The DM542 is one of the best value-for-money hybrid stepper motor drivers on the market. Designed to drive stepper motors with outside diameters of between 42mm and 86mm at up to 4.0A phase current. By utilizing a similar circuit to typical servo control methods, the DM542 runs smoothly at both high and low speeds – with little to no noise or vibration.
One of the top features of this stepper motor driver, when compared to more affordable alternatives like theTB6600, is that it maintains a high torque regardless of the speed at which it’s running. Additionally, this enhances the positional accuracy as well, making it ideal for professional applications within machines such as 3D printers, CNC milling machines, and other machines with numerical control devices.
The DM542 also offers a semi-flow function, which automatically reduces the current down to 70% of the output current. This activates when the driver receives no pulse signals for 500ms, and essentially acts as a “semi-sleep” mode, to reduce power usage and prevent possible overheating between uses. Be sure to install this stepping motor driver away from other heating devices and allow for 20mm of open space surrounding the unit for effective heat dispersion.
