Product Description

W51 Electrical WEG Ac Motor Engine Generator Spare Parts1. Available Versions
The W51 HD motors are three-phase asynchronous motors with a squirrel-cage rotor, fully enclosed. This line is available in IEC 315 to 450 and equivalent NEMA frames, in low and medium voltage (up to 6.6 kV). Motors above 6.6 kV up to 11 kV can also be supplied upon request.
2. Standards
W51 HD motors are designed in accordance with IEC EN 60034-1 standard. They also meet the requirements and recommendations of other standards, as indicated in Table 1.
W51 Electrical WEG Ac Motor Engine Generator Spare Parts3. Environment
Unless otherwise specified, the rated outputs shown in the electrical data tables in this catalogue refer to continuous duty, S1, according to IEC 60034-1 and under the following operating conditions: g Ambient temperature range from -30 °C to +40 °C. g Altitudes not exceeding 1.000 masl. When the operating temperatures and altitudes differ from those indicated above, you must apply the derating factors indicated in Table 2 to determine the useful power output (Pmax).
Pmax = Pnom x Derating Factor
W51 Electrical WEG Ac Motor Engine Generator Spare Parts4. Construction Details
The information contained herein refers to the standard mounting features and the most common variants of the W51 HD line. Motors for special and/or customized application are also available on request. Please, contact the nearest WEG office.
4.1 Frame
roduced in cast iron FC-200, the frames of the W51 HD motors withstand high mechanical impacts, ensure maximum heat dissipation and high mechanical strength and reduce mechanical vibration even when transmitted by external sources. In addition, fins are distributed to have a greater heat dissipation area in the frontal area, which contributes to a uniform temperature distribution throughout the whole motor and reduces the DE bearing temperature. Thus, this unique fin distribution design ensures excellent thermal performance of the motor.

W51 HD motors have longitudinal fins that ensure better thermal dissipation and solid and integrated cast feet which provide greater strength (see Figure 2).
4.2 Eyebolts
To facilitate lifting to the different mounting positions, the W51 HD motors have multiple points for attaching eyebolts.
Motors with feet: Standard: five points for attaching eyebolts. Optional: nine points for attaching eyebolts (the five standard points plus four additional points - two on each motor foot).

Motors with two terminal boxes are provided with three main points for lifting eyebolts (two on the back and one in the center).

Footless motor: Standard: nine eyebolts (five at top side and four at bottom side). Optional: nine standard eyebolt fixing points plus and one additional eyebolt fixing point located at the bottom side center.

Note: g Horizontal motors: For lifting of horizontal mounted motors use all eyebolts simultaneously. For this procedure, there are two ways: vertical chains (see Figure 7) and inclined chains (see Figure 8).

For lifting motors with inclined chains, the maximum inclination angle of the chain during the lifting process should not exceed 30º in relation to the vertical axis. We recommend to use a spreader bar for maintaining the lifting elements (chain or ropes) in vertical position and thus preventing damage to the motor surface.

Vertical motors: For lifting of vertical mounted motors always use the eyebolts mounted at the top side of the motor, diametrically opposite, considering the mounting position (see Figure 9). In these cases, it is also necessary to use a spreader bar

Motors with two main terminal boxes: For lifting of motors with two terminal boxes, use always three eyebolts as shown in Figure 10.
