  • Publication number: 20200358340
    Abstract: 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.

  • Patent number: 10746590
    Abstract: 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.

  • Patent number: 10717365
    Abstract: A controller for an independent cart system simplifies programming and automatically adapts operation each mover travelling along a track. The controller includes a configuration table defining segments of the track, which includes a maximum velocity and/or a maximum acceleration for each mover within the segment. A motion command for a mover commands motion across multiple segments between the starting point and the ending point. As the mover travels, the controller receives a position feedback signal corresponding to the present location of the mover. The controller obtains the maximum velocity and/or maximum acceleration for the mover corresponding to the segment in which it is located. The controller automatically adjusts the speed and/or acceleration of the mover along the segment in which it is presently located. As the mover transitions between segments, the controller automatically adjusts the speed and/or acceleration according to the new segment in which the mover is located.

  • Patent number: 10720864
    Abstract: An improved system and method for monitoring operation of movers in an independent cart system reduces the required communication bandwidth for monitoring operation of movers in a system where control is distributed among multiple controllers spaced along the track. As the mover is travelling along the track segment, each distributed controller monitors at least one operating characteristic of the mover. As a mover travels along the track, each distributed controller transmits the operating characteristic to a successive distributed controller, such the monitored operating characteristic is transmitted along the track as the mover travels along the track. At a reduced rate or upon request from a central controller, each distributed controller may transmit the status of a mover present on the corresponding track segment controlled by that distributed controller to the central controller.

  • Patent number: 10488282
    Abstract: An improved system for monitoring drive members in a belt-driven application during installation and during operation and for detecting common failure modes in belt-driven equipment is disclosed. Sensors are positioned within or proximate the motor housing to detect vibrations on the belt or in the electric machine. The vibration signals are used to monitor operating conditions and/or to identify the failure modes in belt-driven equipment. The vibration signals may be used, for example, to determine tension on a belt, detect either a static or dynamic force applied along the belt, a misalignment between a pulley and the belt, or a shock load applied to the belt during operation. By monitoring the various operating conditions of the belt-driven equipment, a controller may identify an existing failure mode or predict a premature failure mode.

  • Publication number: 20190349456
    Abstract: 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.

  • Patent number: 10442637
    Abstract: A linear drive system provides a combination of distributed control to increase the number of movers which may be supported in the system and centralized control to reduce the separation distance between movers by grouping movers together and placing a reference mover of the group under central control with remaining movers of the group under distributed control. In addition, in precise working locations, or “synchronization zones,” each of the movers can be temporarily placed under central control to further reduce the separation distance and allow improved coordination with industrial processes or machines in the system.

  • Patent number: 10284121
    Abstract: An IPM motor in which the absolute position of the rotor may be determined is disclosed. The IPM motor includes asymmetries in both the rotor and the stator. The rotor includes an asymmetrical pole configuration for one of the pole pairs in the rotor, and the stator includes a different number of turns for each winding of one phase of the motor. The different number of turns on each winding causes a different magnitude of flux to be generated with each winding. The flux interacts with the asymmetrical pole pair to identify to which winding the asymmetrical pole is proximate. A position sensing routine identifies an angular position with respect to each winding. The position sensing routine, in combination with the flux interaction between the windings and the asymmetrical pole provide an absolute position of the rotor within the IPM motor.
