ELECTRICAL DESIGN
As standard, SGA motors have the following design and operating paramaters. Performance data is based on this standard. Any deviation should be examined and performance values altered in accordance with the information provided in this section.
Three Phase, 415V, 50Hz
Ambient cooling air temperature, 40 degrees C
Altitude - 1000m
Duty Cycle - S1 (continuous)
Rotation - Clockwise viewed from drive end
Connection - 240 Volt Delta/415 Volt Star (3kW and below)
Connection - 415 Volt Delta/720 Volt Star (4kW and above)
VOLTAGE AND FREQUENCY
Standard SGA motors are designed for a power supply of three phase 415V, 50Hz. Motors can be manufactured for any supply between 100V and 1100V and frequencies other than 50Hz. Standard SGA motors wound for certain voltage at 50Hz can also operate at other voltages at 50Hz and 60Hz without modification, subject to changes in their data. (Please phone for details as listed in the SGA manual)
SHAFT
SGA motors have standard shaft extension lengths and are provided with standard key, and drilled taped hole. Non standard shaft extensions are available upon special order, with shaft design outlined on a detailed drawing
Shaft extension run out, concentricity and perpendicularity to face of standard flange mount motors, comply with normal grade tolerance as specified in IEC 60072-1 and AS1359. Precision grade tolerance is available on special order.
