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.

upon their arrival on site. If any damage incurred in transit
is found, make a notice of claim in the presenceof the carrier.
If necessary, do not put these machines into operation.
Transport
Observe the relevant safety regulations and
take the centre of gravity into account when
handling the lift machines.
The two eyebolts are designed for the specified machine
weight. it is not permitted to suspend additional loads.
Storage
Store the motors only in closed, dry, dust-free, well-ven-
tilated and vibration-free rooms (storage temperature: -20°C
to 60°C ). Do not store lift machines in the open air.
Parts are
not suf ciently preserved to withstand extended periods of
exposure.
Avoid excessive storage periods (recommendation: max. one
year).
After prolonged storage (>3 months), rotate the motor in
both directions at a low speed (< 20 min-1) to allow the
grease to distribute evenly in the bearings.
Warning
Options:
rMechanical evacuation
rBrake remote release system (for MRL solution)
rEncoder cables
Measure the insulation resistance before initial operation
of the machine. If the value has dropped below < 1 k
per volt of rated voltage, the winding needs to be dried
(insulation meter voltage: 1,000 V DC).
This can be done, for instance, with heated air, in a drying
oven, or by applying a d.c. voltage to the motor connections.
Make sure that the voltage selected does not exceed the values
shown in the gure "Drying the winding". Let the temperature
rise to about 70 – 80°C and maintain it for several hours.
Drying the winding
Unpacking
Dispose of the packaging material in an
environmentally friendly manner or reuse it.

9. Installation
Be sure to check the base frame or founda-
tion loads by calculation before installing the
lift machine.
The lift machine may only be installed if the relevant safety
precautions have been met. The machines can be used in lift
systems with or without a machine room but only installed
in vertical load case.
The machines may only be installed, electrically connect-
ed and put into operation by trained specialist personnel.
The system-speci c conditions and the requirements of the
system manufacturer or plant constructor must be met.
Cover the machine and especially the brakes
when doing any machining or dust- producing
work in the shaft or machine room.
The measuring system is only accessible from
the rear side. Therefore, leave enough space
(min.800mm) between the wall and the
rear side of the machine or ensure that the
machine can be moved away from the wall.
Degree of protection
WSG09.X Lift machines are designed with degree of
protection IP 40. Make sure that the cable entries to
the terminal boxes are sealed properly when making the
electrical installation.
Ambient conditions
The following ambient conditions must be ensured on site:
Altitude: max. 1,000 m a.s.l.
Ambient temperature: + 5 ... 40°C
Max. rel. humidity: 85 % at 20°C
(no moisture condensation)
Install the machine so that ventilation is not obstructed,
i.e. suf cient heat dissipation by convection and radia- tion
must be ensured.
Warning
Note
Danger
The torque and power values indicated in the Technical. Data
apply to the above ambient temperatures and altitudes. In
case of a deviating altitude and/or ambient temperature, the
reduction factors k shown in the diagram below must be us
-ed.

Fastening the machine
The machine or base frame should be mounted
on rubber pads for vibration damping.
The machine is fastened using 4x M24 bolts
(strength class8.8;).
The permissible unevenness of the mounting surface is
0.1 mm. The mounting surface must be sufficiently dis-
tortion-resistant and stable to accommodate the forces
occurring in the system.
After completing the adjusting work, tighten
the 4 fastening bolts of the machine, using the
speci ed torque.
No welding work may be performed on the lift
machine, This could destroy the bearings and
the magnets.
Lift machines are generally equipped with rope slip-off
guards. After putting the ropes in place, adjust them so that
the distance between the rope and the rope slip-off guard
does not exceed 1 mm.

10.1. General
The electrical connection may only be made by
a quali ed electrician.
Before starting any work on the machines,
ensure that the lift machine or system is
properly isolated.
Before making any connections check that
rthe connecting cables are suitable for their specific
application and for the relevant voltages and currents.
rthe suf ciently dimensioned connecting cables and torsion, strain
and shear relief as well as anti-kink protection are provided.
rProper earthing
rthere are no foreign bodies, dirt or moisture in the terminal
boxes
rcable entries not in use and the terminal box itself are
tightly sealed to prevent the ingress of dust or water.
The insulation system of the motors is designed
such that they can be connected to a converter
with a maximum d.c. link
Danger
Note
Terminal box for motor connection
The motor cable must be shielded.
The motor phases U1, V1 and W1 must be
connected correctly to the corresponding
voltage Ulink max up to max. 620 Volt.
Note: Ulink max is the maximum value of the
d.c. link voltage which is only transient and
approximately equivalent to the inception
voltage of the braking chopper or of the energy
recovery unit.

Cable cross-section required
The currents speci ed under the machine data
for the series WSG09.X refer to duty type S3-
40%. This must be taken into account when
selecting the cable cross section required.
The continuous Ir.m.s. value required for the
selected cable is approxi- mated from:
I r.m.s. (cable) = I N (motor, S3-40%) / 1.58
The following table gives the recommended values for the
current carrying capacity of PVC cables at a maxi- mum
ambient temperature of 40 °C:

PTC-thermistor
The operating voltage of the PTC thermistors is
not allowed to exceed 25 V DC.
Earthing
For safety reasons, it is very important that the motor be
properly and carefully earthed.
It is essential to use the earthing terminal
in the terminal box. In addition, an earth-
ing screw is provided on the motor frame for
the connection of a protective or earthing
conductor as specified in VDE 0100 and VDE
0141 respectively.
Short-circuiting
The motor terminals of the synchronous lift
machines,type WSG09.X,can be short circuit-
ed, if required, to brake the lift machine faster.
This is, however, only permissible at speeds less
than the rated speed of the respective motor.

(emergency stop) or during an inspection from the d.c. side,
since this ensures a faster braking effect with the car being
stopped earlier.
It is therefore recommended to use 2 separate contactors for
the brake control circuitry , one of which switching at the d.c.
side, the other one at the a.c. side.
D.c. side switching
rNoisy switching.
rBurn-up protection for switching contact required.
(e.g. varistor, free-wheeling diode)
rFast application of the brake.
A.c. side switching
rLow-noise switching of the brake.
rNo protective measures required for switching contact.
rSlow application of the brake.

10.4. Brake
The brakes are supplied and held with
110V DC . 75-80V DC
.
The recti er has to be prepared by customer.
Following is two recommend solution for the
brake switching which must be realized by the
control circuit from customer controller.
Note on the use of d.c./a.c. side switching:
A.c. side switching is recommended for nor-
mal operation, since the lift machine is then
decelerated in a controlled manner to zero speed
and the switching noise of the brake is negligible.
Note
Note
for holding voltage is preferred for best performances in tem
-perature rise.The connecting contacts for the micro-switches
which monitor the brakes are also accommodated in this term
-inal box.
Monitoring the brakes
The switching state of the brakes is monitored
using dust-proof micro switches with gold
contacts. Both NC and NO contact is prepared
in terminal box. Please refer the connection
advice in the box for connecting according to
request of the control system as following,
