Are high voltage motors more efficient for the same power

Construction of 11kV Motor

Longbank assembles various high voltage motors along with IEC reduced voltage motors. These motors extant a variety of models which have unusual features. The professional experts of Longbank please their buyers worldwide through its IEC-verified products. Each engine owns multiple parts, which are elucidated herein:

The Bearing System

Some of the series of 11kV motors are YXKK, Y, YKS, YKK, YPTKK, and YPTKS. One of their standard components is the bearing system. This bearing system can be oiled frequently or once in its whole life. Due to this, the 11kV motor is classified into sealed or re-greased motors.

11kV motor presents two forms of bearings, such as moving or restricted. These types of bearings are found in motors with changeable frame sizes. The principal role of this bearing system is to sustain a specific distance between the stator and the rotor and assist in the spinning of objects.


The frame of the 11kV motor seems like a box with an easy installation system. The appearance of the engine makes it more attractive to buyers. Longbank offers multiple motors with varying frame sizes possessing different bearings.


The stator of the motor helps in achieving the rated output. The result of an 11kV motor depends upon the material of the stator, which must be magnetizable. Therefore, 99% pure copper is embedded inside the stator to achieve the highest productivity. Windings around the stator is a hand task.


The rotor contains aluminum casting with a silicon core to maximize the output. Longbank offers several motors that have copper in the rotor. The shafts provide more capacity and efficiency to the motor.

Grease Life and Re-Greasing Interval

The lubricant determines the period of bearings. Any mess in grease’s configuration will cut down the motor’s efficiency. The re-greaseable engines have a prolonged lifetime than eternally greased motors. A hot and cold atmosphere can lessen the motor’s yield.

  • The rise in the motor’s temperature trims down the bearing’s time.
  • Mounting conditions must be monitored to attain the ideal consequences.
  • The speed of the 11kV motor is planned to achieve maximum output.
  • The bearings’ size and the load’s bulkiness also control the motor’s yield.


The toing and froing of the motor generates vibration. The vibration level of the 11kV motor also touches the overall proficiency. An escalation in beat applies more force on the axial and radial edges of the bearings. The rotor comprises small metal sheets that generate poles after passing the alternating current. Half-key soothes the rotors while rotating.

Anti-Condensation Heater

The elevated temperature of the surrounding can condense the windings of the stator. This difficulty is resolved by anti-condensation heaters, which turn on after the motor’s activity. 11kV motor and these heaters accomplish their task interchangeably.

Features of 11kV Motor

An 11kV motor deals with several attractive stipulations that aid the Longbank get more circulation worldwide. A few of its distinctive features converse here briefly:

  • The lifetime of an 11kV engine is 20,000 hours in sealed motors.
  • The re-greaseable motors have a period of 40,000 hours.
