Rectifiers :Type EE-022 : 220 VAC / 190 VDCType EE-044 : 440 VAC / 190 VDC
Working :In absence of power the
braking torque 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.
When power to the brake and motor is supplied at the same time brake coi l produces strong magnetic field and pulls the A.P. against the compression springs force towards the stator (Brake Coil) over the air gap and rotor becomes free to rotate.
The attraction of the A.P. and returning to its original position takes place instantaneously and thus fail safe nature is ensured in case of power failure.
Motor can also be supplied with brake Type EFMB and combination Type ECBC.
