ACW Model | Miki Pulley

In belt-driven power transmission systems, variable-pitch pulleys are installed on both the drive shaft and the driven shaft. By forcibly changing the pitch on the drive side and causing the driven side to follow, the transmission ratio can be adjusted without changing the distance between the drive and driven shafts.This model incorporates an electromagnetic clutch and electromagnetic brake into the ANW model. It enables control of the output drive.
