New benefits of vector control of hybrid stepper motors with encoder

Nov. 17, 2005
This paper compares the main characteristics of both vector controlled brushless DC motors and hybrid stepper motors according to real industrial applications.
By Kai-Uwe Veregge, Jenaer Antriebstechnik GmbHTHIS PAPER shows that beside the advantages of more power per volume and higher speed of today’s state-of-the-art brushless DC motors, the push in microelectronics gives motor constructions like hybrid steppers a comeback on motion control -- not in the general scene, but in those niche markets where the cost-performance-reliability (CPR) requirements have to be optimized. “There's life in the old dog, yet”.
