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.

System and method for wirelessly managing electric motors

A system-specific interface module for a motor control subassembly for controlling operation of an electric motor within a larger system which uses a particular system communication method. The motor control subassembly includes a standard power module and the interface module. The power module includes a controller processor configured to receive input for controlling and to generate output regarding operation of the motor. The interface module includes a communication interface hardware block configured to exchange input and output signals with the larger system, and an interface processor configured to translate the input and output signals between the particular system communication method used by the larger system and a standard internal communication method used by the power module. Thus, the motor control subassembly can be configured to accommodate any of a variety of different system communication methods and other input/output options by selecting and inserting the appropriate interface module.

System-specific interface module for motor control subassembly for electric motor

A motor assembly broadly includes a motor, a motor controller, and an interface controller having an integrated power supply. The integrated power supply includes an AC to DC power conversion and voltage reduction component. The motor controller and the interface controller receive line voltage electrical power without the need for an external transformer.

Motor interface controller having an integrated power supply

A system for wirelessly programming and diagnosing a motor includes a server computer system, a portable electronic device, and a wireless communication device. The server computer system stores motor operating parameters and other motor data that can be accessed by the portable electronic device over a wireless communication network for identifying a suitable replacement motor for an unserviceable motor. The server computer system also generates motor programming instructions for programming the replacement motor to emulate the unserviceable motor. The portable electronic device wirelessly transmits the motor programming instructions to the wireless communication device for storing the motor programming instructions on a memory of a controller of the replacement motor so that the replacement motor will emulate the unserviceable motor.

Systems and methods for selecting and wirelessly programming a motor

A method of correcting fluid flow offset for an uncharacterized fluid handling system including a motor. The method includes running the motor at a reference fluid flow demand using generic coefficients, and changing fluid flow demand from the reference fluid flow demand until the motor signals a power limit condition. When the motor signals the power limit condition, the fluid flow demand is noted. The operational fluid flow demands are scaled by a ratio of the noted fluid flow demand to the reference fluid flow demand.

Flow control for fluid handling system

Systems and methods for detecting various system conditions in a fluid delivery system (such as an HVAC system) based on a motor parameter are disclosed. Embodiments of the present invention relate to detecting: filter condition, frozen coil condition, register condition, energy efficiency, system failure, or any combination thereof. Embodiments of the present invention relate to detecting fluid delivery system conditions based on motor parameters including system current, system power, system efficiency, motor current, motor power, motor efficiency, and/or a change (or rate of change) in motor parameters. Techniques for responding to a clogged filter and a frozen coil are also disclosed. Also disclosed are techniques for characterizing a fluid delivery system off-site, prior to system installation.

System and method for detecting fluid delivery system conditions based on motor parameters

A latching valve for a fluid system including a valve housing, ported body chamber, and valve lids to control fluid flow between the ports, the valve lids being actuated by a moveable springloaded armature which, in turn, is controlled by a solenoid coil and readily replaceable permanent magnet which acts independently of the solenoid coil during latching operations.

Latching valve for a fluid system

A three-way control valve structure for a variable fluid system including first and second valve inlet ports and a valve outlet in a ported chamber with control means to operate valve lids for the valve inlet ports to close such inlet ports in response to a preselected condition in the variable fluid system.
