Abstract
Examples of the present disclosure relate to various aspects of architectural structure coverings. A particular aspect relates to using controlling a motorized architectural covering that includes a motor and a magnetic brake. In an example, a shaft of the motor is controlled to enter a rest position, in which south and north poles of the magnetic brake are aligned.
Claims20
An architectural structure covering that comprises:
- a covering load;
- a motor comprising a motor shaft that is coupled with the covering load;
- a magnetic brake;
- and
- a motor controller configured to:
- stop a rotation of the motor shaft;
- determine that the rotation has stopped;
- cause, upon determining that the rotation has stopped, an alignment of a magnetic pair of the magnetic brake, the alignment causing a further rotation of the motor shaft to a hold position;
- and
- maintain the motor shaft at the hold position.
A method implemented by a motor controller of an architectural structure covering, the method comprising:
- stopping a rotation of a motor shaft of a motor coupled to a covering load of the architectural structure covering;
- determining that the rotation has stopped;
- causing, upon determining that the rotation has stopped, an alignment of a magnetic pair of a magnetic brake of the motor, the alignment causing a further rotation of the motor shaft to a hold position;
- and
- maintaining the motor shaft at the hold position.
A non-transitory computer-readable storage medium storing instructions that, upon execution by a motor controller of an architectural structure covering, cause the architectural structure covering to perform operations comprising:
- stopping a rotation of a motor shaft of a motor coupled to a covering load of the architectural structure covering;
- determining that the rotation has stopped;
- causing, upon determining that the rotation has stopped, an alignment of a magnetic pair of a magnetic brake of the motor, the alignment causing a further rotation of the motor shaft to a hold position;
- and
- maintaining the motor shaft at the hold position.
