Introduction
Y-H series are totally enclosed, fan cooled three phase marine motors of the squirrel-cagetype. The motors are suitable for driving various machines on ships such as pumps, blowers, separators, hydraulic engines and other auxiliary equipment.
Y-H series is a design variation of the brand new Y series developed recently and noted for its high efficiency and starting torque.
The motors are designed accordance with National Standard GB755 Rotating electrical machines rating and performance and the existing “Rules for the construction of sea-going steel ships”.
The motors also comply with the relevant requirements of the following standards and specifications.
IEC60034 Rotating electrical machines
IEC60068 Basic environmental testing procedures
IEC60072 Dimensions and output ratings for rotating electrical machines
IEC 60092 Electrical installation in ships
The Motors are also in conformity with part of the specifications of the following ships classification societies.
LR: Lloyd’s Register of Shipping
GL: Germanischer Lloyd
NK: Nippon Kaiji Kyokai
Construction
Protection IP44
Frame, end shield and bearing cap
All made of Grey cast iron HT(GB/T9437) and the outer surface of the frame is provided with longitudinal cooling ribs to increase cooling effects.
Shaft extension
Standard motors have a cylindrical shaft extension. Motors of B3 and B35 with two shaft extensions are afforded on request, but the second shaft extension can only transmit rated output with direct coupling. The shaft is made of high grade steel No45(GB/T699).
Terminal Box
The terminal box is arranged at the “right hand side” when looking at the driving end. If the terminal box is to be arranged at the left-hand side. This fact must be specifically stated when placing the order.
Six terminal studs are provided in the terminal box and a connecting diagram is shown on the back of the cover. Terminal marking used are in full conformity with IEC publication 60034-8. Clearance between two neighboring conducing parts is made not less than 8mm and all creep ages not less than 12mm.
An extra terminal is provided inside the box for grounding purpose.
