Construction of 3.3kV Motor

Longbank offers several categories of motors, including YXKK, Y, YKS, YKK, YPTKK, and YPTKS. All these series present multiple models that have varying specifications. But the primary components are approximately similar in all types of motors.

Each component is particular in its function that maintains the smooth functioning of the motor. Any commotion in the parts of the engine leads to a reduction in the overall productivity of the motor. A few of these components are described here briefly, and you can have a piece of knowledge about them at a glance.

The Frame

The frames of the machine are box-shaped, which aids in the easiness of installation and maintenance. Flexibility in structure for building and outlook can be customized according to the need of the client.

Stator

The stator of the device contains 99% pure copper, ensuring the device’s quality and efficiency. Better insulation system with five flows of processing. All the windings are fitted by handwork to confirm the not winding flow.

Rotor

The rotor of the device contains the casting of aluminum with the core of silicon steel which ensures the quality of the device. Various devices also include the rotor of a copper bar. Well-defined shafts in the machine represent the excellent capacity and strength of the device.

The Bearing System

The primary component of the 3.3kV motor is its bearing system. This bearing can be confined or open-ended. Both of these bearings control the motor’s function. The significant role of these bearings is to adjust a particular distance between the rotor and the stator, along with supporting the loaded items.

Grease Life and Re-Greasing Interval

Grease controls the bearing’s lifetime. Variations in the composition and the type of the oil can dramatically reduce the motor’s functionality. Countless lubricants are used for greasing the engine. Regular lubrication expanded the lifetime twice that of a one-time lubricated 3.3kV motor.

Vibration

When the armature rotates, the vibration is produced. The body of the armature contains metal sheets known as laminations that act as magnets after the passing of alternating current. Half-key stabilizes the armatures dynamically.

Anti-Condensation Heater

Increasing temperature over a specific limit can cause condensation of the motor’s windings, reducing the motor’s efficiency. This incident typically occurs in scorching summer weather. Longbank has installed anti-condensation heaters in its motors to eliminate this problem. These heaters are turned ON after the working of the motor.
