A control system and method for a plurality of motors utilize one, and only one, motor drive unit that provides power to drive any one of the motors. The system and method also utilize a controller th
Usually in fracturing systems, the fracturing equipment is powered by large diesel motors or by other internal combustion engines. Such engines may be very powerful, but have certain disadvantages. Diesel is more expensive, is less environmentally friendly, less safe, and heavier to transport than ...

1. A gaming device comprising: an actuator configured to accept from a player of a game on the gaming device a number of instances of the game desired to be played in a set, the desired number being greater than one; and at least one non-transitory computer readable medium that stores ...
air conditioning, and refrigeration system is includes one or more variable frequency drives (VFD) controlled by one or more VFD controller, which are configured to provide three-phase power to one or more three-phase AC motors and single-phase power to one or more single-phase AC motors. Th...
An effective open circuit fault diagnosis based on the operative characteristics of the brushless direct motor is shown in [22], which is realized by observing the performance of phase current and other parameters about motors or inverters. Similarly, practical current-based diagnostic algorithms by ...
In the Section 4.3.3, the effect of the total budget on the results is further analyzed. If one charging station corresponds to more than one dummy node, then one charging station can be visited multiple times, which can increase the utilization efficiency of the charging station. Hence, the...
