2.3.3 Current
The maximum supply currents required by the SSM23Q/IP are shown in the charts below at
different power supply voltage inputs. The SSM23Q/IP 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.
