Magpowr helps maintain precise tension control

MAGPOWR reverse current feature helps maintain consistent and precise tension control for magnetic particle clutches and brakes, for unwind, rewind and intermediate tension control applications

Magpowr magnetic particle clutches and brakes, available exclusively in the UK from Warwick based Motion Drives and Controls, provide a very precise yet simple solution for demanding web tension and torque control applications.

For even greater control at near zero torque, all Magpowr power supplies include a reverse current feature that helps to remove the inherent drag torque caused by small amounts of residual magnetism within the mechanism.

This standard feature ensures the widest possible torque range and is proven to maximise finished quality and decrease material wastage in web tensioning applications, particularly for nonwoven and delicate materials.

Magpowr clutch and brake units cover input speeds between 34 rpm to over 3000 rpm with torque ratings from 1 Nm to 135 Nm.

Applications range from simple open-loop unwind to fully integrated closed-loop tension control systems with clutches and brakes available in a variety of mounting configurations.

Cooling options to improve torque transmission, braking capacity and duty cycle are available.

Tension controls include the compact Cygnus, providing a range of advanced features including web break detection and out-of-round roll compensation.

The comprehensive Versatec tension controller includes modes for ultrasonic tension control, dancer control, free loop, and ranger applications.

Other dedicated controllers are available for dancer/follower applications and the complete range is supported with load cells and readouts.

A full range of matching power supplies includes the DIN Rail mounted PS-90.

With a current regulated voltage range of -3.6 VDC to +90 VDC and four selectable current ranges of 1/8, 1/4, 1/2, and 1 A, the unit may be mounted inside the machine cabinet and manually adjusted by an operator from a remote potentiometer, or can be controlled by a 0-10 VDC input from a Magpowr controller or PLC.

For a very convenient installation solution, this CE compliant, UL and cUL listed product may be fitted inside the Cygnus-E tension controller.

A 24 VDC version (PS-24) is also available.

Other power supply options include card and packaged versions.

All Magpowr power supplies include the reverse current feature ensuring excellent fine control for web tensioning and precise torque limiting applications.

ISO 9002 approved Motion Drives and Controls provides a complete service covering the supply of components through to customised design and on-site installation of turn-key automation systems with a 24 hour, 7 day service backup.
