Eddy-Current Drives - TASC & HEENAN
The full TASC and HEENAN ranges of air cooled eddy-current drives, with infinitely variable speed or torque control up to 110kW.
The TASC TR, CD, 1D and HEENAN VH, 912/914 types feature high starting torque, wide speed range at constant torque, no routine maintenance, accurate closed loop speed control, torque or tension control and compact electronic control systems.
Ranges of TASC units are also available for centrifugal fans and pumps and Eddy Current braking applications.
’CD’ Eddy-Current Drive
’’TR’ Eddy-Current Drive and Controller |
HEENAN liquid cooled Eddy Current drives and couplings are heavy duty, four bearing machines with high starting and running torque’s. With all the benefits of their air cooled cousins, the use of a liquid coolant system enables a greater power output of up to 5000kW.
Eddy-Current drives are used in all industries, typically
- Agricultural machinery
- Textile management
- Packaging
- Conveyors and materials handling
- Poultry processing
- Water distribution
- Air conditioning
- Building services
- Tobacco machinery
- Petrochemical

‘VH’ Variable Speed Eddy-Current Drive |
Heenan Eddy-Current drives have a wide speed range at full load rated torque with a high overload capacity (up to the pull-out torque of the AC motor) available for starting or to deal with transient overloads.
Accurate control of speed/torque is available using feedback signals from either the built in AC tacho generator, an externally driven DC tacho generator of shaft encoder.
Fully engineered control schemes are available for any drive application and because of the low control power involved, these are virtually free from the generation of harmonic interference.
