TH3606MA(B) is a constant torque driver with microstep. Single power input, voltage range from DC16-60V, which can match with 3 phase hybrid stepper motors whose rated current is under 5.8A, flange size range from 42-86mm. This driver uses bipolar constant current chopper control runs smoothly, hardly has any noise. High voltage input makes it possible to enhance the motor speed and output torque. Further more, if the pulse output stops for 100ms, phase current will be automatically cut by half, which prevents the motor from over-heat. By microstep setting, resolution of the motor can be enhanced. The microstep can be set to 60000 pulse/rev.
