We are manufacturer of Electromagnetic Brakes.We manufacture DC Spring Loaded fail safe brakes type EFSB from torque 4 NM to 500 Nm in voltages of 24 VDC , 96 VDc and 190 VDC with manual release handle also We also manufacture normally off flange mounted brakes type EFMB We also manufacture AC Fail Safe Brakes complete range
Electromagnetic Spring Loaded Fail Safe Brake EFSB
High Operating Frequency with manual release provision.
Coil with class 'F' insulation
All metal parts are Rust Protected.
Two Friction Surfaces
Low Power Requirement
Working of EFSB:The braking torque in EXCEL spring loaded fail-safe brake is generated by several compression springs whose axial spring force presses the armature plate against the rotor which in turn is pushed against the mounting flange. On applying direct current power supply to the coil magnetic field is produced, which pulls the armature plate over the airgap towards the "STATOR" against the spring force and the rotor is free to rotate and hence brake is released.
Working of EFMB:When dc voltage is supplied to the coil the armature is attracted towards the brake liner of the stator and the friction stops the rotating component. When supply is cut off the "prestressed" spring pulls back the armature plate and hence the brake is free. Electrical Connections:The Brakes are operated with DC. connection from three phase or AC mains network can be made via a transformer rectifier, bridge rectifier or half wave rectifier. To restrict the high inductive voltage / back EMF a suitable Supressor and Capacitor.
