They are suitable for driving 2-phase and 4-phase hybrid stepping motors. By using advanced bipolar constant-current chopping technique, they can output more speed and power from the same motor compared with traditional drivers, such as L/R drivers. Its 3-state current control technology allows coil current to be well controlled with relatively small current ripple, therefore less motor heating is achieved. ** Free Expedited / Express Shipping. ** ** Free Return (30 Days). ** May have some marks and scratches on item because item is old stock or used condition.
