The Professional model 5KSM7990XEWH has a DC motor with direct drive and no gears between the motor and the attachment, and KitchenAid rates it at 1.3 horsepower at the shaft. The comparison model 5KSM70JPXEWH (Heavy Duty 6.6L) has 0.4 horsepower at the shaft. That's more than three times the actual power reaching the bowl, despite lower energy consumption.
In practice, it shows in the machine not slowing down under heavy load, not behaving worryingly in the middle of a dough batch and not requiring a break after a couple of runs. It is certified for professional use (CEI 60335-2-64), fitted with a wire mesh guard and stop button, two safety requirements in commercial environments. The attachments (6.9L bowl, whisk, PowerKnead dough hook, flex edge beater) are in solid stainless steel without coating, which holds up better in hard daily operation. Capacity: 3.8 kg bread dough, 2.2 kg all-purpose flour, 1.9 litres of whipping cream.
Something surprising: it weighs 13 kg, so 2.2 kg lighter than Heavy Duty, and is 6 cm shallower (31 cm depth versus 37 cm). Electronic speed control with 10 steps between 40 and 200 RPM. Orange cord. Dimensions: 41.9 x 28.7 x 31 cm. Made in the USA.
It is intended for a bakery, restaurant or pastry shop with regular operation. It's not wrong for home use, but there the Heavy Duty model can do a job that won't disappoint you.
