Hoisting Motors

BAPK 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). BAPK 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 (locked rotor) torque by 20% aboutand that reduces the starting (locked rotor) current 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 guaranteebest reliability of brake motors for hoist manufacturer application. Shields and flanges are made of cast iron. Frame is made of aluminium from100 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 have to be clearly stated in the order (i.e. BAPK 112 MB4/16).

K Brake Disc

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 asstandard on motors starting from 160 up to 225 frame size while it’s available on request on motors from 100 up to 132 frame size.BA 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 or under high environment temperature (50 ° C or above).K brake disc have a shorter lasting than standard brake disc as a consequence of the increased moment of inertia therefore it’s advisable touse 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 have to the clearly stated in the order (i.e. BAK 112 MB4).

Premium Brake Torque motors – BAF series

BAF series motors are brake discs motors providing a very high brake torque. BAF series motors are particularly suitable for thoseapplications where it’s needed to keep the motor locked up also under a very high turning moment. BAF series motors are providedwith AC brake. BAF motors are available starting from 100 up to 225 frame size. The table below shows the BAF series brake torquevalues.
