Abstract
A method for operating an appliance, such as a stand mixer, is provided. In one example implementation, the method can include operating a motor of the appliance in a first direction. The method can further include detecting, by a feedback system of the appliance, a first trigger condition. The method can further include, responsive to detecting the first trigger condition, operating the motor of the appliance in a second direction that is different than the first direction.
Claims20
A method for operating an appliance, the method comprising:
- operating a motor of the appliance in a first direction;
- detecting, via a sensorless feedback system, a first trigger condition;
- and
- responsive to detecting the first trigger condition, operating the motor of the appliance in a second direction, the second direction being different than the first direction.
A stand mixer appliance, comprising:
- a base;
- a housing pivotally mounted to the base;
- a motor assembly comprising a motor disposed within the housing;
- a mixer shaft rotatably mounted on the housing;
- and
- a controller operably coupled to the motor, the controller configured to:
- operate the motor in a first direction;
- detect a first trigger condition;
- and
- operate the motor in a second direction in response to detecting the first trigger condition, wherein the first direction is different than the second direction.
A motor assembly for a stand mixer, the motor assembly comprising:
- a motor, the motor comprising at least a rotor;
- a motor drive;
- a sensorless feedback system configured to obtain feedback measurements of one or more electrical characteristics from the motor;
- and
- a controller operably coupled to the motor, the controller configured to:
- operate the motor in a first direction;
- detect a first trigger condition;
- and
- operate the motor in a second direction in response to detecting the first trigger condition, wherein the first direction is different than the second direction.
