Integrated Drive Motor Power Interface
US Patent:
2013011, May 16, 2013
Filed:
Oct 26, 2012
Appl. No.:
13/661566
Inventors:
Mark Alan Gries - Wauwatosa WI, US

International Classification:
H02P 29/00, H02K 11/00, H02H 7/08
US Classification:
318490, 318494, 361 31
Abstract:
An integrated drive motor (IDM) power distribution architecture utilizes an IDM power interface module (IPIM) to create a control voltage that is distributed to all the IDMs in a network. This power distribution may be accomplished along a hybrid cable, for example, that includes both signal conductors and power conductors. The IPIM is capable of detecting short circuits and/or overload conditions and disabling the power supply to the IDMs. Additionally, a second power supply may be utilized in the IPIM such that when the power supply to the IDMs is deactivated, the IPIM may remain functional, for example, to report one or more fault conditions to the user. Additionally, this reporting of fault status may be accomplished via a user display integrated with or coupled to the IPIM.
System And Method For Managing Dc Link Switching Harmonics
US Patent:

International Classification:
H02P 27/00
US Classification:
3184003
Abstract:
A distributed motor drive system includes a power management module and multiple inverter modules integrated with the motors and located on a machine or process remote from the power management module. The power management module distributes DC voltage and command signals to each of the inverters, where the DC voltage is distributed between modules via a DC link cable. The integrated inverters execute switching routines to convert the DC voltage to an AC voltage suitable for controlling the motor. Each of the power management module and the inverters includes a portion of the DC bus. The current on the DC link cable is monitored and general bus utilization as well as overload conditions are reported.

Abstract:
A distributed motor drive system includes a power management module and multiple inverter modules integrated with the motors and located on a machine or process remote from the power management module. The power management module distributes DC voltage and command signals to each of the inverters. The DC voltage is distributed between modules via a DC link cable. The integrated inverters execute switching routines to convert the DC voltage to an AC voltage suitable for controlling the motor. Each of the power management module and the inverters includes a portion of the DC bus capacitance. The distributed motor drive system also includes a link inductance between the power management module and the inverters to limit the amount of reactive current generated by the inverters.
