Abstract:
To increase motor response speed more than ever in a motor device with a reducer that is configured to transmit motor power at both ends of an output shaft of the reducer.
In a motor device, a mechanical paradox planetary gear reducer 3 is connected to an end of a motor 2 that has a hollow motor shaft 22 fixed to the center of a rotor 25 positioned on an inner side of a stator 26. An output shaft 4 is passed through the motor shaft 22 and fixed to the center of an output shaft base 335 of the reducer 3, with both ends of the output shaft 4 exposed to the outside.
