The brushless engine cooling fan drives ECM and FED can be used both in combustion engine thermal circuits and in electric vehicles. The electronic motor commutation allows for continuous speed control. As compared to conventional brush motors, the new drives provide advantages in terms of efficiency, packaging, electromagnetic compatibility, temperature resistance and robustness with regard to environmental influences.
