Braking resistor designs and applications
Depending on the application, the addition of a braking resistor to a motor drive system can play a variety of roles, from enhancing safety to reducing mechanical stresses.
The standard WI magnet consists of a laminated core, excitation coil, armature and a mode selector link.
The laminated core and armature are manufactured from high quality steel laminations, to provide the best magnetic properties and to reduce heat and power loss.
The coil is machine wound on to the core, using laquered copper wire to provide the very best performance characteristics possible.
Once this has been done, the magnet is encapsulated in a fire resistant UL approved material to protect and insulate the windings and provide better all round heat dissipation.
The armoured cable running to the magnet both gives protection against accidental damage and acts as an EMC screen.
The WI mode selector link system is a unique feature which enables the WI series to be run in any one of four voltage/frequency combinations, simply by fitting the appropriate selector link.
Using any one of the four available links, the magnet can be quickly and easily configured to operate in any particular commonly used configuration: 200V full wave, 100V full wave, 200V half wave and 100V half wave.
In full wave modes, the resulting mechanical oscillation will be twice that of the mains input frequency, as for every half wave, be it positive or negative, there will be a magnetic impulse.
When controlled to run in half wave modes, the oscillations will run at a rate of half the mains cycle to the magnet.
This gives a coarser feed which is more suited to particular products and applications.
The WI range consists of six versions: from the WI7, which is the smallest, rated at 175VA, up to the WI6, the largest at 2060VA.
Control of the WI magnets is provided by a REOVIB control unit which adjusts the supply voltage and selects the applied frequency.
The REOVIB unit can also monitor and measure the feed system to provide total control of the handling application. Request a free brochure from REO (UK) ...
