This paper shows that winding drives in combination with a continuous variable transmission (CVT) will lead to reduced rated power as well as an increased efficiency of the electrical drive. First practical experiments with imitation of a winding operation were performed to verify the theoretical investigations.
The paper presents an optimization design of an in-wheel BLDC motor for a kick scooter. The optimization is performed using a genetic optimization tool combined with a FEM commercial software. The new contributions of the paper are: (i) introduction of three operating modes for which the motor is optimized with a reduced number of FEM simulations and (ii) new approach to simultaneously maximize the...
Servo drives comprise a significant potential of energy saving which has not been considered sufficiently up to now. Simple changes in the motion control of energy optimal and jerk limited motions can be implemented which lead to a reduced acceleration rms-value and slightly increased maximal acceleration. The resulting reduction factors for dimensions and moved masses lead even to further savings...
