Abstract: A mover for an independent cart system includes a drive member for a linear drive system, a power source configured to supply electrical power to at least one device mounted on the mover, and a mounting plate secured to the mover. The mounting plate is configured to selectively receive one of multiple fixtures. The mounting plate includes at least one electrical connector configured to engage a complementary electrical connector on each of the fixtures, at least one connector configured to engage a complementary connector on each of the fixtures to positively retain each of the fixtures to the mounting plate, and a control circuit operative to either transfer at least one control signal to or receive at least one feedback signal from each of the fixtures.

Abstract: A system for distributing DC bus voltage and control power to multiple motors includes a rectifier front end supplying a DC bus voltage and a DC control voltage. Both the DC bus voltage and the DC control voltage are distributed via a common set of conductors. Diodes are operatively connected between the DC control voltage and the common set of conductors. The diodes allow forward conduction of the DC control voltage and distribution of control power to distributed devices when the DC bus voltage is not present. Once the DC bus voltage is present, the diodes block conduction of the DC control voltage. Each of the distributed devices are configured with an internal power supply that is operative to generate an internal control voltage from either the DC control voltage or the DC bus voltage.

Abstract: A motor having a circuit board including at least two MEMS sensors. The circuit board is mounted within a housing of the motor using the same fasteners as an encoder of the motor. Mounting the MEMS sensors to the circuit board simplifies assembly of the motor and standardizes the positioning of the MEMS sensors within the housing, while the overall motor footprint is unaffected.

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.

Abstract: A motor includes a brake diagnostics system with sensors to assess the brake assembly condition. Acoustic or other vibration sensors provide vibration data that is compared to known vibration spectrum data to compare the condition of the brake assembly to a properly functioning brake assembly. The brake diagnostics system monitors current flow in the brake coil to assess the condition of the brake assembly. The sensed brake coil current is compared to known coil current spectrum data to compare the condition of the brake assembly to a properly functioning brake assembly. The voltage input to the brake coil is varied depending upon the current sensed in the brake coil to minimize heat in the brake coil. The motor also includes a resilient layer of thermally conductive material located between the brake assembly and the housing that provides a continuous, uninterrupted thermal pathway between the brake assembly and the motor housing.

Abstract: The present disclosure is directed to an integrated drive module assembly with vibration-based anomaly detection. The integrated drive module assembly may include a motor coupled to a drive module. The drive module may provide electric power to the motor for operation. Moreover, the drive module may provide control signals to control operations of the motor. The drive module may include an accelerometer and a processing circuit. The processing circuit may determine baseline vibration profiles of the motor during operation using the accelerometer. Subsequently, the processing circuit may determine anomaly conditions of the motor based on comparing the vibrations of the motor with the baseline vibration profiles. Accordingly, the integrated drive module assembly may facilitate performing countermeasures with low latency based on detecting the anomaly conditions using the accelerometer when the drive module is coupled to the motor.

Abstract: A communication module mounted to a motor provides for communication between a motor controller and a motor or between the motor controller and devices mounted on or proximate to the motor. The communication module may be configured to accept signals from various different encoders and/or load devices mounted on or proximate to the motor. The communication module receives a position feedback signal from a primary encoder interface and is configured to transmit the data to the motor controller at a periodic update rate. The communication module also receives feedback signals from at least one additional device and transmits the data to the motor controller. The communication module synchronizes its periodic update rate with the motor controller such that the position feedback signal may be utilized to control operation of the motor. The additional feedback signals may be communicated at the same or differing update rates.
