Patent number: 11767174Abstract: A contactless monitoring system detects operating performance of movers in an independent cart system. A contactless sensor is provided on an actuator to automatically track a mover as it travels along the track. The sensor includes a transmitter configured to transmit a signal and a receiver configured to receive the signal after it is reflected off the mover. The actuator may be configured to mover the sensor in a single axis or in multiple axes of motion. As a mover travels along the track, the sensor transmits a signal towards the mover and detects the signal after it has been reflected off the mover. A controller may synchronize motion of the actuator with motion of the mover, such that the sensor may continually transmit the signal off the mover for at least a portion of the travel by the mover along the track.Type: GrantFiled: June 23, 2021Date of Patent: September 26, 2023Assignee: Rockwell Automation Technologies, Inc.Inventors: Jadav Das, Robert H.

Patent number: 11581838Abstract: A system for wirelessly transmitting power between a track and independent movers in a motion control system includes a pick-up coil provided proximate to the magnets on the movers. The fundamental component of the voltage applied to the drive coils interacts primarily with the magnetic field generated by the permanent magnets on the movers and not with the pick-up coil. Consequently, the pick-up coil does not interfere with desired operation of the movers but rather, interacts primarily with the harmonic components and has current and voltages induced within the pick-up coil as a result of the harmonic components. The energy captured by the pick-up coil reduces the amplitude of eddy currents on the mover. After harvesting the harmonic content, the pick-up coil may be connected to another circuit on the mover and serve as a supply voltage for the other circuit.Type: GrantFiled: April 13, 2021Date of Patent: February 14, 2023Assignee: Rockwell Automation Technologies, Inc.Inventors: Xikai Sun, Jadav Das, Tracy M. Clark, Robert H. Schmidt, Neil R. Bentley

Patent number: 11211851Abstract: A motor drive utilizes redundant current feedback to monitor force being produced by a motor and to provide safe limited force producing operation of the motor. A first set of current sensors provides a first current measurement, and a second set of current sensors provides a second current measurement. The two current measurements are provided to two diverse force producing calculations, where each force producing calculation provides a value of the force produced by the motor. The motor drive compares the output of the two algorithms to each other. If the output of the two force producing calculations is the same, within an acceptable band, the controller continues operating as commanded. If the output of the two force producing calculations differs beyond the acceptable band, then the controller may generate a fault message provided back to a central controller, stop operation of the motor, or a combination thereof.Type: GrantFiled: May 10, 2019Date of Patent: December 28, 2021Assignee: Rockwell Automation Technologies, Inc.Inventors: Arun K.

Publication number: 20210184545Abstract: A contactless Ethernet communication technique adapted for communication between a rotor and a stator in a rotating machine is disclosed. Power is supplied to the rotor via a contactless power transfer system. The power energizes a transmitter on the rotating machine to generate data packets in an industrial protocol, such as EtherNet/IP, for transmission on an Ethernet physical link layer. A rotary coupler, such as a digital rotary transformer, is provided between the rotor and stator, where a rotating member on the rotor is communicatively coupled to a stationary member on the stator. The data packet is transmitted in the industrial protocol via the rotary coupler. A receiver on the stationary side may receive the data packet where some initial processing may be performed and the data retransmitted. Alternately, a network device may receive the data packet and pass it along the industrial network to a remote device for further processing.Type: ApplicationFiled: December 13, 2019Publication date: June 17, 2021Inventors: Xikai Sun, Robert H.

Patent number: 10938967Abstract: The subject matter disclosed herein describes a switch embedded in a motor controller and a network protocol executing on the switch to provide communication between devices connected to the motor controller in a motor drive application. The embedded switch is configured to communicate via separate ports with an external controller, a network interface for the motor controller, additional motor controllers, and with the motor or other devices mounted on the motor. The network protocol includes a first tier for data that requires deterministic delivery at a high data rate, a second tier for data that requires a high delivery rate but is also tolerant of some variation in delivery time, and a third tier for data that may be delivered at a slower data rate. The embedded switch receives data at any port, identifies the communication tier to which the data belongs, and delivers it to another port accordingly.Type: GrantFiled: July 26, 2019Date of Patent: March 2, 2021Assignee: Rockwell Automation Technologies, Inc.Inventors: Dayin Xu, Zhenhuan Yuan, Robert H.

Patent number: 10879831Abstract: A system and method for real-time detection of anomalies in a motor drive includes a controller receiving one or more signals corresponding to real-time operation of a controlled system. The controller samples the real-time signal during operation of the controlled system and maintains a moving window of the sampled data. A signature of the sampled data within the moving window is then generated. Each signature corresponds to operation of the controlled system within the period of time defined by the moving window. An identifier and a number of occurrences of each signature may be stored with the signature. An initial table of expected signatures may be generated, for example, by executing a training, or learning, period within the control system. The controller compares each real-time signature against the table of expected signatures to detect the occurrence of an anomaly.Type: GrantFiled: September 26, 2019Date of Patent: December 29, 2020Assignee: Rockwell Automation Technologies, Inc.Inventors: Gerry M.

Patent number: 10746590Abstract: The subject matter disclosed herein describes a method and system to monitor and identify vibrations in a rotational mechanical system. Various fault conditions in a rotating machine operating at variable speeds may be identified, at least in part, by identifying the multiple of the fundamental frequency, or order, at which the vibration occurs. The orders of vibration present in a measured vibration signal may be determined by finding an order spectrum of a measured vibration signal in the position domain. A fault vector is generated from the order spectrum that identifies the magnitude of each order of vibration present in the measured vibration signal. The fault vector may be plotted on a radar chart to provide a visual indication of the type of fault present in the mechanical system. Evaluation models for each fault determines a probability and magnitude for each fault condition being present in the sampled vibration signal.Type: GrantFiled: September 29, 2017Date of Patent: August 18, 2020Assignee: Rockwell Automation Technologies, Inc.Inventors: Linglai Li, Zhenhuan Yuan, Kun Wei, Robert H.
