Motor torque and speed

Key Concepts

• Motor Torque:

• Determines the grinder’s ability to maintain consistent burr rotation under load.

• Higher torque helps grind dense or oily beans without stalling.

• Important for espresso grinders where fine settings increase resistance.

• Motor Speed (RPM):

• Fast motors can grind quickly but may generate more heat and fines.

• Slower motors reduce heat buildup, preserving coffee aroma and flavor.

• Some grinders allow variable speed for fine control over particle distribution.

• Heat and Retention:

• High torque with moderate speed minimizes friction and overheating.

• Critical to avoid bean scorching or flavor degradation.

• Practical Implications:

• Commercial grinders often use high-torque motors to handle continuous operation.

• Home grinders can benefit from slower, torque-optimized motors for specialty coffee.

Summary

Balancing motor torque and speed ensures consistent particle size, protects coffee quality, and improves extraction repeatability.
