Power Supply Selection
A high-torque DC motor requires high current during startup and during high load or irregular load
conditions. The general rule of thumb to make sure your power supply is adequate for a DC motor is to
make sure it can supply the maximum current required by the motor during stall condition. It is also good
practice to have sufficient low
–
ESR decoupling capacitors on the output of the supply before you connect
it to a DC motor drive. This is to make sure that the motor driver does not reset or suffer from variations
in speed due to an insufficient or unregulated supply.
