Kitchenaid blenders are known for their power and durability, and the Diamond blender is no exception. This blender features a unique motor that sets it apart from other blenders on the market. In this blog post, we’ll take an in-depth look at the type of motor used in the Kitchenaid Diamond blender and why it matters.
An Overview of Blender Motors
The motor is essentially the “engine” of a blender. It provides the power and torque necessary to efficiently blend ingredients. There are two main types of motors used in blenders:
- Induction motors – These feature a basic electromagnetic design and have been used in blenders for decades. They are durable and reliable, but not as powerful or efficient as other motor types.
- Brushless motors – Also known as BLDC (brushless DC) motors, these are more technologically advanced. They provide more torque, require less maintenance, and generate less noise and heat than induction motors. However, they are also more expensive.

The Motor in the Kitchenaid Diamond Blender
The Kitchenaid Diamond blender features a 3 peak horsepower brushless motor. This BLDC motor gives it an advantage over blenders with standard induction motors in several ways:
- More power – With 3 peak HP, the Diamond has 50% more power than the typical peak 2 HP motor found in most blenders. This allows it to blend thicker, denser ingredients with less strain.
- Better torque – Peak horsepower measures maximum output, but torque relates to ongoing grinding power. The brushless motor in the Diamond provides consistent blending torque, even under heavy loads.
- Quieter performance – Brushless motors operate more quietly than induction motors. The Diamond blender produces less noise and vibration during use.
- Increased durability – With fewer internal components subject to wear, brushless motors last longer than induction motors. This adds to the overall durability of the Diamond blender.
- Improved cooling – Brushless motors stay cooler than induction motors while operating. This allows the Diamond blender to run continuously without overheating.

Why the Motor Matters in Blenders
The motor is perhaps the most important factor when comparing blenders. Here’s why it makes a big difference:
- Blending performance – More power and torque mean the motor can handle thicker blends and denser ingredients without bogging down.
- Consistency – A strong motor with sustained torque provides consistent texture and smoothness in blended contents.
- Versatility – Blenders with more advanced motors can grind, puree, chop, crush, and handle most any ingredient thrown at them.
- Durability – Motors with metal driveshafts, ball bearings, and advanced engineering will withstand years of regular use.
- Noise level – More powerful motors tend to generate less noise and run more quietly during operation.
- Safety – Sturdy motors that maintain speeds under load are less likely to overheat or burn out unexpectedly.

Key Takeaways on the Diamond’s Motor
- Kitchenaid opted for a brushless 3 peak HP motor to power the Diamond blender.
- This BLDC motor provides more power, torque, durability, and quieter operation than a typical induction motor.
- The advanced motor allows the Diamond blender to pulverize tough ingredients that would cause other blenders to stall.
- This motor is engineered to run smoothly and maintain speeds even under heavy loads for consistent blending.
- The motor matters when shopping for a quality blender, and the one in the Diamond is built to deliver exceptional performance.
So in summary, the Kitchenaid Diamond blender features an exceptional brushless motor that gives it an edge over blenders with standard motors. This specialized motor allows the Diamond to excel at crushing ice, pureeing thick ingredients, and tackling tough blender recipes without compromise.

FAQs
What is the wattage on the Kitchenaid Diamond blender motor?
The peak wattage is 1400 watts. However, wattage alone doesn’t determine blending power – the 3 peak horsepower rating gives a better idea of the Diamond motor’s capabilities.
What is the maximum speed of the blade?
The Diamond blender blade can reach up to 37,000 rotations per minute (RPM) at high speeds. The brushless motor allows it to maintain these speeds as needed for thorough blending.
Is the motor in the Kitchenaid Diamond blender loud?
No, compared to blenders with less advanced motors, the Diamond operates at lower decibel levels. The noise dampening and cooling features of the brushless motor result in quieter performance.
Conclusion
The motor inside the Kitchenaid Diamond blender is truly what sets it apart. With cutting edge brushless technology providing 3 peak horsepower, this motor can power through any ingredient while maintaining quiet, cool, and consistent operation. When comparing high performance blenders, look for those featuring robust brushless motors that can handle tough jobs without burnout or excess noise. The Diamond’s exceptional motor is built to deliver creamy smoothies, perfectly pureed soups, and other blended treats for years to come.
