Device for starting sensorless hybrid motor drive of vehicle e.g. electric bicycle, has digital signal processing unit which comprises sample and hold element, differentiation links and window comparator

摘要

The starting device has a measurement unit that measures armature current of a motor (4), a digital signal processing unit which processes the current signals, and an interface for motor control. The digital signal processing unit comprises a sample and hold element, differentiation links (13,14) and a window comparator (15). An independent claim is included for method for starting sensorless hybrid motor drive.
