    Abstract: A coaxial stack of laminations for a stator of an electrical machine uses laminations that are substantially identical and in direct abutment with one another. Each of the laminations has an outer periphery and an inner periphery with the outer periphery being defined by an array of outwardly projecting pins and the inner periphery being defined by an array of inwardly projecting teeth. The outwardly projecting pins cooperate with a jacket surrounding the stack to provide a cooling space through which cooling liquid flows while the teeth provide spaces therebetween for receiving for receiving stator windings. The number of pins (npin) is proportional to the number of teeth (nth) according to the relationship (2K+1)/(2Kth) times the number of teeth (nth), where K is a selected integer number and Kth is the number of teeth past which each lamination is rotated with respect to adjacent laminations so that spaces between the teeth of adjacent laminations are aligned.

    Abstract: A multiple DC-to-AC inverter system, which is suitable for an electric or hybrid vehicle application, includes a plurality of inverters controlled by a single controller. One example embodiment includes four three-phase inverters driving one six-phase motor, where the output of the first inverter is coupled to the output of the fourth inverter and the output of the second inverter is coupled to the output of the third inverter. In response to the failure of an inverter, the drive signals to the inverter that is coupled to the faulty inverter are updated such that the partner inverter can remain active without being driven into an over-current condition.

    Abstract: A control system and method for use in controlling a torque-controlled permanent magnet synchronous motor drive. A slew-rate limiter processes an input torque command to produce a modified torque command that is input to the motor drive. A controller is coupled to the slew-rate limiter and the motor drive for dynamically limiting the input torque command applied to the motor drive and its rate of increase. The slew rate limiter processes an applied torque command to output a modified torque command that is applied to the motor drive. Current control error signals are output by the motor drive. The RMS value of the current control error signals is computed. The RMS value is compared to low and high thresholds. If the RMS value is greater than the high threshold, the modified torque command is reduced until the RMS value is less than the high threshold. If the current control error signal is greater than the low threshold and less than the high threshold, the modified torque command is not increased in absolute value even if the input torque command is increasing in absolute value. If the RMS value is less than the low threshold, no change is made to the input torque command.
