The flow chart for industrial machines is similar to the cash machine. It should be remembered that stepper motors are for precise positioning control and if they have micro-stepping capability, they can also be used to reduce the vibration in the motors. Brushed DC motors and their drivers are typically less expensive than their stepper counterparts. Therefore if precise positioning is not critical, this type of motor is usually chosen. Some of these H-bridge drivers support more than one channel, be certain to verify how many channels are needed.
