Product Description
The SD-2H044MA is an economical micro step driver. It is suitable for driving 2-phase 4-phase hybrid stepping motors .By using the advanced bipolar constant-current chopping technique ,it can output more speed and torque from the same motor, compared with traditional drivers ,such as L/R drivers .Its 3-state current control technology allows coil currents to be well controlled and with relatively small current ripple, therefore less motor heating is achieved.
