Ease of use: BDC Motors

You can achieve energy and cost efficiency by selecting one of our designated solutions for the various types of BDC motors, all in proven Infineon quality you can depend on.

The key characteristics of BDC are:

  • Easy to control: torque is proportional to current – speed is proportional to voltage – Bi-Directional drive only by changing polarity of voltage-supply
  • Moderate efficiency: Therefore used more in applications running not permanently
  • Variable speed: fewer external components required than induction or brushless DC motors
  • Maintenance necessary as brushes wear out
  • Louder than induction motors (EMI and audible)

In Automotive we find BDC-Motors in a broad variety of applications such as:

  • Window-Lift and Sun-Roof
  • Fans ( e. g. HVAC-Fan)
  • Pumps (e. g. Fuel-Pumps or Water-Pumps)
  • Tail-Gate or Door-Opener
  • Flaps for e. g. HVAC or in the exhaust-channel

Depending on specific circumstances and boundary conditions, customers choose their optimal system-design. Most relevant are:

  • Power-Requirements
  • Uni- or Bi-Directional Drive
  • Voltage-Supply
  • Space-Constrains
  • Dynamic/Control requirements
