IMPORTANT WARNING
These symbols
appear in this document whenever it is important to take special precautions
during installation, operation, maintenance or servicing of the motors.
It is essential that electric motors are installed by experienced, qualied and authorized personnel.
In accordance with the main requirements of EEC Directives, the safety of people, animals and property
should be ensured when tting the motors into machines.
Particular attention must be given to equipotential ground or earthing connections.
The following preliminary precautions must be taken before working on any stationary
device:
• Mains voltage disconnected and no residual voltage present
• Careful examination of the causes of the stoppage
(jammed transmission - loss of phase - cut-out due to thermal protection, etc)
Even when not supplied with power, there is voltage at the terminals of a rotating
synchronous motor with magnets.
Accordingly, before carrying out any work check carefully that the motor is not
rotating.
The short-circuiting of the phases is not allowed to manage the rescue operation of
the lift.
For dismantling the E27 motor only
Assembly or maintenance of the rotor must not be carried out by people with pacemakers or
any other implanted medical electronic device.
The motor rotor contains a powerful magnetic eld. When the rotor is separated from the
motor, its eld may affect pacemakers or disturb digital devices such as watches, mobile
phones, etc.

any work on the motor or the brakes.
1.2 - Application
E27 motor is designed as a gearless drive for elevators.
No other drive application is permitted without a written
agreement from Nidec / Leroy-Somer.
E27 motor is a permanent magnet synchronous motor. Due
to its very compact design, E27 is ideal for applications in
machine roomless elevators
2 - RECEIPT & IDENTIFICATION
Inspect the machine as soon as it is received. If there is any
damage that has been caused during transportation, contact
immediately the carrier.
As soon as you receive the machine, check that the nameplate
on the machine conforms to your order, see details below.

The rated characteristics are given for operation in a standard
environment (see IEC 600034-5):
- altitude less than 1000 m
- maximum relative humidity < 60%
- temperature between 0 and 40°C
Derating data can be provided if special conditions are
indicated at the time when the equipment is ordered.
4 - STORAGE
4.1 - Storage conditions
The gearless should be stored in a horizontal position.
The location must be dry and protected from harsh weather
conditions, cold (temperature above -15°C), frequent
temperature variations (to prevent the risk of condensation)
and free from vibration, dust and corrosive gases.
If there is any vibration in the storage area, it is advisable to
rotate the driving sheave at least twice a month (supply power
to the brakes in order to be able to turn the sheave).
For certain transport conditions the grooves of the driving
sheave are protected by a special varnish. This varnish must
not be removed during storage.

5323 en - 2018.04 / c
INSTALLATION
4.2 - Prolonged storage (> 3 months)
- Place the machine in a sealed waterproof enclosure with
a dehydrating bag inside corresponding to the volume to be
protected and the degree of humidity of the location.
- The bearings which can not be regreased must be replaced
after a storage longer than 3 years.
5 - INSTALLATION
5.1 - Before installation
If the equipment has been stored for several months, it is
essential to check the correct insulation between the phases
and the earth terminal on the motor (minimum 100 MΩ at
500 V D.C. for 60 seconds) after having disconnected all the
electronic circuits if necessary.
Do not apply the megohmmeter to the terminals of the
thermal sensors as this may damage them.
If the required value is not reached, dry the motor using
internal or external heating.
Drying using external heating
- Place the motor in an oven at 70°C for at least 24 hours until
the correct insulation is obtained (100 MΩ).
- Take care to increase the temperature gradually to clear the
condensation.
- After drying at ambient temperature during the cooling
phase, check the insulation value regularly, as it will initially
tend to fall, then rise.
5.2 - General recommendation
The installation must comply with the motor characteristics
indicated on the nameplate (see section 1).
It must include electrical safety devices.
Check that the handling equipment (slings, etc.) is suitable
for the weight of the machine.
Use the attachment points provided on the machine.
Check that the cables are correctly positioned so that they
are not damaged.
Provide the necessary mechanical protection devices to
prevent people working on the machine becoming caught or
trapped by the sheave and/or the cables.
During building works, we recommend to protect the brakes
and micro-switches against dust (by wrapping them into a
shrink lm for example). If the site is permanently subject to
dust, we recommend to t the brakes cover available as an
option.
The motors must be installed in such a way that the cooling
air (not too damp, dust-free, and containing no corrosive
gases or vapors) circulates freely.
For the ease of access to the encoder, we recommend to
install the motor with a minimum distance of 200mm between
the cast iron cover protecting the encoder and the wall of the
elevator shaft.
5.3 - Mechanical installation
5.3.1 - Lifting the motor
Drying using internal heating (drawing 1)
- Connect motor windings V1 and W1 in parallel in relation
to U1.
- Read off the resistance between U and V//W.
- Apply a low voltage D.C. current to them (to obtain 10% of
the rated current calculated using the winding resistances),
then increase the voltage until 50% of the rated current is
reached
- Maintain the power for 4 hours. The temperature of the
motor should increase slightly.
If the brakes are released, the sheave will move
slightly on power-up (angular setting of the rotor in
relation to the stator).

2. PRODUCT DISCRIPTION:
2.1. Operating principle:
The EVO brake family belongs to the compression spring type of brakes. In the absence of an electric
current, springs, located in their casing, exercise a force on the mobile plates that stops the movement
of the friction disc. When the electromagnet is connected, the magnetic field generated attracts the
mobile plates, displacing them and releasing the friction disc. The displacement of the mobile plates
may be monitored by use of detectors (micro-switches).

2.6. Product reception:
The type of packaging may vary according to the brake model and the shipping batch.
2.7. Warranty:
Unless there is a specific agreement with the client, the terms of Warranty shall be the general
ALZOLA terms, set in the quotation conditions.
Any modification or manipulation carried out on the brake without the express authorization of
ALZOLA, as with any use not complying with the technical specifications set by ALZOLA, shall lead
to the suppression of the Warranty and the annulment of ALZOLA’s liability with regard to the nonconformity.
2.8. Legal regulations:
UNE-EN 81-20/50: 2014: Safety rules for the construction and installation of lifts. Part 1: electric
lifts.
In order for the brake to conform to the directive 2014/33/UE, the integrator must respect the
general implementation and use conditions defined in the CE type certificate exam established by
the notified body.

3 MECHANICAL INSTALLATION:
3.1 Before starting:
Check that the brake is suitable for the machine. Check the characteristics plate check that both the
operating voltage and the braking torque correspond to the requirements for the installation.
3.2 Tools:
Degreasing agent
Scissors
Allen Keys
Screwdriver
Feeler gauge
Torque wrench
3.3 Installation:
1º- Check the position is perpendicular between the axle and the support surface of the brake.
Danger: Do not hang the brake from the cables: this may lead to damage to the
brake and/or the brake falling.
2º- Degrease the friction material support surfaces.
Danger: Deficient cleaning of the braking surfaces may lead to a decrease in the
brake torque.
We recommend the use of Loctite® 7063 or similar. Procedure: Apply the spray on the two support
sides of the brake disc. Clean both sides with a clean cloth. Repeat the process until no dirt shows
on the cloth.
3º- Place the disc in the machine axle groove. Remove the film protection from the disc. Move the
disc to its end position in contact with the braking surface of the machine. The adjustment must slide
and not be loose.
Danger if loose.
The disc brakes must not be contaminated.

Fig. 5
4º- Position the brake in the machine and clamp it to it by tightening the corresponding fixing screws.
You should guarantee the correct concentricity between the machine axle and the central gap of the
brake (in which the encoder is usually clamped).
3.4 Screw tightening torques:
Screw tightening torques must be respected: insufficient tightening may lead to the separation hubs
being displaced and the corresponding transmission of the braking torque to the fixing screws, with
the risk of them shearing. An excessive tightening may also jeopardise the safety of the brake. The
use of torque wrenches is recommended.

These screws are painted red. Clamp the mobile plates to the casing through the holes found in the
casing. They must be removed following the mechanical installation of the brake. Tightening them
will cause the mechanical release of the brake. They must never be placed in the installation, to avoid
them being accidentally tightened and causing the lift to fall.

3.6 Positioning the rubber dust cover:
Position the rubber dust cover before plugging in
connection.

Once the brake has been clamped to the machine place the rubber. The rubber avoids the insertion
of dirt particles in the mobile parts the brake. Precaution: It is not prepared to prevent penetration
by liquids.
Optical detectors must be covered, as they are sensitive to dirt and light.

Installation Process:
EVO brakes may be factory supplied with the lever, but if this is not the case, and installation was
required by the client, the following procedure should be observed:
Following a mechanical and electric installation of the brake
1- Remove the central caps from the brake:
