Clutches and brakes protect delicate
materials
The MagPowr range of magnetic particle clutches and brakes provide excellent characteristics for precise web tension control - especially where the material is delicate.
The MagPowr range of magnetic particle clutches and brakes, available exclusively from Warwick based Motion Drives and Controls, provide excellent characteristics for precise web tension control - especially where the material is delicate The simple yet effective operating principle of the MagPowr clutch involves coupling a drive cylinder to an output rotor with magnetic particles that are activated and controlled with current via a series of coils arranged at the periphery of the assembly

Industrial screwjacks lift and position
Competitively priced industrial screwjacks come with a comprehensive choice of options and accessories to suit specialised applications, including low backlash versions.
As current is increased, the field strength increases the torque capacity of the clutch.
The benefits of a magnetic coupling system include constant torque throughout the speed range - even at zero speeds.
Torque is fully proportional to current and the smooth motion is repeatable, guaranteeing consistent results.

Factory-trained staff carry out a complete assessment of the condition of the safety or sliding chuck at the customer's site.
As long as the load torque requirements are less than the torque setting in the clutch, the drive and load are 100 % coupled with no slip.
Slip will occur when the clutch torque is commanded to a level equal or less than the load requirements.
The silent operation, long life expectancy and dependable torque transmission characteristics of the magnetic particle clutch make it perfect for cycling and overload applications particularly for web tension control on thin or delicate materials that tend to stretch under load and for most nonwoven materials.
The complete range of MagPowr clutches and brakes covers input speeds between 34rev/min and over 3000rev/min with torque ratings from 1 to 135Nm.
Clutches and brakes from simple open-loop unwind to fully integrated closed-loop tension control systems are available in a variety of mounting configurations and with cooling options to improve torque transmission or braking capacity and duty cycle are available.
A new 175-page "Designers notebook" is available from Motion Drives and Controls covering an invaluable applications guide and full specifications for the complete range of magnetic particle brakes and clutches available from MagPowr.
The guide also covers sising formulae and full details of other MagPowr web tension and torque control products including tension controls, load cells and readouts, pneumatic brakes and permanent magnet clutches and brakes.
ISO9002 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.
