• Minimize energy losses
• Prevent environment pollution
• Decrease acoustic noise and power harmonics
• Increase system performanceversus- cost ratio
• Increase productivity, flexibility and robustness
• Increase safety and reliability
• Reduce system size and weight
• Growth of digital control and reducing usage of analog components and total system cost.
Motor types that most effectively meet these requirements include AC induction motors (ACIM), permanent magnet synchronous motors (PMSM), brushless DC motors (BLDC) and switched reluctance motors (SR).
