HEENAN Eddy Current Drives and Controls
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.
HEENAN VH and 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.
HEENAN water-cooled Eddy Current drives and couplings are heavy-duty, four bearing machines with high starting and running torques. 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.
