Abstract
A mixing system comprising a bowl, mixing element and motor. A mixing element is located within the bowl and is driven by a motor to impart mechanical energy to the foodstuff being mixed upon contact. A method for increasing the power to the motor comprises introducing additional current in advance of instantaneous loading.
Claims6
A method of reducing speed variation for a mixing system comprising a mixing element received within a bowl and rotational driven by a motor to mix a foodstuff in the bowl, the method comprising:
- operating the motor at a set speed;
- predicting the occurrence of an increased load on the motor;
- and
- increasing the motor power prior to the occurrence of the increased load to reduce the variation of the motor speed from the set speed.
