PrimoPal provides two types of stepper motor drives, the analog M series of stepper motor drives and digital DM series of stepper motor drives. The low-cost M series of analog stepper motor drives adopt precise analog current control and are characterized by superior high-speed torque, relatively low stepping noise, and low motor heating. The DM series of digital stepper motor drives are DSP-based innovative products. Their features include super-low stepping noise, anti-resonance, low-speed ripple smoothing, and low motor heating.
