Abstract: An electronic control module is provided. The electronic control module is operably connected to a power supply for providing power to a motor. The electronic control module includes an input device, a processor coupled to the input device, and first and second current supply lines. The processor is configured to generate a command signal in response to an input supplied by the input device and transmit the command signal to the motor. The command signal controls an operating point of the motor. The first and second current supply lines are operably connectable to the motor and the processor. At least one of the current supply lines, the input device and the processor are adapted to utilize the current supply lines both to transmit power to the motor and to transmit the command signal to the motor over the current supply lines.

Abstract: A fuse holder for holding a fuse is provided that includes a body, a line side connector supported by the body, and a load side connector supported by the body. The fuse holder also includes a toggle switch supported by the body and capable of toggled engagement in a first position that provides electrical connection. The switch is also capable of toggled engagement in a second position that provides electrical isolation between the line side connector and the load side connector. The fuse holder also includes a fuse carrier. The fuse carrier is supported by the body and adapted for holding the fuse and the fuse carrier is adapted to be removed from the fuse holder. The fuse holder includes a blocking device blocking the toggled engagement of the switch from the second position to the first position when the fuse carrier is not within the fuse holder.

Abstract: A motor controller for an electric motor for driving a blower to generate an airflow. The motor controller includes a processor and a drive circuit configured to regulate power supplied to the motor to turn the blower. The processor computes a system resistance for the blower based on a fixed set point for a first control parameter and a feedback parameter. The processor receives an airflow rate demand value and computes an operating set point for a second control parameter based on the system resistance and the airflow rate demand value. The processor controls the drive circuit based on the operating set point to supply electrical power to the electric motor and to operate the blower to generate the airflow.

Abstract: A fan drive circuit for a variable speed fan motor in a cooling system, includes an inverter configured to supply a current signal to stator windings of the variable speed fan motor, a frequency detection circuit coupled to an output stage of an inverter of a compressor motor of the cooling system and configured to detect a first frequency of a compressor current signal at the output stage of a variable speed compressor drive circuit and generate a frequency signal, and a digital signal processor (DSP) coupled to the inverter and the frequency detection circuit. The DSP is configured to receive the frequency signal corresponding to the first frequency from the frequency detection circuit, select a second frequency corresponding to the first frequency at which to operate the variable speed fan motor, and transmit control signals to the inverter to supply current to the stator windings at the second frequency.
