ABSTRACT:
An electricity driven device for rotating a rotary object to increase the rotational inertia of the rotary object. The device includes a fixed and non-rotating main shaft. A fixed element is secured with the main shaft. A rotary element is arranged so as to rotate about the fixed element at a periphery of the fixed element. A coupler is secured with the rotary object. The device also includes an electromagnetic field generating device that includes a first part and a second part. A plurality of coils and a plurality of permanent magnets are provided between the first part and the second part such that an electromagnetic field is generated therebetween when the coils are supplied with electric current, so that the first part and the second part perform relative rotation. The first part of the electromagnetic field generating device is secured on the fixed element. The second part of the electromagnetic field generating device is secured on the rotary element. The coupler is coupled to the rotary object and is pivotally disposed on the main shaft, such that when the rotary element rotates, the coupler and the rotary object coupled thereto rotate therewith to increase the rotational inertia. The device also includes a power supply for transmitting power to the coils.
