The housing of the brake becomes magnetically energised if dynamic braking processes occur in an application. This can lead to restrictions within the machine or system and increased costs.
The more often a brake switches, the more self-remanence can develop. As a result, the rotor on the brake is no longer powerful enough to rotate freely. The brake locks and the motor stops. Other consequences are increased wear and motor burnout, which can result in the entire machine or system coming to a standstill.
According to KEB, the brake provides a solution for holding loads for flange- and shaft-mounted installation in machines and systems.
The housing of the Combinorm B brake is divided into an inner and outer housing.
Simon Janke, sales brakes and clutches at KEB, said the company developed Combinorm B as an anti-remanence brake. “For this, we rely on an artificially created air gap that prevents the armature part from sticking to the magnet. There are no effects on the torque."
"In addition to mail processing, the classic areas in which the brake is used include winding devices, door and gate systems, roller conveyors, balancing or sorting machines," Janke adds.
The solution is also suitable for medical technology and packaging machines.
The brake is also expected to offer short switching times, which is said to increase safety in the machine.
