Technical Advantages of a Permanent Magenet Brushless System

• Longer Operating Life
  Eliminating brushes substantially increases the over all mean time between failures (MTBF) of the system.
  
  
• Improved Efficiency
  With efficiency ratings as high as the mid-90s, the brushless system has a higher efficiency than equivalently rated brush, induction, stepper or switched reluctance system. In addition, a brushless system operates at a higher efficiencies over a wider operating range than competing technologies.
  
  
• Higher Speed
  Rotational speed of the motor is not limited by the surface contact between the motor brushes and the commutator. Higher speeds up to as much as 100,000 RPM are feasible with brushless motors.
  
  
• Lower Thermal
  Resistance The windings in a brushless motor are located on the stationary member, allowing heat to be removed efficiently via conduction. Operating at lower temperatures improves the life of the motor as well as its MTBF.
  
  
• Clean Operation
  The elimination of brushes prevents the build-up of dust that occurs in brush systems.
  
  
• Reduced Size and Weight
  A brushless system is quieter than an equivalent rated brush, induction, stepper or switched reluctance system.
  
  
• Quieter Operation
  A brushless system is quieter than an equivalently rated brush, induction, stepper pr switched reluctance system.
