Variable speed AC drives from Parker Hannifin

Now offered in five different frame sizes, the AC30 drive devices provide users with high levels of control, from simple open-loop pumps and fans through to closed-loop process line applications. The units give comprehensive and cost effective control of either AC induction or permanent magnet servo motors. The extended range now includes an optional pulse encoder feedback module, which allows users to run the drive in closed-loop control rather than open-loop. This provides optimisation in highly dynamic applications, such as winding and cranes, where the speed or torque of the motor requires accurate control. Featuring integrated energy monitoring functionality, the AC30 series facilitates the matching of motor speed to varying application demands, thus supporting the reduction of energy consumption. Parker Hannifin says this not only saves money, but also extends the mechanical life of motors, pumps, fans and ancillary equipment such as ducting or pipework.
