... drives actuators electric motors friction commutation commutators Theoretically, the actuator is uncontrollable at the critical angle, θ c . An implementation consideration is that there is actually a neighborhood around θ c where K t ( θ ) is very small...

... to specific targets. In the first stage, it is common to target the mean and variability of performance when fixing the values of platform variables. This paper contributes three new methods for platform development. The new methods are demonstrated on an electric motor example from the platform design...

...L. W. Tsai; G. Schultz This paper presents a motor-integrated transmission mechanism for use in parallel hybrid electric vehicles. The transmission can provide five basic modes of operation that can be further classified into sixteen sub-modes: one electric motor mode, four engine modes, four...

.... In those applications the problems are partially coupled. In designing an electric motor, the case study in this article, the problem is fully coupled: in order to design the motor, power and torque ratings must be assumed, which in turn must be related to the power and torque that the controlled motor...

... of electric motors is developed and compared against previous results. We find that the PFPF enables us to properly balance commonality and performance within the product family through the judicious selection of the common parameters that constitute the product platform and the scaling parameters used...

... and a microprocessor-based controller are needed to manage the power flow among the various power sources. The transmission mechanism described in this paper can provide a parallel hybrid with thirteen clutching conditions that can be grouped into five major modes of operation, namely, electric motor mode, power mode...
