Microstepping driver JVL

The SMD41/42 series of micro and mini-step drivers is available in 13 different models, with supply voltages from 15VDC to 160VDC, 3, 6 and 9 Amp models, full- half-, mini- and micro-step resolutions that can be changed by dipswitch, up to 25000 step/revolution, and more.

The 160V driver, SMD42 is physically similar to the popular SMD41 mini-step driver, but is intended for high-velocity, high-torque applications. The SMD42 can be powered by a 160VDC supply (compared to 80VDC for the SMD41). This yields up to double the torque at velocities over 500RPM. Heat generation is kept to an absolute minimum through the use of the latest MOSFET technology.

Together with JVL step motor MST 340-342, the 160 V version, SMD42, achieves a remarkable torque of 7-8Nm even at high velocities.
