Abstract
A washing machine appliance, including methods for operation, is provided herein. The washing machine appliance may have a tub and a basket rotatably mounted to a motor and within the tub. The basket may define a chamber for receipt of articles for washing. The method may include spinning the basket; calculating a torque value; accelerating the basket to an elevated rotational speed; determining an acceleration rate; determining a mass moment of inertia; and adjusting acceleration of the basket.
Claims18
A method for operating a washing machine appliance, the washing machine appliance having a tub and a basket rotatably mounted to a motor and within the tub, the basket defining a chamber for receipt of articles for washing, the method comprising:
- spinning the basket at a set dwell speed;
- calculating a torque value based on the set dwell speed;
- accelerating the basket to an elevated rotational speed;
- determining an acceleration rate during accelerating the basket;
- determining a mass moment of inertia based on the calculated torque value and the determined acceleration rate;
- and
- adjusting acceleration of the basket according to the determined mass moment of inertia.
A washing machine appliance, comprising:
- a tub;
- a basket rotatably mounted within the tub, the basket defining a wash chamber for receipt of articles for washing;
- a valve;
- a nozzle configured for flowing liquid from the valve into the tub;
- a motor in mechanical communication with the basket to selectively rotate the basket within the tub;
- and
- a controller in operative communication with the valve and motor, the controller configured to initiate an operative cycle comprising
- spinning the basket at a set dwell speed,
- calculating a torque value based on the set dwell speed,
- accelerating the basket to an elevated rotational speed,
- determining an acceleration rate during accelerating the basket,
- determining a mass moment of inertia based on the calculated torque value and the determined acceleration rate, and
- adjusting acceleration of the basket according to the determined mass moment of inertia.
