Gearless Synchronous Lift Machines
WSG-10
Operating and Maintenance Manual
2. PRODUCT DESCRIPTION
The gearless WSG-10 lift machines are designed by
outer rotor for gearless traction lifts with or without
a machine room. They are intended for operation
with a 2:1 suspension and are distinguished by their
high efciency, extremely low noise and excellent
operating characteristics.
The WSG-10 gearless synchronous lift machines are
designed solely for use with electronic frequency
inverters. The synchronous motor has been
designed for various rated torques. It can also be
supplied for several rated speeds, which can then
be further adapted to meet individual customer
requirements.
It is composed by housing (1), motor, traction sheave
(2) and block brake(3). The rope slip off guard is
designed to avoid the rope jumping out of the
traction sheave.
The rotor shaft is inserted into the stator frame and
supported in a self-aligning roller bearing (4) at the
traction sheave side. Above it, there is a connection
seats (5) which designed for mechanical evacuation.
The wheels is intent to adapt to the system for the
evacuation in emergency situation as option. At the
other side, the rotor shaft is fixed by a supporting
ball bearing (6) to the housing. the both bearings
were adapted by a heating way during the assembly.
The self-aligning roller bearing is sealed and has a
provision for re-lubrication.
The encoder system (7) is located within the
centre of the machine behind the ball bearing. The
brakes are powered on by1 10V DC . The electrical
connection of the motor is made in the terminal
box (8) where the temperature monitoring device
and brake contactor is also connected. The brakes
are designed such that in the case of failure of one
brake the remaining brakes are able to decelerate a
car carrying a full payload. They are also able to be
released manually.
We would like to refer to the relevant patents held by
KONE Corporation for lifts without machine room.
