英航F series motors are brake discs motors providing a very high brake torque. BAF series motors are particularly suitable for those
applications where it’s needed to keep the motor locked up also under a very high turning moment. BAF series motors are provided
with AC brake. BAF motors are available starting from 100 up to 225 frame size. The table below shows the BAF series brake torque
values.
Premium Brake Torque Motors – BAF series
英航F series
英航PK series motors are available starting from 100 up to 225 frame size. Powers and poles are the same as the BA series motors
(see BA technical data).
英航PK series motors have the same motor construction as BA series motors but present some special parts. Single and most-off
the two speed BAPK motors are fitted with a special rotor (P rotor) that increases the starting torque (locked rotor) by 20% about
and that reduces the starting current (locked rotor) by 10% about.
The brake disc nucleus and hub are made of steel (see k brake disc section). AC brake coil is provided to secure a fast brake
intervention. Feet are frame integrated on B3 mounting (foot mounted) and not simply attached to the frame. This feature guarantee
best reliability of brake motors for hoist application. Shields and flanges are made of cast iron. Frame is made of aluminium from
100 up to 132 frame size (132 cast iron frame is available on request) while it is made of cast iron starting from 160 frame size.
Dimensions are the same as the BA series (dimensions sheet pag. 34). To purchase BAPK series motors the writing BAPK has to
be clearly stated in the order (i.e. BAPK 112 MB4/16).
Hoisting Motors
英航PK series
Nucleus and hub of K brake disc are made of steel that means a higher sturdiness and moment of inertia. The K brake disc is provided as
standard on motors starting from 160 frame size while it’s available on request on motors from 100 up to 132 frame size.
英航standard brake motors up to 132 frame size are made of a special aluminium/thermoplastic material.
K brake disc is strongly recommended for hoisting application, safety application or under high environment temperature (50
°
C or above).
For further information please contact MGM.
K brake disc has a shorter lasting than standard brake disc as a consequence of the increased moment of inertia therefore it’s advisable to
use standard brake disc on heavy start/stop duty cycle application where the k disc is not necessary. To purchase motors with K brake disc,
the writing BAK has to be clearly stated in the order (i.e. BAK 112 MB4).
