US Patent:
20090033272, Feb 5, 2009
Filed:
Aug 2, 2007
Appl. No.:
11/832762
Inventors:
Craig Winterhalter - Cedarburg WI, US
Robert Harris Schmidt - Germantown WI, US
Arun K. Guru - Germantown WI, US
Assignee:
ROCKWELL AUTOMATION TECHNOLOGIES, INC. - Mayfield Heights OH
International Classification:
G05B 21/02
US Classification:
318650, 318636
Abstract:
Self-sensing feedback functionality for electromechanical actuators/motors is provided for use in operation and/or as a redundant safety mechanism to attain safety certification without adding extra bulk or wiring to the motor. An actuator can be manufactured having one or more saliencies that cause a spatial variance of inductance. A high frequency signal can be injected into the actuator and sampled to determine a current, voltage, or other electrical parameter. The parameter can be evaluated against the known saliencies of the actuator to determine a position of the actuator and/or an associated rotor. Additionally, the position can be evaluated as a function of time to determine a velocity. This can provide an alternative method for operating the electromechanical actuator according to the position/velocity provided. Additionally, this can provide a redundant feedback channel for safety certification without requiring additional actuator parts.

Apparatus For Distributing Dc Bus Power And Control Power Over Common Conductors In A Distributed Dc Bus System

View page
US Patent:
20220329065, Oct 13, 2022
Filed:
Jun 28, 2022
Appl. No.:
17/809497
Inventors:
- Mayfield Heights OH, US
Mark A. Gries - Wauwatosa WI, US
Craig R. Winterhalter - Cedarburg WI, US
Arun K. Guru - Brookfield WI, US
International Classification:
H02J 1/08
H02M 7/12
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.

US Patent:
20190101175, Apr 4, 2019
Filed:
Sep 29, 2017
Appl. No.:
15/720413
Inventors:
- Mayfield Heights OH, US
Arun K. Guru - Brookfield WI, US
Assignee:
Rockwell Automation Technologies, Inc. - Mayfield Heights OH
International Classification:
F16D 66/02
G01M 13/02
F16D 49/02
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.

US Patent:
20190092621, Mar 28, 2019
Filed:
Sep 27, 2017
Appl. No.:
15/716977
Inventors:
- Mayfield Heights OH, US
Michael J. Melfi - Richfield OH, US
Zhenhuan Yuan - Shanghai, CN
John A. Balcerak - Muskego WI, US
Arun K. Guru - Brookfield WI, US
Assignee:
Rockwell Automation Technologies, Inc. - Mayfield Heights OH
International Classification:
B81B 3/00
H02P 1/02
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.

Method And Apparatus For Detection Of Drive Misconfiguration In A Multi-Axis Configuration

US Patent:
20150091486, Apr 2, 2015
Filed:
Oct 1, 2013
Appl. No.:
14/042910
Inventors:
- Mayfield Heights OH, US
Gerry Nagel - Sussex WI, US
Arun K. Guru - Brookfield WI, US
Ryan Jwanouskos - White Bear Lake MN, US
Assignee:
Rockwell Automation Technologies, Inc. - Mayfield Heights OH
International Classification:
H02K 11/00
US Classification:
318490
Abstract:
A system for detecting a mismatch between how a motor drive is connected electrically and how it is configured for operation is disclosed. The motor drive may either be connected in a stand-alone mode to control operation of a motor from an AC source without connection to another motor drive or be connected electrically to other motor drives, for example, in a paralleled mode, shared DC bus mode, or a combination thereof. A parameter identifies the expected electrical configuration of the motor drive. The power transferred to the DC bus is compared to the power transferred from the DC bus in the motor drive. If the difference between the power transferred to the DC bus and the power transferred from the DC bus exceeds a predetermined threshold, the motor drive detects the mismatch between 110W a motor drive is connected electrically and how it is configured for operation.
