What is an 8kv motor?

Longbank manufactures the 8kv motor that is professional in energy products. The machine yields an output of 100kw to 20000kw and rotates with the speed of 3600rpm at 50Hz. Primarily applicable in mixers, cranes, conveyors, compressors, and pumps.

Construction of 8kV Motor

Diverse types of essentials are fitted inside the body of the 8kV motor. Each module plays a vital role in scheming the efficiency of the engine. However, any impairment on its part will lessen the productivity of the motor.

Longbank offers numerous high voltage motors presenting multiple models vastly precise in their role. A few sequences are YE2, YVFE2, YBX3, YE3, etc. A few crucial components of all these models are inscribed below:

The Bearing System

One of the main apparatuses of the 8kV motor is its bearings. These bearings maintain the motor’s period and are further detained by grease. These bearings can be unrestricted, or they can be articulated.

Free bearings exist in motors with a frame size of 80-160. These bearings maintain a certain distance between the rotor and the stator and provide sustenance to the weight.

Grease Life and Re-Greasing Interval

Some bearings are recurrently greased, while some are greased only once in their period. If the lubrication is done in pauses, it expands the time of the 8kV motor. Longbank offers these structures due to its dynamic team.

Countless aspects control the overall productivity of the motor and retain the motor’s functions smoothly. A few of these aspects are the temperature of the surrounding, the operating conditions, the optimum speed of the motor, the bearing’s size, the amount and weight of the load, and many others.

An increased speed over a fixed limit will press the bearings from radial and axial directions, off-putting the motor’s overall period. A scorching and cold surrounding also undermines the plane functions of the 8kV motors.


Vibration is only produced by the toing and froing of the rotor. These rotors comprise metal sheets with the magnet’s north and south poles through alternating currents. These rotors are sustained through a half-key.

Anti-Condensation Heater

Some motors are precisely planned to work in high-temperature situations. But if non-specific motors are used in such conditions, their windings commence condensing. This marvel usually happens in hot summer weather. Such problems are not found in the Longbank’s 8kV motor because of the complex addition of the anti-condensation heaters.

Rated Output

Longbank’s crew is highly proficient in the industrial of the 8kV motor. They retain in view all the stipulations of the motor. The two significant aspects for adjusting the optimum results are temperature (-15oC to 40oC) and height (1000m) above sea level.

Voltage and Frequency

Longbank presents two categories of 8kV motors that are IEC60034-1 verified. Category A’s voltage and frequency variations are ±5 % and ±2%, respectively. The fluctuation of voltage and frequency of category B are ±10% and +3% / -5%. The category’s A motors can best perform at a higher temperature than the other motors.

Features of 8kV Motor

Each motor possesses peculiar structures which depend upon the series of the motor. Some of the standard features of the 8kV motor are written here:

  • One-time lubricated motors have a lifetime of 20,000 hours.
  • Frequently lubricated motors possess a lifetime of 40,000 hours.
  • 10K increase in CT lowers the bearing’s lifetime by one-half.
  • 7kW motor is available in multiple watts and speeds.
  • The voltage of this motor is 8000V.
  • The frame of the motor is composed of cast iron, making it hard and beautiful.
  • The structure of the space heater is vertical-horizontal.
  • The motor possesses good mechanical strength.
  • Small metal sheets minimize energy losses.
  • The material inside the stator and rotor induces magnetism.
  • The filling of electromagnetic cables defends the component from any impairment.
  • VPI layering aids in refining the electrical properties of the stator’s windings.
  • Internal heat is emitted through the internal fan. At the same time, outer fans help dissipate the external heat.
  • The poles in the rotor are produced by passing the current.
  • The G1.0 level measures the air space.
  • The external fan can also reduce the motor’s noise.
