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.
