Latest Patents
One of Schwesig's latest patents is focused on drive control for a three-phase AC motor via an inverter using safe technology. This invention combines two technically contrasting functions: "safe stopping" and "braking by armature short-circuiting." It employs two means for pulse inhibition to block the respective current valves in the event of a fault, ensuring safety by interrupting the supply voltages for driving the control valves. Additionally, for braking by armature short-circuiting, the stator winding of the motor is short-circuited in case of a fault, allowing for operational safety.
Another significant patent by Schwesig is related to safe speed monitoring for sensor-free three-phase drives. This invention enables a safety function for speed monitoring in induction machines operated on an inverter without a sensor system. It limits and monitors a determined setpoint stator frequency value in a two-channel mode, deriving control signals for the electrical valves of the inverter. In the event of fault detection, a two-channel switching off
