Figure 2.2.2.14.1 TM4500 variable amperage stepper motor driverThe driver is the last functional portion in the stepper motor drive circuit. It acts toconvert the signal output by the controller and amplifying it to a large enoughcurrent to drive the stepper motor. Without the driver, the signals wouldn’t belarge enough to turn the motor. This unfortunately creates a large amount ofheat that is dissipated through the large heat sink that covers the majority of thedriver circuitry. The driver, like the controller, is very small and doesn’t take upmuch space within the enclosure but must be cooled via a fan so that it doesn’tover heat and malfunction. The dimension specifications are shown below in fig.2.2.2.14.2.73
Figure 2.2.2.14.2 TM4500 dimensionsThe wiring to connect the controller and driver is also very simple because bothproducts were obtained from the same company and are meant to functiontogether. The wiring diagram is shown in fig. 2.2.2.14.3.74
