Current
e maximum supply current required by the SWM24 is shown in the chart below with dierent power supply voltage
inputs. You will note in the chart that the Drive+Motor does not draw as much current as the motor itself. at’s because
the SWM24 uses switching ampliers, converting a high voltage and low current into lower voltage and higher current.
e more the power supply voltage exceeds the motor voltage, the less current you’ll need from the power supply.
Also note that the current draw is signicantly dierent at higher speeds depending on the torque load to the motor.
Estimating your current needs may require a good analysis of the load the motor will encounter.
