1. Commercial-Grade Power & High-Torque 1.3 HP DC Motor
At the core of the KitchenAid KSM8990 lies a powerful 1.3 HP Direct Current (DC) motor. Unlike traditional AC motors found in standard tilt-head mixers, DC motors generate maximum torque at low speeds while operating with significantly less noise and thermal buildup.
This quiet, continuous-duty motor drives all-metal gears housed in a solid die-cast zinc body. Whether kneading multiple loaves of stiff bread dough or whipping large volumes of cream, the electronic speed control automatically adjusts power output to maintain consistent planetary mixing action under heavy strain.
2. Heavy-Duty Attachments & 8-Quart Bowl Capacity
The included 8-quart stainless steel bowl features a rugged J-hook handle for easy transport and secure locking. Its extra-wide profile easily accommodates batch sizes of up to 13 dozen cookies or over 8 pounds of bread dough in a single cycle.
To support high-capacity production, the mixer comes standard with NSF-certified stainless steel accessories:
- PowerKnead™ Spiral Dough Hook: Mimics hand-kneading efficiency for dense yeast doughs.
- Flat Beater: Thoroughly incorporates cake batters, frostings, and mashed potatoes.
- Elliptical 11-Wire Whip: Maximizes air incorporation for rapid volume when whipping egg whites or creams.
