What are the 2 Pole Motors?

2 Pole Motors work on the principle of electromagnetism. The device works smoothly by keeping its internal environment cool and protecting the device from overheating. The device is more durable, easy to manage, and high life of bearing. The insertion of carbon steel in the body of the machine makes it resistive to decay. The body shows the IP54, IP55, IP65, and IP66 protection levels and shows a wide range of applications. The body shape is cylindrical which makes it efficient in its working.

For the accurate rotation of the motor, the rotor is present in the device. High productive rate, presence of premium quality components, and environment friendly make the motor successful in all chemical industries and mills. It has also shown its works in the best way in conveyers and industries.

Construction and Structure

Construction of 2 Pole Motor

2 pole motor is equally important in outdoor and indoor applications. Due to this, its construction is done according to the purpose of use. Some basic entities of 2 pole motor are briefly described here:

The Bearing System:

YE2, YVFE2, YBX3, YE3, and various other series of motors are manufactured by this brand. They have a ball bearing system that can be permanently sealed or re-greaseable. While the floating bearings of FS80 to FS160 are joined together.

It keeps a certain distance between rotor and stator while providing support to the moving items.

Grease Life and Re-Greasing Interval:

Generally, the grease life is of bearing’s lifetime. The lifetime of a bearing is equated with bearing grease, especially for permanent lubrication. It is possible only if the product is constructed by keeping in view the specifications of that particular motor.

However, for those motors which are re-greased, their lifetime can be extended by lubrication. In this way, some unavoidable factors (temperature, mounting operational conditions, speed, bearing size, and load amount) can be controlled.

If the motor is running at more than its rated speed, the motor will begin to vibrate. It will exert more radial and axial force on the bearing. Due to this, the overall lifetime of the bearing will be lowered.

Some environmental factors also affect the normal vibration of the motor, which again affect the bearing resulting in the reduced lifetime of the bearing.

Similarly, an increase in temperature also affects the lifetime and re-greasing interval as well.


The rotor is the moving element of the motor which is made up of metallic components. The armature acts as a permanent magnet that helps in generating the alternating current. These rotors are dynamically stabilized using a half key.

Anti-Condensation Heater:

Sometimes the environment can cause the condensation of the windings like inactivity of the 2 pole motor in wet conditions or raised temperatures can be controlled with these anti-condensation heaters.

When the motor is working, the anti-condensation heaters must be powered OFF and after its operation, the heaters are turned ON.

Rated Output:

When the YE2 series motor run under ambient conditions (-15oC to 40oC and an altitude of 1000m at sea level) the rated output is obtained.

Voltage and Frequency:

All the 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 ±10% and +3% / -5%. The temperature of category A motors is 10K higher than category B.

Features of 2 pole motor

YE2, YVFE2, YBX3, YE3, and other series of motors have more advanced features. Some of them are described here:

  • The lifetime for permanent lubrication is 20000 hours.
  • While the lifetime for re-greaseable bearings is 4000 hours.
  • The lifetime of bearings’ grease decreases to one-half only if the coolant temperature (CT) is enhanced by 10K.
  • The power of the anti-condensation heater of FS80 to FS355 ranges from 20W to 100W.
  • The potential difference between FS80 to FS355 is 220V.
  • The frame of the motor is composed of cast iron.
  • It has a vertical-horizontal radiator structure.
  • The 2-pole motor has a beautiful appearance with good mechanical strength.
  • The small sheets inside the motor are made of high-quality silicon sheets.
  • The stator and rotor contain an iron core.
  • The electromagnetic wire is highly insulated.
  • The stator with winding is VPI coated which improves its electrical properties.
  • For ventilation, the structure of the motor is divided into internal and external air paths.
  • Inner heat is moved towards the inner heat dissipation path through the internal fan and rotor air blade.
  • The external heat remover dissipates the heat on the base shell to maintain the internal temperature.
  • The rotor is made of aluminum or copper.
  • 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 2-pole motor is 3000 while at 60Hz it is 3600.
  • This external fan also minimizes the ventilation noise.
