manufactures different types of IEC low voltage motors which belong to YE2, YVFE2, YBX3, YE3, and various other series of motors. The 8-pole motor is constructed by following all the specifications. It consists of various components. Any change in its parts can lower the efficiency of the motor. Some of these are explained briefly here:

The Bearing System:

The bearing system of the 8-pole motor is categorized into temporary and permanent greasing. Permanent greasing has the fixed lifetime of the bearing system and so that of the motor. In some IEC low voltage motors, the floating bearings of FS80 to FS160 are joined together.

Bearings are beneficial for maintaining a certain distance between rotor and stator while providing support to the moving items.

Grease Life and Re-Greasing Interval:

If you want a better lifetime of the bearing you must focus on the types of lubricants. Both these components are directly related to each other. In the case of temporary greasing, the lifetime can be increased by frequent lubrication of bearings.

It shows that the lifetime of the bearing is under the control of a person. The following factors and conditions can disturb the smooth functioning of the 8-pole motor:

  • Temperature
  • Mounting operational conditions
  • Speed
  • Bearing size
  • Load amount

Similarly, the vibration of the motor can be controlled by adjusting the rated speed of the 8-pole motor. If the speed of the motor is high, it will exert more radial and axial force on the bearing system. Which results in decreasing the lifetime of the bearing.

The maintenance and re-greasing intervals of the 8-pole motor are also affected by the hot and cold environment.


The rotating part of the motor is known as the armature or rotor. When the current from the external circuit passes through it, the poles are generated which act as permanent magnets due to metals in the structure. The half key can dynamically stabilize the rotors.

Anti-Condensation Heater:

The condensation of windings of the stator can be prevented by installing some anti-condensation heaters. So, all the 8-pole motors contain these heaters. The 8-pole motor and these anti-condensation heaters perform their actions alternately.

The absence of such heaters can damage the winding of the motor resulting in decreasing the motor’s productivity.

Rated Output:

The 8-pole motor belongs to the IE2 low voltage series motor. All the 8-pole motors yield the best results which are termed as their rated output. The optimum conditions for achieving the rated output of the 8-pole motor are temperature (-15oC to 40oC) and its altitude from sea level which should be 1000m.

Voltage and Frequency:

The 8-pole motors of categories A and B are IEC60034-1 verified. The voltage and frequency fluctuations of category A are ±5 % and ±2% respectively. Similarly, the voltage and frequency fluctuations of category B are ±8% and +3% / -5% respectively. The temperature of category A motors is 8K higher than category B.


Some of the most appropriate features of the 8-pole motor belonging to the YE2, YVFE2, YBX3, and YE3 series of motors have more advanced features. Some of the specifications of these series are described here:

  • More than 20,000 hours is the lifetime of the permanent lubrication in the bearing system.
  • While the lifetime for re-greaseable bearings is more than 40000 hours.
  • As the temperature of the 8-pole is increased by 8K, the lifetime of the bearing is reduced by one-half.
  • The power of the anti-condensation heater of FS80 to FS355 ranges from 725kW to 745kW.
  • The potential difference of the 8-pole motor is 220V to 660V.
  • The frame of the motor is very strong due to cast iron.
  • It has a vertical-horizontal radiator structure.
  • The 8-pole motor has an amazing outlook with better mechanical strength.
  • The small sheets inside the motor are made of high-quality silicone sheets to reduce energy losses.
  • The stator and rotor contain an iron core that acts as a permanent magnet.
  • The electromagnetic wire is highly insulated.
  • The electrical properties of the stator’s windings are improved by VPI coating.
  • For ventilation, the structure of the motor is divided into internal and external air paths.
  • Inner heat is forwarded towards the inner heat removing path through the internal fan and rotor air blade.
  • When the external heat remover dissipates the heat on the base shell the internal temperature is maintained.
  • Rotor contains aluminum or copper for generating permanent poles.
  • The air gap is calculated by the G1.0 level.
  • The axial motion of the fan in the external fan is maintained to effectively dissipate the heat.
  • At 50Hz the rpm of the 8-pole motor is 750 while at 60Hz it is 900.
  • This external fan also minimizes the ventilation noise.
  • Its percentage efficiency ranges from 78.2% to 94.5%.
  • The power factor of an 8-pole motor is in the range of 0.71 to 0.83 depending upon the type of the motor.
  • The body weight of an 8-pole motor ranges from 51kg to 2190kg.
