Abstract

An archery bow is provided including a cam body rotatably joined with a limb and a cam rotation assist device engaging a portion of the cam body so as to urge rotation of the cam body independent of the limb. With the action thereon by the cam rotation assist device, the cam body rotates faster upon initial rotation during a shot cycle when the bow is shot than the cam body otherwise would rotate if the cam rotation assist device was absent. This can reduce the effect of inertia on the cam, and can improve dynamic efficiency of the bow. The rotation assist device can be in the form of a mini limb, a coil spring, programmable magnets and other components that can urge cam rotation of the cam body. The cam body can include a draw stop that engages the mini limb. Related methods are provided.
