Abstract
The present application relates to a motor control technology, and in particular to a start-up device for a DC motor, a motor system comprising the start-up device, a method for reducing DC motor start-up current and a computer-readable storage medium with a computer program stored thereon for implementing the above method. The start-up device for a DC motor according to one aspect of the present application includes: a switching element connected in series within a circuit comprising the DC motor and a DC power supply; and a control unit configured to cause the switching element to periodically switch between an ON state and an OFF state in a predetermined time interval to reduce the peak value of a start-up current flowing through the DC motor, and to cause the switching element to maintain the ON state after the predetermined time interval ends.
