HFF Asynchronous three-phase brake motor with a.c. brake

Standard and brake motors in a wide and comprehensive series of sizes and designs, suitable to solve every application problem of the drives with asynchronous three-phase brake motor with braking in case of supply failure
Strong and reliable product
Innovating, complete and rigorous documentation





Sizes 63 & 180M

Powers 0,045 & 22 kW
Single-speed 2, 4, 6, 8 poles 230 Y 400 V 50 Hz (sizes 63 & 160S) and 400 V 50 Hz (sizes 100 & 180M)
Two-speed 2.4, 4.6, 4.8, 6.8 poles 400 V 50 Hz (sizes 63 & 180M) and 2.6, 2.8, 2.12 poles 400 V 50 Hz (sizes 63 & 132)
Sizes 63 & 132 available also with higher powers than the ones foreseen by the standards
Class F insulation, temperature rise class B/F for all single-speed motors at standardized power, F for the remaining
Mounting positions IM B3, standard and non-standard IM B5, IM B14 and corresponding vertical mounting positions
IP 54 protection for sizes 63 & 160S and IP 55 for sizes 160 & 180M
Particularly strong construction (both electrical and mechanical) to withstand alternating torsional and thermic stresses of starting and braking; duly proportioned bearings
«Supported» tightening attachments of endshields and flanges fitted on casing with «tight» coupling
Electromagnetic sizing especially studied to allow high acceleration capacity and uniform starting (slightly «sagged» characteristic curves)
Double braking surface, high braking torque (usually ) and adjustable with continuity
Maximum quickness and precision in releasing and braking (typical of a.c. brake) and maximum frequency of braking
High braking capacity
Maximum frequency of starting for the motor (rapidity in brake releasing allows a completely free start also at high frequencies of starting)
Particularly suitable for applications requiring strong and very rapid brakings together with a high number of starts
Asbestos-free friction surfaces
Wide metallic terminal box, IP 55 protection
Suitable for operation with inverter
Designs available for every application need

Motor sizes 63 & 160S can be supplied in certified design to CSA and UL standards
