2.3.3 Current
The maximum supply currents required by the SSM23C are shown in the charts below at different
power supply voltage inputs. The SSM23C power supply current is lower than the winding
currents because it uses switching amplifiers to convert a high voltage and low current into lower
voltage and higher current. The more the power supply voltage exceeds the motor voltage, the
less current will be required from the power supply.
It is important to note that the current draw is significantly different at higher speeds depending
on the torque load to the motor. Estimating how much current is necessary may require a good
analysis of the load the motor will encounter.
