Compact brake motors ATK TYPE – DIRECT CURRENT BRAKE
Product characteristics
6ATK – 6ATKH – 7ATK – 7ATKH SERIES
The range includes axis heights from MEC 63 to MEC 280.
Up to an axis height of 132, the motors have an aluminium casing with long-life lubrication of the 2RS type, and modular fixing feet; the sizes from 160 to 280, instead, have a cast iron casing and SKF bearings, an external greaser for periodic lubrication and PTC sensors on the windings.
The ATK type brake is powered by direct current and has a very high braking torque; the extremely strong braking group is housed inside an extended fan cover. The ring nut in axis with the drive shaft can be used to adjust the braking torque; the cooling fan of thermoplastic material is keyed to the rear end of the drive shaft.
Because of its performance and construction characteristics, it is perfect for use in heavy duty applications. A rectifier positioned inside the terminal box transforms the incoming alternate current into direct current to supply the brake electromagnet.
