A study on the design and manufacture of HVAC Double Cylinder Motor for a car blower

In the recent years, electrical motors have been developed for a car blower. Their requirements are the high efficiency, low cogging torque, long life and low cost. In this paper, a double cylinder motor for a car blower was designed, manufactured and tested with low noise, vibration and low Hysteresis loss because of the slotless and double cylinder structure.
