Abstract: A vibration motor having an insulating housing, a bidirectional coil and a magnetic ring is provided. The insulating housing is of cylindrical shape and at least three position-limiting ribs are protruded from an internal surface thereof. Each position-limiting rib is extended parallel to a central axial line of the insulating housing. The insulating housing has a pair of end plates on two ends thereof. The end plates are made of insulating material. The bidirectional coil is accommodated in the insulating housing and spaced apart from the internal surface of the insulating housing. The magnetic ring is movably accommodated in the insulating housing, and the magnetic ring is arranged coaxially with the insulating housing to surround the bidirectional coil. The position-limiting ribs are disposed adjacent to the magnetic ring and surround an outer edge of the magnetic ring.

Abstract: An energy-saving electromagnetic brake includes a base, a first winding coil, a second winding coil, and a control circuit component. The first winding coil is disposed inside the base, wherein the first winding coil has a first resistance value. The second winding coil is disposed inside the base and is disposed around the first winding coil, wherein the second winding coil has a second resistance value, and the second resistance value is greater than the first resistance value. The control circuit component is disposed inside the base and is electrically connected to the first winding coil and the second winding coil. In a first period, the control circuit component drives the first winding coil. In a second period, the control circuit component simultaneously drives the first winding coil and the second winding coil, and the first winding coil and the second winding coil are connected in series.
