 ComDrive Eddy Current Brake Units are constructed from high quality tested and Mill certified materials. Cooling is provided by a separately driven forced air cooling fan motor with in-built air flow sensor which is coupled into and monitored by the Prospeed Closed Loop Control System. The fan assembly can be oriented during manufacture if required to suit close headroom installations. One level of Thermistor protection is provided as standard to protect against temperature rise. A Metrosil device is also incorporated to protect against field spikes. |
|
 ComDrive Eddy Current Brake Units are IP54 rated and are available in 4 sizes from 2.2kW to 150kW. The ComDrive machine is simple and reliable and is similar in construction to squirrel cage motor (induction), but has a D.C. field coil system with a solid steel balanced rotor. There is no need for carbon brush gear and very little maintenance is required other than occasional (6 monthly) greasing of rotor shaft bearings via the fitted lubrication system and replacement of the ventilation filters. |
