Torspec has a full range of Eddy Current Brakes. They provide a self-contained,
air-cooled, frictionless means of providing retarding torques for industrial and
process systems. The brakes are available with a full range of control systems
to suit every need from web tension control to dynamometers. They can be
torque-controlled over a wide range and can have speed-responsive systems for
some processes.
Features of TORSPEC Brakes:
· Continuous retarding Torques up to 192 Nm (143 lb-ft)
· Continuous
Braking Speeds up to 6000 rpm.
· A range of 7 sizes*.
· Air-cooled,
frictionless operation-no wears, no routine maintenance; ease installation and
maintenance.
· Belt drive, direct drive or flange-mounted to a gearbox.
· Tacho-generator incorporated for speed control and speed indication.
·
Brakes can be driven in either direction (clockwise or counterclockwise).
Control Systems for TORSPEC Brakes:
· Speed control braking to maintain a set speed.
· Overspeed braking in
association with a suitable control signal.
· "Open loop" torque control
with a stabilization system.
· "Closed loop" torque control from a
transducer signal.
· Cyclic variation of torque, either gradual or step
function.
· Web tension control on reel unwind or capstan.
Typical Applications for TORSPEC Brakes:
· Dynamometers for production and research testing.
· Simulation of dynamic
loading.
· Overspeed braking for over-running loads.
· Unwind web
tension control from stock reel.
· Nip roll or capstan web tension control.
· Control of scroll speed in continuous-process centrifuges.
TORSPEC Variable Speed Drives used as brakes:
1. The standard Eddy Current Brake will not provide retarding torque at zero
speed so, where full braking effect is required below 200-300 rpm, the TORSPEC
Drive can be run with the motor operating in reverse direction to the process.
This provides braking torque through zero speed.
2. For applications
where alternate drive and braking are required, the TORSPEC Drive can be fitted
with a brake motor.
3. In certain cases it is possible to provide
braking effect by causing the motor to run above its synchronized speed. This
creates a regeneration system so that the braking torque is used to drive the
motor. This system is used for reels, which have to be driven up to speed then
braked. |
