What is the 21kv Motor?
21kv device is the high voltage motor that yields the power at maximum rate and shows the voltage range of 21000V. The machine’s body contains different magnetic poles in both the north and south commands that express the casing of stainless steel. This covering acts as a protective shield and protects the device from environmental effects.
The rotor of the device regulates the precise rotation of 21kv. Many other unique features are present in the device, such as no noise during working, low in weight, most resistive body material, and easy to accomplish that you can install anywhere.
Construction of 21kV Motor
The manufacturing of a 21kV motor comprises several types of machinery that pointedly affect the motor’s productivity. Any disruption of its elements can strongly distress the motor’s overall efficiency.
IEC high voltage motors of Longbank present the YXKK, Y, YKS, YKK, YPTKK, and YPTKS series. They have remarkable features with unique functions. The models of 2kV engines have little variations concerning speed, frequency, power, etc. But they all possess a similar component structure inside the motor. A few of these components are elucidated briefly.
Frame:
The frame of the motor makes it highly rigid that can be easily installed. The appearance makes it more attractive and increases the demand for the motor.
Stator:
The 99% pure copper in the 21kV motor improves the productivity and quality of the motor. The windings around the stator are done by hand, which maintains the performance of the motor. The machines possess a protective system to achieve the rated output.
Rotor:
The silicon core and the aluminum casting make the body of the 21kV motor. Some motors replace aluminum with copper to ensure the best results. The shaft of the engine also plays its role in maintaining the motor’s yield.
The Bearing System
All these motors devise a bearing system. These bearings can move fast, or they can be joined together. In contrast, the unconfined bearings fit into motors having a frame size of 80-160. The chief role of these bearings is to maintain a specific space between stator and armature while offering to carry the spinning tools.
Grease Life and Re-Greasing Interval
Any bias in oil will affect the bearing’s lifetime enormously. Longbank’s team is highly skillful in developing the 21kV motor. Several types of oils are used for greasing purposes.
The lifetime of a 21kV motor depends upon several factors, including temperature, operating conditions, motor speed, size of bearings, load size, and weight. You can control your motor’s productivity on your own.
- The bearing’s size can also disturb the smooth functioning of the motor.
- The motor’s variable speed can vary the motor’s output.
- Any disturbance in the ambient temperature can lessen the motor’s performance.
- Any variation in mounting conditions can also reduce the motor’s activity.
Vibration
Extreme vibrational level of 21kV motor affects its smooth functioning of it. However, an excessive vibration will exert a force on the bearings radially and axially. The rotor creates this vibration, which contains some paramagnetic substance embedded inside the motor’s body.
When an alternating current pass through the laminations of the motor, the rotor gets magnetized. The dynamic motion of the armature is under the control of the half-key method.
Anti-Condensation Heater
A raised temperature over a specific range can cause the condensation of the stator’s windings. This process usually occurs in hot summer weather. This phenomenon can be minimized by using anti-condensation heaters in the 21kV motor. The motor and these anti-condensation heaters show their performance interchangeably.
