Actuator

An actuator comprising:

• one input control assembly adapted to respond to an external control source, the input control assembly including:
• a first circuit having an input pin adapted to connect to an external control source and a first first-motor pin connected to the first motor, wherein the first circuit input pin is electrically connected to the first first-motor pin;
• a second circuit having an input pin adapted to connect to an external control source and a second first-motor pin connected to the first motor, wherein the second circuit input pin is electrically connected to the second first-motor pin;
• and
• a third circuit having an input pin adapted to connect to an external control source and a first second-motor pin connected to the second motor, wherein the third circuit input pin is electrically connected to the first second-motor pin;
• and
• a fourth circuit having an input pin adapted to connect to an external control source and a second second-motor pin connected to the second motor, wherein the fourth circuit input pin is electrically connected to the second second-motor pin;
• a first geartrain assembly responsive to the input control assembly, the first geartrain assembly including,
• a first motor responsive to the input control assembly,
• a worm wheel connected to the first motor,
• a first rotatable output coupler connected to the worm wheel;
• and
• a second geartrain assembly responsive to the input control assembly, the second geartrain assembly including,
• a second motor responsive to the input control assembly,
• a worm wheel connected to the second motor, and
• a second rotatable output coupler connected to the worm wheel.

An actuator comprising:

• an input control assembly responsive to an external control source;
• a first drive assembly responsive to the input control assembly, the first drive assembly including:
• a first motor responsive to the input control assembly, the motor including a shaft and a first drive gear attached to the shaft;
• and
• a first geartrain assembly having a first driven gear directly engaged by the first drive gear;
• a first rotatable output coupler connected to the first motor via the first geartrain assembly;
• a second drive assembly responsive to the input control assembly, the second drive assembly including:
• a second motor responsive to the input control assembly, the second motor including a second shaft and a second drive gear attached to the second shaft;
• and
• a second geartrain assembly having a second driven gear directly engaged by the second drive gear;
• a second rotatable output coupler connected to the second motor via the second geartrain assembly;
• and
• wherein the first and second driven gears are non-coaxial, and the first and second rotatable output couplers are coaxial.

An actuator comprising:

• an input control assembly responsive to an external control source;
• a first drive assembly responsive to the input control assembly, the first drive assembly including a first motor responsive to the input control assembly;
• a first rotatable output coupler connected to the first motor;
• a second drive assembly responsive to the input control assembly, the second drive assembly including a second motor responsive to the input control assembly;
• a second rotatable output coupler connected to the second motor;
• and
• wherein the input control assembly includes a printed circuit board having four motor pins and four input pins wherein a first two of the four motor pins are connected to the first motor and a second two of the four motor pins are connected to the second motor.
