The WSG09.X 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.

2. Product description
The gearless WSG09.X 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 ef ciency, extremely low
noise and excellent operating characteristics.
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
by
110V 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.
