METHOD FOR COMPENSATING MOTOR PHASE OF ELECTRIC FEEDER

摘要

A method for correcting a motor phase of an electric feeder is provided to prevent motion of a motor in driving an electric feeder by controlling a phase of a driver according to an input phase of the motor. An input phase of a motor is stored to a memory part in the power off of an electric feeder. The memory part is a nonvolatile memory device. A power source is again applied to the electric feeder(S200). A driver is disabled(S210). A phase of the driver initialized in the power on of the electric feeder is controlled according to the input phase of the motor stored to the memory part(S220). The driver is enabled(S230). A current is supplied to the motor according to the input phase of the motor in the power off of the electric feeder.
