One of the main benefits of Parker’s torque motors is to help end users of heavy-duty industrial machinery replace traditional motors and gearboxes with a highly efficient direct-drive system.  Used in conjunction with Parker’s variable-speed drives, the torque motors are to be used with plastics and rubber extrusion machines, as well as with injection moulding, mixing, crushing and winding equipment.  Torque motors are also benefitous by reducing energy and maintenance costs, and as such improve productivity and profitability, and provide greater reliability and overall levels of performance.

In contrast to some high-power machines using AC or DC motors linked to gearboxes to provide the required torque and speed to drive screws, shafts and other associated components, the new Parker TMW series torque motors are based on a proven design of permanent-magnet, brushless servo motor, which produces high levels of torque at low operating speeds.  The noise, unreliability, and high levels of power usage are also eliminated through the use of torque motors.  The Parker TMW series torque motors are easy to install, operate, and maintain. It also has a smaller footprint, can be retrofitted easily and require only minimal maintenance.     

Further torque motor benefits are that Parker’s TMW range features an integrated thrust bearing that can be sized according to the application, as well as an innovative screw extraction mechanism to simplify installation and maintenance, unlike some other torque motors available on the market.  Another Parker torque motor benefit is that it is able to offer both standard and customized mechanical interfaces for shafts and barrels, with the shaft being hollow to improve cooling.  The TMW range can be used with machinery requiring from 1200 up to 22,000Nm of torque and running at speeds of 50-500rpm.  It is estimated that the typical efficiency improvements from a TMW motor and AC890 drive combination is up to 10 per cent better when compared with a traditional gearbox based system.  This is truly awesome benefits when comparisons are made between the Parker TMW series torque motors and other torque motors on the market.
