AHM Model
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 suit, the transmission ratio can be adjusted without changing the distance between the drive and driven shafts.This model integrates the AHS unit with the motor. It offers a comprehensive range of control functions.
