The universal motor can be switched from a motor mode to a braking mode. In the motor mode, the armature and the field winding are supplied with an alternating current of a power grid. In the braking mode, the armature is short-circuited and the field winding continues to be supplied with an alternating current from the power grid. In a first phase of the braking mode, the field winding can be supplied with an alternating current having the frequency of the power grid. In a further phase of the braking mode, the field winding is supplied by the power grid with an alternating current having a frequency that is reduced with respect to the frequency of the power grid."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electrodynamic braking device for a universal motor","description":"The invention relates to an electrodynamic braking device and to a method for braking a universal motor having a field winding and an armature.
