Latest Patents

Among his latest patents are a motor protection device and a method for protecting a motor, as well as a load protection system. The load protection system features a PLC transmitter module and a PLC receiver module, which communicate a plurality of bits of data. Each bit is transmitted near a zero-crossing of the voltage on the power lines supplying power to the load, in the form of a high-frequency burst of pulses. The pulses are structured in two patterns, where the first pattern identifies the start of the second pattern, and the second pattern includes the data. The first pattern is unique and not represented within the second pattern. The load may be a motor, and the data may include a parameter value representing a parameter of the motor. Another significant patent is a motor drive system that includes a removable bypass circuit and/or cooling features. This motor control system drives an alternating-current (AC) motor and includes a motor drive with a power circuit and a motor drive controller. The controller is configured to generate a motor voltage and command the bypass controller to connect the AC motor to the line voltage source when the speed reference is substantially equal to the line
