NPAD10BF drive modules output up to 1.2A per phase (peak) current, offer an input voltage range from 12 to 30V DC and can drive bipolar stepper motors with a 1/16 microstepping resolution.
The NPAD10BF from Micromech is an easy to mount and simple to connect microstep drive that fits onto the back of NEMA size 17 (42mm square) motors.
The solution has all the advantages of a piggyback drive without the potential problems of 'built in' drives.
These drivers are a constant current (chopper) type driver board with opto-isolated inputs.
They are small, easy to use and interface, yet powerful enough to support most light instrument positioning applications.
NPAD10BF drive modules output up to 1.2A per phase (peak) current, offer an input voltage range from 12 to 30V DC and can drive bipolar stepper motors with a 1/16 microstepping resolution.
This results in a theoretical axis resolution of 3200 microsteps per revolution.
Such a resolution can result in a sub-micron positioning capability if a 2mm pitch or less lead-screw is used.
The 41.3 x 43.74mm NPAD10BF has mounting holes to give designers the option of direct connection to the motor.
This is useful for integrating the driver with the stepping motor or where space is limited These drives are also compatible with two-phase stepping motors such as the Nippon Pulse PF/PFC tin can rotary stepper motors as well as their PFCL Linearstep motors.
