Simulated Mass Rotation Systems and Methods

A digital handwheel system comprising:

• a mounting bracket;
• a motor having an output, the motor coupled with the mounting bracket;
• a handwheel coupled with the output, the handwheel coupled with the mounting bracket;
• wherein the motor is positioned at least partially within the handwheel such that the output and the hand wheel rotate about coaxially oriented axes of rotation;
• a rotation detector configured to detect rotation of the handwheel;
• and
• a controller electrically coupled with both the rotation detector and the motor, thereby forming a closed-loop control system for the motor that uses a detected rotation of the handwheel to simulate a rotational inertia of the handwheel that is different from the handwheel's actual rotational inertia.

A digital handwheel system to control camera movements comprising:

• a motor having a rotor;
• a handwheel coupled with the rotor such that a rotation of the handwheel causes the rotor to turn;
• a rotation detector configured to detect a rotation of the handwheel;
• and
• a controller electrically coupled with both the rotation detector and with the motor, configured to operate a control system for the motor that uses the detected rotation of the handwheel to generate a simulated rotational inertia of the handwheel that is greater than the handwheel's actual rotational inertia such that the controller causes the handwheel to continue to turn according to the simulated rotational inertia upon applying the rotation to the handwheel;
• and
• a remotely-located motor configured to receive a signal from the controller to cause the remotely-located motor to rotate according to the rotation of the handwheel.

A digital handwheel system to control camera movements comprising:

• a first motor having a first rotor;
• a first handwheel coupled with the first rotor such that a first rotation of the first handwheel causes the first rotor to turn;
• a first rotation detector configured to detect the first rotation of the first handwheel;
• a controller electrically coupled with both the first rotation detector and with first the motor, configured to operate a first control system for the first motor that uses the first detected rotation of the first handwheel to generate a first simulated rotational inertia of the first handwheel that is greater than the first handwheel's actual rotational inertia such that the controller causes the first handwheel to continue to turn according to the first simulated rotational inertia upon applying the first rotation to the first handwheel;
• a second motor having a second rotor;
• a second handwheel coupled with the second rotor such that a second rotation of the second handwheel causes the second rotor to turn;
• a second rotation detector configured to detect the second rotation of the second handwheel;
• and
• a controller electrically coupled with both the second rotation detector and with second the motor, configured to operate a second control system for the second motor that uses the second detected rotation of the second handwheel to generate a second simulated rotational inertia of the second handwheel that is greater than the second handwheel's actual rotational inertia such that the controller causes the second handwheel to continue to turn according to the second simulated rotational inertia upon applying the second rotation to the second handwheel;
• wherein the first handwheel is configured to control rotation about a first axis and the second handwheel is configured to control rotation about a second axis.
