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.
