Stepper Motor Driver – PoStep25-32
The PoStep25-32 is a high-performance, cost-effective stepper motor driver to implement intelligent stepping motor control. The driver incorporates advanced architecture and surface mount technology to achieve an exceptional power density and low heating. Low footprint, high power density, and robust design are key for reliable stepper motor driving.
PoStep25-32 is high performance and low-cost bipolar stepper motor driver
The PoStep25-32 is a high-performance, cost-effective bipolar stepper motor driver. Firstly the driver incorporates advanced architecture and surface mount technology. Secondly copper on the printed circuit board is 2 times thicker than in most Printed Circuit Boards. In conclusion, PoStep25-32 has a state-of-the-art thermal design. Thick copper and additional heatsink quarante the best thermal performance and low heating. Low footprint, high power density, and robust design is a key for reliable bipolar stepper motor driving. There are 4 microswitches on the PoStep25-32. Thus, fast and reliable settings for micro-steps and decay. Moreover switching between mixed and fast decay and settings between full step and 32 micro-step can be made.
Many bipolar stepper motor drivers are linear what is the reason for heating. However, PoStep25-32 is a chopping bipolar stepper motor driver. Therefore it has much better energy efficiency and lower heating.
It can drive bipolar stepper motors at a maximum of 2,5A. Besides Nema17, also some Nema23 stepper motors can be driven.
