What are the 5kv Motors?

5kv Motor is a three-phase induction motor that yields energy of 6.5 to 1000kw. Asynchronous motor represents the rotation of 1500rpm at 50Hz and 1800rpm at 60Hz. ISO certified product and applicable in conveyors, mills, pumps, mixers, compressors, fans, crushes, and cranes.

The device’s rotor makes the device’s precise and accurate rotation. The durable casing of the machine protects it from environmental effects. Anti-condensational heaters also protect it from dampness.

Construction and Structure

Construction of 5kv Motor:

5kv motor contains several components which play a significant role in its working. Each part is crucial for an ideal procedure of a 5kv engine. Some of its modules are written here:

The Bearing System:

Longbank creates several items for the ease of people. Its products include IE2, IE3, YVFE2, and the YBX3 series. The bearing system of these products can be categorized into sealed or re-greaseable bearings.

Some products have unconfined bearings that belong to the FS80 to FS160 motors which are classified according to the frame size. These bearings keep a certain distance between the rotor and the stator while supporting the rotating parts.

Grease Life and Re-Greasing Interval:

The type of grease determines the lifetime of the bearing. The oiling of the motor can be permanent or temporary. In permanent lubrication, the lifetime of the approach depends upon the grease. It depends upon its manufacturing conditions.

In the case of frequent oiling, the lifetime of the bearing system is improved by using oils. This lubrication is helpful for motors that face fluctuating conditions like temperature, speed, bearing size, mechanical load, and operating conditions.

Different factors control the lifespan of the bearing. One of them is the rated speed of the motor. A rise in the motor’s speed will commence vibrating, ultimately causing more radial and axial force on the bearings.

Some external conditions like temperature can affect the bearing’s smooth functioning, resulting in reduced efficiency. While fabricating a 5kV motor, these factors are kept in mind to minimize energy losses.


Movement in the motor is because of the rotor. The other name of the rotor is the armature. It contains a metallic part that acts as a permanent magnet. It helps in producing the alternating current. Half-key maintains the rotors dynamically.

Anti-condensation heater:

The main reason behind the fixation of anti-condensation heaters in a 5kV motor is to sustain the standard temperature of the engine. It is pretty crucial in hot as well as cold weather conditions. These heaters are turned ON when the motor stops working so that the average temperature inside the engine can be attained.

Rated Output:

The optimum yield is achieved as a result of maintaining the operating conditions of the 5kV motor. The standard requirements for this motor are temperature (-15oC to 40oC) and the altitude (1000m) from sea level.

Voltage and Frequency:

5kV motors belong to two categories which are category A and category B. the voltage and frequency are adjusted in a narrow range of ±5 % and ±2%, respectively. While, the voltage and frequency of category B can vary by ±10% and +3% / -5% respectively. Category A has a 10K higher temperature than category B.

Structural Features:

IE2, YVFE2, YBX3, IE3, and other series of motors are highly effective in several functions. It is just because of the novel features of its parts. Some of its peculiar qualities are described here:

  • The lifetime of the bearings in permanent lubrication is 20,000 hours.
  • The period for re-greaseable approaches is slightly more than 40,000 hours.
  • When the CT is enhanced by 10K, the bearing’s period is reduced by one-half.
  • The anti-condensation heater has a power range of several watts.
  • The potential difference is 5kV.
  • The sturdy frame of this motor is due to cast iron.
  • It has a vertical-horizontal radiator structure.
  • The 5000V motor has a beautiful outlook with good mechanical strength.
  • Laminations are inside the motor, which prevents the motor’s energy losses.
  • The stator and rotor are composed of an iron core which induces magnetism.
  • The highly insulated electromagnetic wire prevents damage to other motor parts.
  • The stator with winding is VPI (vacuum pressure impregnation) layered, improving its electrical properties.
  • For ventilation, the structure of the motor is classified into inner and outer air paths.
  • Internal heat is forwarded towards the inner heat dissipation path through the inner fan and rotor air blade.
  • The exterior maintains the internal temperature by dissipating the heat on the base shell.
  • Aluminum or copper can be embedded in place of iron in the stator and rotor to magnetize it.
  • The G1.0 level measures the air space between the stator and the rotor.
  • The axial motion of the fan in the external fan is sustained to dissipate the heat progressively.
  • At 50Hz and 60Hz, it runs with varying speeds depending upon the type of the model.
  • The external fan can also reduce the ventilation noise.
