#* Digital servo drives are practically sophisticated switching step-down voltage regulators, and the torque controller takes care that the current to the motor (and thus the voltage) is correct. | #* Digital servo drives are practically sophisticated switching step-down voltage regulators, and the torque controller takes care that the current to the motor (and thus the voltage) is correct. | ||

#* Considered as a step-down regulator, the digital servo drive transfers power, not current to the motor. Because of this, the PSU's current rating affects maximum power that can be driven into a motor, not maximum current. | #* Considered as a step-down regulator, the digital servo drive transfers power, not current to the motor.

#* In ideal world, e.g. 48 V PSU with 10 A current rating can output 480 W power. If the required voltage to a motor to drive 24 A current is 20 V, the transferred power is the same what the PSU can supply. | #* In ideal world, e.g. 48 V PSU with 10 A current rating can output 480 W power.
