Latest Patents
Doll's latest patents include an innovative over-power safety device for motor-driven systems. This device is designed to detect over-power conditions on the chassis of a motor-driven system. It interrupts the energization of the system when the voltage differential between the system chassis and earth ground exceeds a selected value. This invention is particularly beneficial for systems utilizing multi-phase induction motors, where traditional current sensing safety devices may fail to detect all over-power conditions. The safety device employs a fuse and a motor control relay, ensuring that upon the occurrence of an over-power condition, the fuse becomes non-conductive, thereby opening the motor control relay.
