Maintenance and motor rewinding of asynchronous motors
Unlike synchronous motors, in asynchronous motors the alternating current induced in the rotor rotates at a slightly lower speed than the stator’s magnetic field, creating a small speed difference called slip, which enables the generation of mechanical torque that drives the motor shaft.
Electromotor provides preventive maintenance, predictive maintenance and corrective maintenance for asynchronous motors, including the removal of burnt windings or damaged windings from the stator caused by overheating, short circuit, moisture ingress, wear or other factors.
We also have full expertise in motor overhaul, rotor balancing, restoration of electrical insulation and assembly of components for asynchronous motors with both single-phase and three-phase motors, ensuring high performance and reliability.
Choose Electromotor for the purchase or maintenance of asynchronous motors with both single-phase and three-phase power supply.
We supply motors with squirrel cage rotor or wound rotor motors (slip ring motors) and operate throughout Italy and across Europe. Contact us!
Types of services we perform on asynchronous motors
Electromotor primarily provides routine maintenance on asynchronous motors, including interventions such as bearing lubrication, motor cleaning, insulation resistance testing and periodic electrical checks.
We also perform predictive maintenance, based on monitoring motor condition using diagnostic tools. This includes vibration analysis to detect imbalance and misalignment, infrared thermography to identify abnormal overheating, and electrical testing on windings.
Finally, corrective maintenance includes motor rewinding of burnt windings, which restores the electrical core of the asynchronous motor, as well as bearing replacement and other types of mechanical repairs.
Why asynchronous motors are widely used in industry
Patented with a three-phase system by the renowned engineer Nikola Tesla in 1888, asynchronous motors today account for approximately 90% of industrial motors.
Why are they so widely used? Asynchronous motors offer several advantages: high resistance to mechanical stress, dust and harsh environments, versatility with a wide range of power ratings, and high energy efficiency.
In addition, these motors are cost-effective both in terms of purchase and operation, as they do not include commutators or brushes (unlike direct current motors), feature a robust enclosed rotor, and, thanks to proper bearing lubrication and periodic cleaning, can operate reliably for years.
Are you in the metallurgical industry, steel industry, chemical processing or any other sector using asynchronous motors? Contact Electromotor for fast and professional maintenance services.
We operate throughout Italy and across Europe.
