What is the 16.8kv Motor?

16.8kv device is a high voltage motor that shows the rotation according to the presence of magnetic poles in the voltage range of 16800V. The machine’s body contains alternative magnetic poles in both the north and south directions and the rectified diode of 4.7A. The cylindrical body of the machine includes the hard lamination of copper or iron that protect the device from climate.

The presence of the device’s rotor makes the precise rotation of 16.8kv. Many other incomparable features are present in the device, such as easy to manage, most resistive body material, and no noise during working that you can install anywhere.

Construction of 16.8kV Motor

16.8kV motor encloses several components which play a significant role in its operation. Each part is vital for determining the productivity of a 16.8kV engine. Some of its modules are written here:

The Bearing System:

Longbank has created several articles for the welfare of people globally. Almost all the products of Longbank belong to YXKK, Y, YKS, YKK, YPTKK, and YPTKS motor series. The bearing system of these motors can be classified into sealed or re-greaseable bearings.

Some 16.8kV motors have unconfined bearings belonging to various motor categories. These bearings hold a certain distance between the rotor and the stator while supporting the moving load.


The installation of a 16.8kV motor is relatively easy because of the box-shaped frame. The appearance of the motor polishes the structure of the 16.8kV motor. Longbank presents multiple, multiple motors with variable speeds and so outputs.


The material used in the 16.8kV motor is 99% copper, which can be magnetized. Copper enhances the lifespan and quality of the motor. Each motor contains insulation systems along with windings which are folded by hand. Windings strengthen the output of the motor to a great extent.


The rotor’s core comprises silicon and aluminum, improving the motor’s quality. Several motors contain copper instead of aluminum to yield more output and balance aluminum usage.

Grease Life and Re-Greasing Interval:

The grease type regulates the lifetime of the bearing. The smearing of the motor with oil can be permanent or temporary. In permanent lubrication, the period of the bearing depends upon the oil. It depends upon its operating conditions.

In the case of repeated oiling, the period of the bearing system is expanded by using oils. This lubrication is helpful for motors that face changing conditions like temperature, speed, size of bearings, mechanical load, and operating conditions. Different aspects control the period of the bearing. One of them is the optimum speed of the motor.

Some exterior conditions like temperature can disturb the bearing’s constant functioning, resulting in its condensed efficiency. While assembling a 16.8kV motor, these dynamics are kept in view to lessen energy losses.


The motion in the motor is because of the armature. This armature contains a metallic element that acts as a permanent magnet during the passage of alternating current. Half-key maintains the rotors dynamically. Over a specific limit, the vibration will begin to press the bearings radially and axially.

Anti-condensation heater:

The main reason behind installing anti-condensation heaters in a 16.8kV motor is to maintain the standard temperature of the engine. It is relatively essential in summer as well as in cold weather conditions. These heaters operate when the motor stops working so that the ordinary temperature inside the engine can be attained.

Structural Features

The primary series of motors include YXKK, Y, YKS, YKK, YPTKK, and YPTKS, which are highly useful in multiple activities. It is just because of the innovative specifications of its parts. Some of its remarkable features are described here:

  • The lifetime of the bearings in perpetual lubrication is 20,000 hours.
  • The lifetime for re-greaseable bearings is considerably more than 40,000 hours.
  • When the CT is expanded by 10K, the bearing’s lifespan is lessened by one-half.
  • The anti-condensation heater has a power of several watts ranging from 200 to 9000kW.
  • The potential difference is 16.8kV.
  • The robust frame of this motor is due to body material.
  • It has a vertical-horizontal radiator structure.
  • The 16.8kV motor has a fantastic outlook with good mechanical strength.
  • Laminations are inside the motor, which minimizes the motor’s energy losses.
  • The stator and armature contain an iron core that tempts magnetism.
  • The protected wire is highly insulated, preventing damage to other motor components.
  • The winding with VPI (vacuum pressure impregnation) coating enhances electrical properties.
  • For aeration, the structure of the motor is categorized into inner and outer air paths.
  • Internal heat is moved towards the inner heat removal path through the internal fan and rotor air blade.
  • The exterior fan controls the internal temperature by removing the heat on the base shell.
  • Aluminum or copper can be used in place of iron in the stator and rotor to magnetize it.
  • 0 technique helps determine the distance between the rotor and the stator.
  • The distance between the winding and the rotor is measured by the G1.0 method.
  • The axial rotation of the fan in the outer fan is sustained to dissipate the heat progressively.
  • 8kV motor possesses different outputs with varying speeds, depending on the motor’s poles and frequency.
  • The outer fan can also diminish the aeration noise.
