HFV Asynchronous three-phase brake motor with d.c. brake

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 .. .160S
Powers 0,045 & 15 kW
Single-speed 2, 4, 6, 8 poles 230 Y 400 V 50 Hz (sizes 63 & 160S) and 400 V 50 Hz (sizes 100 & 160S)
Two-speed 2.4, 4.6, 4.8, 6.8 poles 400 V 50 Hz (sizes 63 & 160S) and 2.6, 2.8, 2.12 poles 400 V 50 Hz (sizes 100 & 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 remaining motors
Mounting positions IM B3, IM B5 standard and non-standard, IM B14 and corresponding vertical mounting positions
IP 54 protection for sizes 63 & 160S and IP 55 on request
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)
Very reduced motor overall dimensions which are nearly the same of a non-braking motor; maximum economy
Single braking surface, fixed braking torque (usually )
High braking capacity for each braking thanks to cast iron fan (which also acts as brake disk) especially sized in order to achieve the dissipation of high braking energies
Also available for single-phase supply
Particularly suitable for cutting machines, safety stops, as parking brake, etc.
Asbestos-free friction surfaces
Wide metallic terminal box, IP 55 protection
Suitable for operations with inverter
Designs available for every application need

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