Construction of 10.5kV Motor

10.5kV motor is one of the most innovative ideas of Longbank. This motor needs high input voltage to accomplish the task of heavy-loaded objects. Longbank offers several series (YXKK, Y, YKS, YKK, YPTKK, and YPTKS) of motors that present various models with only a few varying properties.

All the models of 10.5kV have some common elements that control the overall productivity of the motor. These elements are discussed here briefly:


The robust box-shaped frame makes the 10.5kV motor highly adjustable and convenient for installation. You can ask Longbank’s team to manufacture your desired structure for the particular engine.


The material makes the motor highly durable, enhancing productivity and the engine’s quality. Usually, copper comprises 99% of the stator. Significant installation and many other vital systems help the motor to achieve the results.


Aluminum casting along with silicon core improves the quality and efficiency of the motor to a great extent. However, several engines contain copper casting. The motor winding is usually done without machines to ensure a better connection and achieve sound output.

The Bearing System:

The bearing system of 10.5kV is highly efficient in maintaining the productivity of the motor. The bearings of this motor can be confined or free to move depending upon the model type. The freely rotating directions are usually found in FS80 to FS160 motors. These bearings play a significant role in maintaining the air space between the rotor and the stator and sustaining the load.

Grease Life and Re-Greasing Interval:

Grease imparts a crucial role in controlling the motor’s efficiency. A little deviation in oil disturbs the motor’s productivity. Sealed motor bearings have a lesser period than re-greaseable motors. Frequent oiling improves the lifetime of the motor by many times.

Similarly, several other factors play a vital role in sustaining the motor’s effectiveness, including temperature, operating conditions, motor speed, the size of bearings, and the amount of load. A hot and cold environment can cut the smooth functioning of the motor.

  • The bearing’s lifetime is reduced at high temperatures.
  • Any variation in mounting conditions can disturb the smooth activity of the 10.5kV motor.
  • Over-weighted motors can also reduce the motor’s efficiency.
  • The bearing’s size can also hinder the motor from achieving the enhanced yield.
  • Over-speed of the motor can lessen the efficiency instead of increasing it.


The toing and froing of the rotor generate vibration. This rotor contains several small sheets of metal known as laminations that act as magnets after the passing of alternating current. Half-key method stabilizes the rotors dynamically. The enhanced speed over a specific limit will pressurize the bearings axially and radially, resulting in declined efficiency.

Anti-Condensation Heater:

In primitive motors, the increased temperature of the surrounding cause the condensation of the motor’s windings resulting in the decreased efficiency of the motor. But now, Longbank has fixed this difficulty by installing anti-condensation heaters inside the motor. These heaters initiate their work after the completion of motor functions.
