Abstract
A washer includes a drum, a motor connected to the drum, a motor drive connected to the motor and configured to supply a driving current to the motor to rotate the drum, and a processor connected to the motor drive. The processor is configured to control the motor drive to supply the driving current to the motor to rotate the motor at a target speed and to determine a magnitude of a load accommodated in the drum while controlling a rotational speed of the motor within a predetermined range.
Claims20
A washer comprising:
- a drum;
- a motor connected to the drum;
- a motor drive connected to the motor and configured to supply a driving current to the motor to rotate the drum;
- and
- a processor connected to the motor drive, and configured to:
- control the motor drive to supply the driving current to the motor to rotate the motor at a target speed;
- and
- determine a magnitude of a load accommodated in the drum while controlling a rotational speed of the motor within a predetermined range.

A control method of a washer comprising:
- controlling, by a processor, a motor drive to supply a driving current to a motor;
- rotating a drum connected to the motor at a target speed;
- controlling a rotational speed of the motor within a predetermined range;
- determining a magnitude of a load accommodated in the drum in response to the controlling of the rotational speed of the motor within the predetermined range;
- and
- controlling the rotational speed of the motor based on the magnitude of the load.
3 more elements
A washer comprising:
- a drum;
- a motor connected to the drum;
- a motor drive connected to the motor and configured to supply a driving current to the motor to rotate the drum;
- and
- a processor connected to the motor drive, and configured to:
- control the motor drive to supply the driving current comprising a sinusoidal current to the motor;
- and
- determine a magnitude of a load accommodated in the drum based on a change in a rotational speed of the motor caused by the driving current comprising the sinusoidal current.
