Features and operating conditions of medium and high voltage motors
High and medium voltage electric motors are equipped with a laminated core which, before being assembled in the frame, is compressed and protected, then pressed. These particular construction procedures guarantee OME Motors’ high and medium voltage motors excellent insulating performance, greater mechanical resistance, better humidity sealing and a long service life.
The squirrel cage rotor is made of aluminum and equipped with copper bars. Furthermore, the rotor is made with an aluminum casting process and subsequent welding, two necessary steps to ensure maximum reliability and perfect balancing.
Depending on the power and speed of the electric motors, or based on specific customer requests, roller or plain bearings can also be used. The main terminal box is located on the right side of the electric motor but can also be placed on the left, based on specific needs. Both the inside and outside of the terminal box are equipped with separate terminals.
Upon user request, the stator winding and bearings can be equipped with sensors for temperature measurement, ensuring safe and reliable motor operation over time.
Finally, high voltage electric motors can also operate with a frequency converter, thus improving cost savings throughout the device’s life cycle.
The advantages of high and medium voltage electric motors.
Designed and manufactured to measure using the most performing and innovative materials, high voltage motors have technical characteristics capable of ensuring numerous advantages, such as:
- Wide possibility of customization, customizable design based on needs, availability of any constructive form.
- Extremely light, despite its large size.
- Maximum efficiency, constant performance and reliability over time.
- Ease of assembly and maintenance.
- High flexibility of use.
- Low noise and reduced vibration.
- Compliance with international IEC standards.
Fields of application of medium and high voltage electric motors
OME Motors produces medium and high voltage electric motors for safe environments but also for work areas with explosive atmospheres. These devices, in fact, find application in the most diverse sectors, from cement factories to steel mills, from power plants to water purification, treatment and desalination systems, from sugar factories to wind power generation plants
Medium and high voltage motors are also ideal for the application and actuation of pumps, compressors, boilers, conveyor belts, fans and blowers, mills, crushers and shredders, rolling mills and equipment for steel plants, turbines and in general all machinery present in heavy industry. Finally, these motors can be made with squirrel cage or wound rotor.
