The Demag KBA 71 A 4 is a conical rotor brake motor designed for applications requiring reliable and efficient braking action. It has an output of 0.60 HP and a brake torque of 6.7 lb-ft, making it suitable for demanding start-stop operations with high cycle rates. The motor features a unique design where the brake is mechanically linked to the rotor, allowing for synchronized motor start-up and brake release, as well as motor shut-off and brake application. This integration eliminates the need for separate control systems or additional switching elements. The KBA 71 A 4 is characterized by effective heat dissipation through its large-format brake cap, which contributes to longer service life for the brake linings. The brake disc also functions as a fan, reducing the overall housing length while maintaining good thermal management. This motor is particularly advantageous in environments where high braking energy and durability are essential, as it can handle a high number of starts and stops per hour without being affected by temporary overloads.
The Demag KB conical-rotor brake motor provides you with a brake motor that utilizes a unique operating principle: The brake is not separately controlled, but firmly connected to the rotor, i.e. integrated. This means that motor start-up and brake release as well as motor switch-off and brake application are each synchronized.
Applications
The Demag KB conical-rotor brake motor features a remarkably simple, robust and reliable brake system. It is an outstanding solution wherever demanding requirements have to be met by the brake.
