CHAPTER 24 STEPPING MOTOR CONTROLLER
24.1
Outline of Stepping Motor Controller
The Stepping Motor Controller consists of two PWM Pulse Generators, four motor
drivers and the corresponding Selector Logic. The four motor drivers have high output
drive capabilities and they can be directly connected to the four ends of two motor
coils. The combination of the PWM Pulse Generators and Selector Logic is designed to
control the rotation of the motor. A Synchronization mechanism assures the
synchronous operations of the two PWMs. The MB90390 series provides 6 separate
Stepping Motor Controllers.
