Abstract: A system and method for replacing a sixteen-pin ECM with a non-sixteen-pin, field adjustable ECM in an HVAC or other system, and adjusting the performance of the replacement motor at the point of installation. A converter module receives programming information from an existing control board via an existing sixteen-pin harness, and converts the information to six signals. The module includes potentiometers for tuning speed/torque for first and second settings, adjusting a horsepower output of the replacement ECM, and adjusting a ramp time to increase or decrease a rate at which the speed/torque changes. The module includes switches for selecting between clockwise and counterclockwise directions for the replacement ECM, selecting between PWM and non-PWM control, and selecting between torque and speed modes. A non-sixteen-pin motor controller receives the information from the converter module via a four-wire harness, translates the information, and outputs a control signal to the replacement ECM.

Abstract: A system and method for wirelessly communicating with an HVAC motor or other motor in order to manage the motor with regard to, e.g., identifying a suitable replacement for, programming, monitoring and/or diagnosing, and/or tuning or otherwise reprogramming the motor without physically connecting to the motor. A technician uses a software application on a smartphone, tablet, or other portable device to communicate with the motor controller via a wireless communication device incorporated into the motor assembly. The smartphone may receive relevant information, such as identification, programming, or diagnostic information, and process the information or wirelessly transmit the information to a server for processing. Based on the information, the smartphone may transmit programming instructions to the motor controller via the wireless communication device. Further, the wireless communication device may transmit sensor data associated with the motor to allow for monitoring the motor's performance.

Abstract: A system and computer-implemented method for controlling wireless access to the operations of communicative electric motors. An electronic processing element receives an authentication request from a remote access device via a wireless transceiver, approves the authentication request, including determining an associated access level from among a hierarchy of access levels, and grants access to a motor controller to perform actions allowed by the associated access level. Approving the request may be based on receiving a valid password, which may be calculated on the remote access device by a computer program using an electronic key, or by receiving information from an authentication hardware component associated with the device. The various access levels may allow for shutting off, read-only monitoring (of, e.g., temperature, vibration), controlling (e.g., speed), and programming (e.g., tap settings) operation of the motor, and controlling the authentication process (e.g.
