Figure 4 - Eyebolt fixing points for lifting motors with two terminal boxes. Figure 7 - Lifting with vertical chains. 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. J 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...

Motors with two main terminal boxes: For lifting of motors with two terminal boxes, use always three eyebolts as shown in Figure 10. J Figure 10 - Lifting of motors with two main terminal boxes. 2.3 Grounding Terminals The W50 motors are fitted with grounding terminals on the frame (see Figure 11) and inside the main terminal box. These terminals can be positioned on the right or left side of the frame and have cross-section from 25 to 185 mm2. The motors can optionally be supplied with an AEGIS shaft grounding ring (see Figure 13) installed on the inner bearing cap for external use can be...

2.5.2 Accessory Terminal Box The W50 motors have a specific terminal box for connecting accessories. This box is also manufactured in cast iron FC-200 and comprises two compartments (see Figure 18). Figure 15 - Terminal block for low voltage motors with six terminals. High voltage motors are supplied with three connection bolts and are supplied with terminal block as standard (see Figure 16). Figure 18 - Accessory terminal box. 2.6 Stator Winding The stator windings of the W50 motors, regardless of voltage, are supplied with Class F insulation system and Class B temperature rise (80 K)....

contamination of the impregnation varnish and ensuring voidfree impregnation of windings. For motors that operate with a non sine wave frequency inverter, insulation systems are reinforced to prevent accelerated aging of insulation (available on request). 2.7 Endshields To improve heat dissipation and ensure lower operating temperatures on the bearing, the DE endshield is provided with fins uniformly distributed. The endshields are manufactured in cast iron FC-200 and fastened with 8 bolts to ensure maximum rigidity (see Figure 20). 2.9 Fan Cover The fan covers are built in cast iron FC-200...

2.11.1 Main Nameplate The main nameplate provides information describing the mounting features and motor performance. It also iprovides the motor serial number and its year of manufacture. Figure 28 shows the layout of the nameplate on the W50 motor. It is noteworthy to mention that for proper motor operation air inlets for motor ventilation are not blocked and that the space surrounding the equipment is enough to keep the air temperature at the baffle inlet below the maximum temperature indicated on the motor main nameplate. For motors installed outdoors ensure that ventilation openings...

3. Ventilation System/Noise Level/ Vibration 2.11.2 Additional Nameplate To indicate the available accessories, the W50 motors are supplied with additional nameplates that contain informations on temperature sensors (see Figures 29 and 30), space heaters (see Figure 31), and other accessories supplied on customer request. If required, these nameplates can be used to show the TAG codes specific to the motor. Figure 29 - Additional nameplate for winding temperature detectors (Pt-100).

Figure 34 - Radial fan with straight blades.. The sound pressure levels shown in the tables above are valid for motors operating with no load and sine-wave power supply. Under load, IEC 60034-9 specifies a sound pressure level increase according to Table 5. Table 5 - Maximum expected increase of the sound pressure level for motors operated with load. Note: ■ The sound pressure level increase for motors driven by frequency inverter that depends on the switching frequency of the inverter, may reach up to maximum 11 dB (A) according to IEC 60034-17 and IEC 60034-25. 3.3 Vibration The vibration...

Table 7 - Maximum relative shaft displacement. another on the opposite side of the air baffles. In case of changing the terminal box position (in example, to change the mounting from B3L(D) to B3R(E)), the position of the air baffles and the threaded adapters for vibration monitoring should also be inverted. Optionally, these holes can be supplied with a threaded adapter for fitting the SPM vibration sensor (see Figure 37). Figure 37 - Threaded adapter for vibration measurement The frames also have flat areas for mounting of vibration sensors at the motor non-drive end. On request,...
