- Motors are an integral part of the modern world. Each one of us is influenced by motors every day. There is no escaping them. Motors convert electrical energy very efficiently into rotational shaft power for use in mechanical systems. More than 60 percent of power used in industrial plants is delivered to the load via an electric motor. The most common motor in the industrial world is the squirrel cage induction machine. There are, in addition, other types of motors each supplying a particular need and appropriate for different applications: DC motors, DC brushless motors, synchronous and synchronous reluctance motors, wound rotor induction motors, doubly fed induction motors, and stepper motors.
- RGLSolutions has a thorough understanding of and appreciation for motors and their applications. Motors fulfill a specific role in industrial systems. They must perform efficiently and they must be compatible with the system as a whole.
- Issues that arise associated with Motor applications may include:
- Choosing the right motor
- Motor rating (sizing)
- Maintenance schedules
- Motor bearing failure
- Motor bearing noise
- Motor winding failure
- Viability of rewinding failed motors
- Overheated motors
- Rising energy consumption and costs (How much energy is consumed by a motor?)
- Appropriate/inappropriate use of energy efficient motors
- Motor frame vibration
- Motor shaft vibration
- The proper use of inverter duty motors
- NEMA MG1 standard
- Motors are integral to the advanced control and power technologies available for twenty-first century energy efficient systems. It is critical that they are understood and applied correctly for optimum results.
- RGLSolutions has the knowledge and experience to diagnose and solve problems associated with motors in industrial applications.
- In a sample case history newly installed energy efficient motors that replaced standard motors were reported to be vibrating at 120Hz. This was the cause of much concern since it appeared that technological advance was presenting itself as a technological problem. An expert and experienced diagnosis solved the problem by correcting supply voltage unbalance.
