Silent. Reliable. Long-Lasting.


Sensorless brushless DC motors have achieved wide appeal in the medical community within the last five years. Long life expectancy for motors is crucial for medical applications: while brushed motors last anywhere from 2,000 to 5,000 hours. KDE Direct's brushless motors have a lifespan of 10,000 hours. Our motors are more efficient, compact, and reliable than brushed motors, resulting in durable and dependable medical equipment so you can focus on your procedures rather than battery life or the constant whirring noises associated with brushes.

It's crucial that motors used for hospital or patient-care facilities are quiet enough to comply with low noise level standards. Motors used for respiratory needs in sleep apnea equipment operate at high speeds yet need to comply with even lower noise level standards since the medical equipment will be in the patient's bedroom at home while they sleep. The absence of the commutator and brushes in BLDC motors helps to significantly reduce motor noise.

Brushless Motor Advantages:


Brushless motors have higher efficiency and performance and a lower susceptibility to mechanical wear than brushed motors.

  • High torque per watt of power input (increased efficiency)
  • High torque to weight ratio
  • Reliability with low maintenance requirements
  • Decreased operational and mechanical noise
  • Extended lifespan (no brush and commutator erosion)
  • Removal of ionizing sparks from the commutator (ESD)
  • Near-elimination of electromagnet interference (EMI)
