Braking Device for a Universal Motor |
摘要 |
An electrodynamic braking device for a universal motor includes a field winding configured to be fed from a grid during a braking operation, and an armature that is configured to be directly short-circuited. A braking process is performed by means of control electronics. Good braking is achieved with relatively low brush wear. Such an electrodynamic braking device can be used effectively for a power tool. |
