1. FOREWORD
The installation, operation and maintenance of the motor must be always performed by qualified personnel
using proper tools and methods and following the instructions contained in the documents supplied with the
motor.
The instructions presented in this document are valid for WEG motors with the following characteristics:
J
Three-phase and single-phase induction motors (squirrel cage rotor);
J
Three-phase permanent magnet motors;
J
Three-phase hybrid motors (squirrel cage rotor + permanent magnets);
The objective of this manual is to provide important information, which must be considered during the shipment,
storage, installation, operation and maintenance of WEG motors. Therefore, we advise to make a careful and detailed
study of the instructions contained herein before performing any procedures on the motor. The noncompliance
with the instructions informed in this manual and others mentioned on the website www.weg.net voids the product
warranty and may cause serious personal injuries and material damages.
Electric motors have energized circuits and exposed rotating parts which may cause injuries to people.
2. SHIPMENT, STORAGE AND HANDLING
Check the conditions of the motor immediately upon receipt. When any damage is noticed, this must be reported in
writing to the transportation company, and immediately communicated to the insurance company and to WEG. In
this case, no installation job can be started before the detected problem has been solved.
Check if the nameplate data matches the invoice data and the environmental conditions in which the motor will be
installed. If the motor is not immediately installed, it must be stored in a clean and dry room protected against dust,
vibrations, gases and corrosive agents, and with relative humidity not exceeding 60%.
In order to prevent water condensation within the motor during the storage period, it is recommended to keep the
space heater ON (where provided). In order to prevent oxidation of the bearings and ensure an even distribution of
the lubricant, rotate the motor shaft at least once a month (at least five turns), always leaving it in a different position.
For bearings with oil mist lubrication systems, the motor must be stored horizontally, independently from the
mounting configuration, with ISO VG 68 oil in the bearing, (the amount is indicated in the motor manual available on
the website www.weg.net) and the shaft must be turned weekly. If the motors are stored for more than two years,
it is recommended to change the bearings, or to remove, wash, inspect and relubricate them before the motor is
started. After this storage period, it is also recommended to change the start capacitors of single-phase motors
since they loss their operating characteristics.
Handle the motor always carefully in order to prevent impacts and damages to the bearings and
always install the shaft transportation/locking device (if supplied) when transporting the motor.
Use only the eyebolts to lift the motor. However these eyebolts are designed for the motor
weight only. Thus never use these eyebolts to lift the motor with additional loads coupled to it. The
lifting eyebolts of the terminal box, fan cover, etc., are intended to handle only these parts when
disassembled from the motor. Additional information regarding the maximum allowable angle-of-
inclination is indicated in the general manual available on the website www.weg.net.
