Patent ID: 7345859

Claim:
A method of starting a motor, the method comprising the steps of: (a) connecting a battery to input terminals at an electronic unit controlling the motor, thereby supplying a current to the electronic unit from the battery, the electronic unit ensuring that the supplied current does not exceed a predefined maximum current, I max ; (b) at least substantially continuously measuring an input voltage, V input , on the electronic unit input terminals, and comparing V input to a predefined minimum voltage, V min ; (c) in case V input becomes smaller than V min , stopping the motor and waiting for a predefined time interval; (d) lowering the maximum permitted current level, I max , to be supplied from the battery to the electronic unit; and (e) repeating steps (b) through (d) until it is obtained that V input ≧V min and the motor is no longer in start-up mode.
