Ziehl-Abegg presents new products at Interlift.

Ziehl-Abegg is showcasing SM132 and SM210 elevator motors designed to minimize space, cost and weight, along with the ZAdisc disc rotor motor and ZAsbm4C electronic brake control, at Interlift.

Compared with motors of equal power, the frameless SM132 elevator motor (with a traction sheave from 120 to 160 mm) has been reduced in size from 245 mm to 205 mm. The approximately 15% smaller machine has a new design in which the stator is fixed between the bearing brackets. This also reduces weight by nearly a third, from 150 to 108 kg.

SM132 allows for the design of elevator systems with payloads between 480 and 1050 kg. “If no traction sheaves are used, elevator planners can make full use of the possibilities of the new suspension elements in their designs,” states Werner Bundscherer, head of the Drive division. “We offer our customers the ability to make consistent use of the new plastic-coated elevator ropes.”

The ZAtop SM210 also saves space, weight and cost. It can transport loads from 675 to 2000 kg using traction sheaves from 320 to 520 mm.

ZAdisc, a new disc rotor motor, is extremely flat and can be mounted directly onto the car’s guiding rail. Intended for use in limited space, the drive can handle a payload of 480-1050 kg using 400 and 480 traction sheaves.

The ZAsbm4C electronic brake control eliminates noise and electromagnetic disturbances. It is EN 81-20-compliant and can be easily fitted for retrofitting existing frequency inverters.
