Only use lifting systems and equipment with adequate lifting capacity
for handling. The entire packaging is designed to allow movement with
forklift and forklift truck.
!
4. TRANSPORT AND STORAGE
4.1 Handling
All gearless machines are packed in crates or cages.
Different types of packaging can be used, depending on the size and means
of transport. Unless otherwise specified, the packaging complies with the HPE
guidelines.
In some cases, the machines are mounted on wooden pallets to enable them
to be transported correctly on trucks. The packaging may not be stacked in any
way. It is recommended to check the conditions of the material when it is re-
ceived. In case of damage, do not proceed with the installation unless expressly
authorized by Montanari Giulio & C. Observe the symbols on the packaging to
prevent damage to property or personal injury. Here are the meanings of the
symbols that may appear on the packaging.
Keep dry Handle with care

For lifting, anchor points (eye-
bolts) are provided as shown in
Fig. 4.
Use only the specified eyebolts to
handle the unit.
Fig. 4
! !
4.2 Storage
The gearless machine must be stored in the position of use on a wooden base
not subject to vibrations, in a covered and sheltered place.
If the unit is stored outdoors, it should be covered, taking care that no
moisture and/or other foreign matter can accumulate on it.
!
Supplies for special environmental conditions during transport (e.g.
by ship) and storage (climate, temperature, etc.) must be contractually
agreed.
!
• Check the correct operation of the motor and brake after installation.
• Repairs may only be carried out by the manufacturer or by authorised per-
sonnel.
• The machine can be red-hot.
• These machines must be connected to inverters.
• When the machine is rotating, both manually and mechanically, it can act as
a generator and produce high voltage.
• During configuration, the machine is powered by high voltage.
5. DESCRIPTION
5.1 General description
The MGV20 series gearless machines are permanent magnet motors with
double brake system.

MGV20M - L ENGLISH
5.2 Main components
The unit consists of the main groups as shown in Fig. 5 - 6
MGV20 M - L are equipped with a PTC thermal probe inside the windings to
protect against overheating (winding temperature up to 130°C) and with a ther-
mo-contact for the activation of the fans. Refer to the electrical connections for
more details. - See Par. 6.4.
Lubrication
The gearless machine contains no oil and it is supplied with bearings
already lubricated throughout the life of the machine; no further lubri-
cation is required.

5.3 Brake
The gearless machine is supplied with a brake that conforms to the standards
indicated in paragraph 2.5.
The brake system is pre-calibrated by the manufacturer and no further adjustment
is required.
The brake system operates as follows:
• Not powered (electromagnet not powered): the brake disc is clamped
by the movable surfaces (yellow arrows on Fig. 7). In this condition the system
does not move.
• When the brake electromagnet is powered, it releases the brake disc
(yellow arrows in Fig. 8); now the motor is released.

6. INSTALLATION
6.1 General installation information
The gearless machine must be installed in a building or in a closed travel com-
partment.
Do not use the gearless machine in an explosive atmosphere.
The room temperature must be between 0°C and +40°C.
Assembly and installation must be carried out with great care by qualified and
trained personnel.
The manufacturer cannot be held responsible for damage caused by incorrect
assembly or incorrect installation.
Before starting work, make sure that adequate lifting and handling equipment
is available.
No welding work must be carried out on the unit.
The unit must not be used as a grounding point for welding operations. The
bearings can be irreparably damaged.
All fixing points specified by the manufacturer must be used.
The air supply for cooling must not be prevented.
6.2 Installation surface
The installation surface must be uniform and level.
The levelling tolerance is 0.1 mm.
The installation surface must be rigid and robust enough to withstand the forces
involved.
6.3 Installation procedure
The gearless machine can be lifted using the eyebolts for the insertion of the
belts or lifting chains (see also the paragraph on storage and handling). Particu-
lar attention is needed to avoid that the gearless machine receives blows in cor-
respondence of the brake disc; the brake levers and the electrical connections
of the board are very delicate. Lifting example Fig. 9.
!!
Fig. 9

19
www.montanarigiulio.com
MGV20M - L ENGLISH
Place the unit on the installation surface and secure it.
• Fixing screws and nuts must be tightened to the prescribed torque.
• Use bolts with a minimum strength class of 8.8.
• Do not force or hit the fixings to position them; this could damage the
bearings, rings, etc.
• Mount the safety devices.
N.B.: Tight correctly the eyebolts.
The static load changes depending on the roping direction. (Fig. 10):

• The power cable must be routed separately from the other cables.
• The motor power cable is shielded and the shield must be grounded.
• The encoder cable must be routed away from the motor power cable to avoid
electrical interference.
• The brake system has a power cable and another cable for the microswitch
contacts. (Fig. 12). All electrical data are listed on the label of the brake system.
The microswitch has two contacts: one open and one closed. (Fig. 13).
• These contacts indicate the brake condition (see Tab. 7).
