Construction and Structure

Construction of 9kV Motor

The 9kV motor comprises multiple components. The rated yield of the 9kV motor is significantly decreased by affecting its members. Some of its parts are enlisted here briefly:

The Bearing System

All the IEC high voltage motors of Longbank belong to different series having different models. These series are IE2, YVFE2, YBX3, IE3, IE4, etc. All these motors have bearing systems that can be lubricated once or frequently in the motor’s lifetime.

These bearings can be unconfined, or they can be restricted together. In contrast, the floating bearings belong to the FS80-FS160 category of motors. The significant role of these bearings is to adjust a specific air space between stator and armature while balancing its moving load.

Grease Life and Re-Greasing Interval

Grease life determines a bearing’s lifetime. Both these run side by side. Any distortion in the grease composition will severely affect the bearing’s period. Longbank’s experts manufacture the 9kV motor by following all the specifications of the 9kV motor. For greasing, different kinds of oils are available.

The time of some motors can be expanded significantly for re-greaseable. It shows that the period of the bearing can be sustained. Multiple factors affect the motor’s smooth functioning, which can dramatically alter the motor’s productivity. Herein we have defined some of these factors:

  • Temperature
  • Operating conditions
  • Speed of motor
  • Bearing size
  • Load size and weight

If the 9kV motor’s vibration is precise, you can regulate the rated speed of the motor accordingly. Otherwise, it will apply more radial and axial pressure on the bearing, reducing its lifetime. A hot and cold environment can also disturb the maintenance and re-greasing periods of the 9kV motor.


The motion of the rotor produces the tremor. When an alternating current permits through its metal sheets, magnetism is produced. These rotors are energetically maintained using a half key.

Anti-Condensation Heater

During summer weather, the temperature can cause the melting of the windings. You can resolve this issue by using anti-condensation heaters in the 9kV motor. The motor and these heaters work interchangeably.

Rated Output

If you want to get the optimum results of the 9kV motor, then you must know all the operating conditions. These conditions are temperature and height. The temperature should be maintained between -15oC to 40oC, and its altitude above sea level should not exceed 1000m.

Voltage and Frequency

The 9kV motors of classes A and B are IEC60034-1 verified. Class A’s voltage and frequency oscillations are ±5 % and ±2%, respectively. Likewise, the distinction in voltage and frequency of class B are ±10% and +3% / -5%. The temperature of class A motors is 10K higher than class B.

Features of 9kV Motor

Each motor is built according to its peculiar features, which differ according to the series. Each series presents various types of models of the 9kV motor. Some of the parts have been mentioned over here:

  • The period of a one-time oiled motor is 20,000 hours.
  • The time for re-greaseable bearings is elevated to 40,000 hours.
  • If the coolant temperature (CT) is expanded by 10K, the time of bearings’ grease is lowered by one-half.
  • The power of the anti-condensation heaters of the 9kV motor is variable.
  • The potential difference is 9000V.
  • The setting of the motor is robust due to cast iron.
  • It has a vertical-horizontal emitter structure.
  • The 9kV motor has a beautiful appearance with good mechanical power.
  • Energy losses are adjusted by installing multiple laminations.
  • The stator and rotor hold an iron core that turns into a magnet.
  • The wire is insulated to minimize the mutilation to other parts of the motor.
  • The VPI veneer enhances the electric properties of the stator’s windings.
  • For airing, the structure of the motor is separated into internal and external air routes.
  • Internal heat is moved through the internal fan and rotor air blade.
  • When the exterior heat remover removes the heat on the base shell, the internal temperature is maintained.
  • The G1.0 level calculates the air space between the stator and the rotor.
  • At different frequencies, its rpm is variable.
  • The external fan can also reduce the airing noise.
