What are the 1kv Motors?

1kv Motors are a three-phase system with a rotational speed of 3000rpm at 50Hz. Asynchronous motor shows the IE1 efficiency with the stator current of 95 to 200A. The machine rotates at 3000rpm at 50Hz and is asynchronous. Stator current ranges from 95 to 200A. ISO certified brand and applicable in crushes, mills, cranes, mixers, compressors, conveyors, and fans.

The rotor of the device keeps the rotation precise and accurate. Optimum features of the device enhance its products such as no noise pollution, environment friendly, and low in weight. The device’s body contains resistive material that protects the device from environmental effects. Anti-condensational heaters also protect it from humidity.


Construction of 1kV Motor

While manufacturing a 1kV IEC low voltage motor, several parts are installed inside the motor’s body. These components are highly efficient in determining the overall productivity of the engine. A few of its elements are described here briefly:

The Bearing System

Longbank offers numerous series of IEC low voltage motors. Some of these series are IE2, YVFE2, YBX3, IE3, and IE4. The bearing system of these motors is usually greased in intervals to improve the motor’s yield.

The bearing system of the 1kV motor either floated or joined. Unconfined bearings belong to engines with a frame size of 80-160. The maintenance of a certain distance between the stator and the rotor is under the control of bearings. They also provide support to the rotating load.

Grease Life and Re-Greasing Interval

The bearing’s period depends upon the type of grease. Any variation in the lubrication method will primarily affect the motor’s productivity. Oiling the engine in regular intervals improves the lifetime of the 1kV motor. Some other factors include the exterior temperature, operating conditions, motor speed, type of bearing system, and load.


When the 1kV motor is turned ON, it produces vibration. The rotor contains small metal sheets which have poles like a magnet. Half-key assists in the stabilization of the rotors. Any hindrance in the average speed of the motor leads to a reduction in the motor’s efficiency.

Anti-Condensation Heater

During summer weather, the high temperature affects the motor’s windings. This problem is resolved by installing anti-condensation heaters. These heaters and the motor itself work in alternate manners.

Rated Output

While manufacturing a 1kV motor, all its standard operating conditions are kept in view so that you can achieve a rated output. Two main conditions are temperature (-15oC to 40oC) and its height (1000m) above sea level.

Voltage and Frequency

Class A motors’ voltage and frequency fluctuations are ±5 % and ±2%, respectively. While for class B motors, the same factors vary by ±10% and +3% / -5% respectively. Both of these classes are IEC certified. Class A motors can bear a temperature of 10K more than class B motors.

Features of 1kV Motor

A few peculiar features of a 1kV motor are elaborated here:

  • One-time lubricated motors have a period of only 20,000 hours.
  • Frequent oiling upgrades the lifetime up to 40,000 hours.
  • The bearing’s lifetime is inversely related to the temperature.
  • The power of this motor is 0.75kW to 2500kW.
  • The potential difference is 1000V.
  • Cast iron makes the sturdy frame of the motor.
  • The outlook of the motor is outstanding.
  • Metal sheets help in the maintenance of energy losses.
  • The insulation of electromagnetic wire prevents the damage loss of other components.
  • VPI layering protects the motor’s windings.
  • Ventilation is maintained through two different pathways such as external and internal mechanisms.
  • Both these components follow different ways to expel the heat.
  • The inner fan dissipates the internal heat towards the ventilation path. At the same time, the outer fan expels it to the outside. It helps in maintaining the motor’s temperature.
  • G1.0 scale helps calculate the air gap between the rotor and the stator.
  • 1kV motor is available at variable speed.

The outer fan can reduce the motor’s working noise.
