Construction of 6.6kV Motor

6.6kV motor is one of the high voltage motors that offer several models with varying characteristics. 6.6kV motor possesses differentiating features that attract customers worldwide. This motor owns numerous series, including YXKK, Y, YKS, YKK, YPTKK, and YPTKS. Each series offer a wide range of products.

All models of 6.6kV have some unique elements which are directly involved in maintaining the motor’s efficiency. Any disturbance to them will result in a decrease in motor productivity. A few of its components are described here:


The machine’s frame is box-shaped, which is convenient for management and installation. The phenotype of the device can also be adjusted according to the client’s needs.


The presence of 99% pure copper in the stator proves the quality of the device with maximum efficiency. A better insulation system is also present in the machine. All the windings are done by handwork by confirming the exact fitting.


The presence of aluminum casting on the device with the silicon core proves the unbeatable quality of the device. The copper rotor is also present in the rotor of many instruments. The presence of well-defined shafts also provides the capacity and efficiency of the device.

The Bearing System:

The bearing system of the 6.6kV motor can be joined or free to rotate according to the model type. On this basis, the engine can be sealed or re-greaseable. Sealed motors are lubricated once in their period, while re-greaseable motors are frequently oiled, improving the bearings’ lifetime.

The primary role of the bearing system is to adjust the distance between the rotor and the stator while supporting the moving objects. In this way, the air opening is maintained between the armature and stator to make the smooth function of the motor.

Grease Life and Re-Greasing Interval:

Different oils are used for lubricating the bearings that strongly affect the motor’s efficiency. Each model of 6.6kV motor has a different time interval for re-greasing the motor. Any variation in the composition of oil will result in a decrease in the motor’s efficiency.


The rotor of the 6.6kV motor produces minor noise with minimum vibration. Any damage to the smooth functioning of the engine will result in a loss of motor efficiency. If a motor begins to vibrate more than its optimum speed, it will exert more pressure on the radial as well as axial sides of the bearings. This process will result in the loss of the motor’s efficiency.

The half-key technique helps in controlling the speed of the motor. When AC passes through these laminations, magnetism is induced in metal sheets.

Anti-Condensation Heater:

Increasing the surrounding temperature can cause the motor’s windings to melt. This process is usually inhibited in Longbanks’ motor by fixing numerous anti-condensation heaters. These heaters are available in varying powers. The working of the engine is alternate to these heaters.

Rated Output:

Many aspects play a crucial role while calculating the rated output of the motor. These are temperature, altitude of motor, and many other elements. The temperature of the 6.6kV motor must be maintained between -15oC to 40oC while it should be installed at the height of 1000m above sea level.
