Manual for Electric Motors
FOREWORD
The electric motor is an equipment widely used by man in the industrial development as most of
the machines he has been inventing depend on it. Taking into consideration the prominent role
the electric motor plays on people’s life, it must be regarded as a prime power unit embodying
features that require special care including its installation and maintenance in order to ensure
perfect operation and longer life to the unit. This means that the electric motor should receive
particular attention. The INSTALLATION AND MAINTENANCE MANUAL FOR LOW VOLTAGE
THREE-PHASE INDUCTION MOTORS intends to assist those who deal with electric machines
facilitating their task to preserve the most important item of the unit: THE ELECTRIC MOTOR.
