Is the phase current smaller or larger than the bus current

The current that flows through the phases of a motor is lower than the current flowing through the DC bus input because the servo drive behaves as a step-down DC/DC converter. Ignoring inefficiencies, commutation and commutation details (see below), the product of "input voltage x input current" should be equal to the "output current x effective motor voltage". The power is given by a DC power supply. This depends on. In a star connection, the Line current is equal to the phase current, or IL = IPh In a delta connection, the line current is √3 times of phase current or IL = √3IPh What is Phase Current? The flow of current through any one component of the three-phase system to load is called ...
