In a previous post, Nate Hirst discussed the advantages of a high-powered blender. When it comes to making milk shakes, ice cream, fruit smoothies, peanut butter and other thick blends, you'll appreciate the extra Blendtec Blender Motor power Blendtec offers. So what makes a Blendtec blender so powerful? It’s all in the motor. Place our armature (the spinning part of the motor) next to one from a low-powered blender, and it's easy to see which one would win a fight. Our commercial-grade motor is rated at 1560 watts—more than 4 times the rating of lower-powered blenders! To look at it from another perspective, a standard washing machine motor is rated at about 920 watts, while a shop vacuum and microwave are rated at approximately 1000 watts. All of that power creates a lot of heat. We cool the motor using a specially designed seven-bladed fan. The fan blades are unevenly sized and spaced, eliminating the resonance effects (which create a loud noise) common in standard fans. This allows us to keep the motor cool with a minimum of fan noise. Carbon Bearings On A Blendtec Blender[/caption] We mount the armature using two carbon steel bearings, in contrast to the bronze bushings used in most low-power blenders. Bearings are quieter than bushings, allow for higher speeds (up to 28,000 rpm in our blenders), and provide longer life. So, is it really necessary to have such a big motor? If all you plan on doing with your blender is mix relatively soft ingredients, then maybe not. But if you want to crush ice and frozen fruit, blend grain into flour, turn granulated sugar into powdered sugar or make soup in seconds, then you need a high-powered blender.
