1. AC brake
Fail-safe electromagnetic brake: it brakes when power is off. When the supply is cut, the pressure springs push the moving armature against the disc and the motor flange, locking rotation. Connected in the motor terminal box at 230/400 V ±5% 50 Hz.
2. DC brake
Power-on brake: it brakes when energised. Powering the coil, the moving armature overcomes the annular spring and engages the friction lining, stopping the motor shaft via the key. Standard voltage 24 V DC (±10%), class B insulation.
3. DC brake, “S” series (compact)
Ideal for machines with limited space: a very compact fail-safe system. With no current, the springs press the armature’s friction lining against a cast-iron fan fixed to the shaft. Standard voltage 230 V 50–60 Hz.
