Description
About BFK470 spring-applied brake
- 7 sizes
- Standard voltages [V DC] 24, 103, 180, 205
- Graduated torque range from 2 - 370 Nm
- Enclosure complies with up to IP66
Torque transmission
- Friction locking in dry running
Fast and easy mounting
- Air gap preset
- Rated torques are achieved after only a few switching cycles, thanks to special machining of the friction surfaces
- Fixed bearing is not required on the brake
Mechanical design
- Insulation system complies with temperature class F (155 °C) and ensures that the winding has a long service life
- The brakes are designed for 100 % duty cycle
- Long, low-wear rotor-hub connection with tried and tested involute gear
- Low-wear, asbestos-free, solvent-free friction linings
Options
- Hand-release complying with IP66 enclosure for manual release over all sizes, release is possible in both directions
- Noise-reduced rotor ❙ Function monitoring through inductive proximity sensor complying with IP66, ambient temperature range: -25°C to +120°C (available from size 12)
- Non-standard voltages and bores on request
- Pulse width modulation (PWM)
- Partial discharge free brake has been developed for operation with the pulse width modulated DC bus voltage of a frequency inverter.
- Rated coil voltage UN=103V DC
Temperature-resistant up to minus 40˚C
- CCV (Cold Climate Version) optional
- Option for inductive proximity sensor: Information evaluation only for range -25°C to +120°C
Corrosion protection up to class C5
- Ready for coating, in accordance with norm EN ISO 12944
- Corrosion protection class C4 or C5, depending on the coating system used
