  • CONVEYOR CAROUSEL WITH DISTRIBUTED DRIVE SYSTEM
    Publication number: 20080296130
    Abstract: A carousel according to the invention uses a number of smaller, less expensive drive units at different locations along the carousel path in place of a single larger drive unit of comparable capacity. Closed loop control according to the invention allows individual drives to be de-energized when the power requirements do not demand their usage. When not energized, the drives may be disengaged from the chain, such as by means of a linear actuator as described hereafter. Benefits of such a system include reduced mechanical costs, longer drive life, better redundancy/higher availability, correct drive power, lower energy use, closed loop system monitoring and reduced collateral damage.

  • METHOD OF STARTING A SYNCHRONOUS MOTOR WITH A BRUSHLESS DC EXCITER
    Publication number: 20080258672
    Abstract: A starting method and system for a motor where the motor may be started as an induction motor by applying a magnetizing current to build flux through the stator, with the field current set at the maximum permissible exciter stator current (i.e., the current that will cause rated no-load current in the main field at the transition speed). The motor stator currents will be maintained at a value that allows the motor to generate sufficient breakaway torque to overcome any stiction. At a specific transition speed or after a period of time, the drive will initiate a transition from induction motor control to synchronous motor control by removing the initial magnetizing current, and a field current is then applied to the motor through the DC exciter. Once this transition is completed, the drive may ramp up to the desired speed demand.
