Why is a Brushed DC Motor Preferred for Grinder Applications?

The preference for brushed DC motors in grinders (especially coffee grinders) is primarily driven by key factors such as cost control, torque characteristics, control simplicity, and application suitability. Below is a detailed analysis: For example, a home coffee grinder (such as those used by Philips) utilizes Donghong Electromechanical's D53 brushed DC motor with a power rating of 300W, at a cost of less than $9, whereas a brushless solution with the same power output would cost over $18.
