Field Of Application; General Safety Information; Receipt And Storage - MGM BM SERIE Instrucciones De Empleo Y Mantenimiento

We would like to thank you for trusting us and buying our product. Before starting the motor, we advise you to read these instructions
carefully, which should be kept together with it. Should any difficult arise, please contact the MGM organization, specifying the type of
product and its serial number.

Field of application

These instruction are valid for electric motors belonging to the BM series (BM, BMS, BMPV, BMBM,BML ,BMM, BMAV). For motors
belonging to the BMBM, BMPV, BMMP, BMAV series and for special execution motors follow the specific 'Additional Instructions'
which should be kept together with this Use and Maintenance manual.
Further information are available on our web site (www.mgmrestop.com)
BM series includes asynchronous three-phase or single-phase totally enclosed fan cooled brake motors. The motors brake in case of
power supply failure. BM serie-motors are used as components in industrial applications. Performance and characteristics shown on
the motor nameplate are guaranteed for installations in ambients having a temperature range between -15°C and +40°C at an altitude
below 1000 m. above sea level.

General safety information

During operation, motors have live or moving parts. Therefore, removal of electrical or me-chanical guards,
improper use, or inadequate maintenance may cause serious damage to persons or property.
Installation, Maintenance, Adjustment, Replacement operations of components must be carried out by qualified
personnel, using proper tools and working instruments. Above all, it is essential to verify that motor or plant are
disconnected from the supply line and that on board terminals there is no voltage left.
In case of uneffective braking during regulation, maintenance or replacement operations of components, check that
no load is applied to the driveshaft.
Avoid contact with the motor case since the temperature under normal operating conditions may exceed 50°C

Receipt and Storage

When receiving the motor, it is essential to check that:
- all the characteristics shown on the motor nameplate correspond to the requested ones;
- the motor has not been damaged during transportation; any damage must be pointed out to the carrier immediately.
The ringbolts, if any must be used to lift only the motor without any other machines fitted to it.
The motors must be stored in a sheltered, dry and dust-free place.
Installation
When the installation is started, be sure that the characteristics expected from the motor are in accordance with the ones shown on the
motor nameplate, being careful to the supply voltage and to the maximum braking torque. Make sure that the braking torque supplied by
the brake assembly is suitable for the application required.
Please verify that the type of brake is suitable for the application and in compliance with standards or rules in force on the machine on
which the motor will be incorporated.
BM series doesn't include motors suitable for hazardous environment. Misapplication of a motor in hazardous environment can cause
fire or an explosion and result in serious injury.
Verify the IP protection degree stated on the nameplate is suitable for application required. For outdoor installations, it's recommend to
protect the motor against exposure to the sun and against bad wheather conditions. Pls check the cables entry isn't on the top of the
terminal box. We suggest in any case that the connection cables come from the bottom upwards in order to avoid drip and water
stagnation at cable entry. For outdoor vertical mounting with shaft down a special rain canopy is required.
Check that all gaskets are in perfect conditions and well housed into their seats; check that the cable inlet openings are tightly closed
and the terminal box screws well tightened so that the protection level shown on the plate is respected.
The ringbolts if removed must be replaced with screws with the same length and pitch to guarantee the IP protection degree.
The motor must be installed in a ventilated room away from heat sources and in a such a position to allow free air intake for a proper
ventilation. The motor must be also mounted in a such a position that easy inspection and maintenance is allowed, avoiding possible
danger arising from contact with moving parts
Before starting the motoror after long periods of inactivity or storage, check that the earth inulation resistance is not less than 25 M (the
measuring must be done with a 500W DC Megger instrument).
Never touch the terminals during and immediately after measurement since they may carry dangerous voltages.
The motor is balanced with half key fitted (60034-14).
When mounting the motor, check that the fixing screws have suitable material and proper diameter to be fitted with the holes provided on
flange or feet. If the motor equipped with feet, a rigid and solid surface is to be used, in order to have minimum vibrations during
operation. During the mounting operation, check that motor and machine coupling is accurately aligned, as an imperfect alignment
could cause vibrations. In case of motors with flange, make sure that coupling surfaces are thoroughly cleaned and that the centering is
properly done so to allow screws going through easily. In case of motors with feet , when using couplings with joints, check that the motor
axis and the driven machine axis are in line. When using pulleys, check that the belt tension is not too high.
