Motorized camera head with pcb motors

A modular camera head system, comprising:

• a first motor comprising a first stator and a first rotor, wherein the first rotor comprises two portions that together form a slot, and wherein the first stator extends into the slot of the first rotor;
• a second motor comprising a second stator and a second rotor, wherein the second rotor comprises two portions that together form a slot, wherein the second stator extends into the slot of the second rotor, and wherein the second motor is mechanically coupled with the first motor;
• a bus power system configured to bundle power and a multi-point control bus, the bus power system being electrically coupled with each of the first motor and the second motor;
• wherein each of the first motor and the second motor is configured to be operated via the multi-point control bus, such that the first motor and the second motor are each operable independently of the presence of any other motor in the camera head system;
• and
• wherein the bus power system is configured to permit reconfiguration of the camera head system by selectively removing or adding motors that operate via the multi-point control bus.

A camera head system, comprising:

• a roll motor comprising an annular roll motor stator and a roll motor rotor, wherein the roll motor rotor is formed as an annulus having an open center portion sized and dimensioned to receive at least a portion of a camera therein;
• a tilt motor comprising a tilt motor stator and a tilt motor rotor;
• a tilt motor mounting frame coupling the tilt motor with the roll motor, wherein the tilt motor mounting frame is configured such that the tilt motor is slidable along the tilt motor mounting frame and tightenable at a selected position along the tilt motor mounting frame to align an axis of rotation of the tilt motor with a center of mass of a camera payload coupled with the roll motor;
• and
• a pan motor comprising a pan motor stator and a pan motor rotor, wherein the pan motor is coupled with the tilt motor by a pan motor frame.
