Advantages of Slotless Brushless DC Motors

Sinotech’s slotless brushless DC motors have numerous attributes that make them ideal choice for many applications:

  • Zero-cogging torque for smooth operation and minimal vibration
  • High speed capability of up to 100,000 RPM
  • Excellent power-to-weight ratio enabling the design of compact, light-weight hand tools
  • Protected winding for applications requiring autoclavae usage
  • Hall sensors with pull-up resistors and bypass capacitors for electrical noise suppression
  • High energy neodymium magnets maximized output torque
  • Low loss lamination material for increased performance
  • High quality ball bearings for increased life, smooth high speed operation and low noise
  • 200ÂșC insulation for higher reliability

Slotless Brushless DC Motor Technology

The winding of a slotless brushless DC motor is not wound around stator slots as in a traditional brushless motor. Instead, the stator is a cylindrical shaped woven structure placed within the motor’s air gap between the cylindrical lamination stack and the rotor assembly. The slotless design eliminates cogging, yielding a motor with very smooth rotation, and reduced vibration and audible noise.
