Induction motors are investment pieces; they are heavy duty, long lasting machines and their motors often come with a 20 year guarantee. They use magnets to generate large amounts of power. When they reach optimum power, they are able to hold it for sustained periods of time. They often come with a thermal cut out feature to prevent damage caused by overheating. Generally induction powered machines will have 1 or 2 power settings, the second usually loosening the torque.
Induction powered machines are perfect for large amounts of food preparation on a regular basis and deal comfortably with demanding tasks like mixing bread dough and making nut butters.
