What are the 4kv Motors?

4kv motor is a three-phase induction motor that yields the energy of 4000w. Asynchronous motor represents the weight of 10kgs with multiple ways of protection. ISO-certified products apply to fans, mills, pumps, mixers, compressors, conveyors, and cranes.

The device’s rotor maintains the machine’s torque or rotation at an accurate rate. The resistive casing of the machine protects it from environmental possessions. Anti-condensational heaters also safeguard it from stickiness.

Construction of 4kV Motor

Longbank presents multiple series of its products, including the YE2, YVFE2, YBX3, and YE3 series. Each sequence differs by a few specifications. You can contact our brand to buy a 4kV motor for a reasonable amount. The increasing demand for a 4kV engine is due to its increased efficiency. Productivity is usually measured by its multiple components, which are described here briefly:

The Bearing System

The 4kV motor of this brand is certified whose bearings can be free floating or confined. The significant purpose of these bearings is to sustain a specific distance between the rotor and the stator. FS80-FS160 motors offer free approaches. It also provides support for the loaded objects.

Grease Life and Re-Greasing Interval

Grease helps in maintaining the bearing’s lifetime. Any variation in grease composition will significantly reduce the motor’s efficiency. You must opt for an appropriate method for lubricating a bearing. Those oiled motors frequently have an enhanced lifetime than the other motors.

The expert engineers and employees of Longbank are highly efficient in manufacturing great motors. The temperature of the surrounding can significantly decrease the lifetime of the engine. The correctly observed mounting conditions improve the lifespan of the motor.

The speed of the motor must be accustomed to get high productivity. Over a precise speed limit, the motor’s bearings feel more radial and axial compression, which can rupture the engine. Similarly, the bearing’s size and weight affect the motor’s proficiency.


The motor produces shaking during its working. This gesture is made by the armature, which comprises metal sheets for engendering the north and south poles in the metal sheet. The half-critical method is commonly observed for maintaining the rotor.

Anti-Condensation Heater

The hot summer weather can cause the condensation of the stator’s windings. The only thing we can control is the conservation of motor efficacy by maintaining the performance of different tools. So, Longabank has installed anti-condensation heaters inside the motor to rally the motor’s efficiency. Motor and these heaters accomplish their tasks alternately.

Rated Output

You can attain the optimum results of a 4kV motor by managing its operating conditions. It consists of temperature and altitude. The temperature must be in an array of -15oC to 40oC, while its height must be 1000m.

Voltage and Frequency

4kV motors present two major classes, which are IEC60034-1 certified. The class A motors can perform well at even high temperatures. Class A’s voltage and frequency fluctuation can be ±5 % and ±2%, respectively, while these vary by ±10% and +3% / -5% in class B motors.

Features of 4kV Motor

Each motor possesses peculiar features which assist in boosting the overall productivity of the motor. Some of its structural properties are enrolled here:

  • The one-time lubricated motors have a lifetime of 20,000 hours.
  • The regular oiling enhanced the lifespan up to 40,000 hours.
  • Increased CT (coolant temperature) will decrease the bearing’s lifetime by one-half.
  • The power of the 4kV motor is different in different models.
  • The input voltage of this motor is 4000V.
  • The sturdy nature of the motor is due to its particular body material.
  • The rotor and stator’s body material can be magnetized.
  • The radiator’s structure is a vertical-horizontal shape that maintains the motor’s temperature.
  • The design of the motor attracts buyers all over the world.
  • Laminations inside the motor reduce the energy losses.
  • The wire’s insulation prevents the motor’s components from being damaged.
  • The VPI technique can provide better electrical properties.
  • Internal and external fans dissipate the heat and sustain the smooth functioning of the motor.
  • 0 technique helps calculate the air gap between the stator and the rotor.
  • At different frequencies, the speed of the 4kV motor is different.
