Title:
ELECTRONIC CIRCUIT AND METHOD FOR SYNCHRONIZING ELECTRIC MOTOR DRIVE SIGNALS BETWEEN A START-UP MODE OF OPERATION AND A NORMAL MODE OF OPERATION
Document Type and Number:
WIPO Patent Application WO/2014/186119
Kind Code:
A3
Abstract:
A motor control circuit and associated techniques can drive an electric motor in a start-up mode of operation followed by a normal mode of operation. The motor control circuit and techniques can receive a selection signal provided by a user that can select one of a plurality of sets of parameter values that determine characteristics of drive signals applied to the motor during the start-up mode of operation. The motor control circuit and associated techniques can synchronize operation between the start-up mode of operation and the normal mode of operation.
