ELECTROMAGNETIC SPRING REACTION BRAKE Type FZ-.../1 1 friction disc Torque regulation dimension e: min. torque dimension f: max. torque (with/reg.) With hand-operated unblocking system Type FZ Description The electromagnetic safety brake type FZ makes up a unit suitable for working with horizontal shafts, with a high reliability degree, a good heat dissipation, a quick response speed and a minimum residual torque. Ask us when required for working with vertical shafts. This unit is provided with a “manual emergency unblocking system”, for those cases in which it is necessary to disactivate it without the aid of the electromagnet. (without/ reg.) 1. Inducing core 2.

Unblocking pins 13. Regulating nuts for unblocking operation 14. Intermediate springs Type FZ-.../2 2 friction discs Versions We manufacture only one version, for working under dry conditions. Optionally and on request, it can be delivered: 1. With torque adjustment, which enables you to control the braking action. 2. With hand-operated unblocking by means of lever. For those cases in which this has to be effected frequently. 3. With protection cover. For those cases in which work has to be carried out under aggressive conditions, dust, water, etc. See Fig. A for physical dimensions. The standard voltage is 24 V.D.C. Other voltages on request. 9. Friction disc (additional one) When exciting the coil housed inside core 1 with current, it generates a magnetic field which draws the armature 7, overcoming the resistance of the springs 2, whereby the friction disc 9 and the pinion 10 are triggered, causing thus the unit to be brake released. When chopping the electric current and dropping out the magnetic force, the springs 2 impel the armature 7 against the friction disc 9, whereby the letter is trapped against part 8 which is anchored to the machine bedframe by means of the screws 11. As the friction disc is connected to the pinion 10 which is, in its turn, splined on to the shaft, this will be braked. Hand unblocking operation: It will enough to tight butt the 2 nuts 13 (Fig. 3), to put the brake into operation again, unscrew them approximately 2 turns. Torque regulation: In the units provided with torque regulation part 4 will be screwn down or unscrewn, until obtaining the required braking action (Fig. 4).
