CW1108 Stepper motor driver, current range: 8A - details see: https://www.machineto.com/cw1108-two-phase-stepper-motor-driver-8a-current-10234599

Performance and features

1. Microstepping control: step motor can be operated and located for 1,1/2,1/4……1/256,1/5,1/10……1/50 origin step angle, so the control accuracy is increased and the defect of rough running and easy to out-of-step operation in low speed is overcome.
2. Smooth-subdivision control: minimum positioning accuracy is still the origin step angle of motor, but smooth-subdivision transition is used between steps to overcome the defect of rough running and easy to out-of-step operation in low speed.
3. High speed and high torque: the slaving voltage of power amplifier is DC140V, so high-torque output is obtained in high speed.
4. New technique: control core consists of Single Chip Microcomputer and programmable array, good control performance; large power IGBT amplifier tube made by Fairchild Co. in USA, strong overload and overheat ability, hard to burnout.
5. High reliability: high integrated level of control circuit, few connecting lines, dust-proof structure, protection of over temperature, over current and under voltage.
