Wound Type Motor

Brief Introduction

 

YRKS series wound type motor proper adopts box-type steel plate welding structure with light weight and good rigidity. This series of motor has advantages of compact structure, light weight, high efficiency, energy-saving, low noise and vibration, high reliability, long service life and convenient installation and maintenance, etc.

At least six embedded temperature detectors (ETD) shall be supplied in accordance with IEC 60034-1. For directly cooled generators, it is important to note that the temperature measured by ETD is no indication of the hot-spot temperature of the stator winding.

Observance of maximum coolant temperatures given in item 1 in Table 11 of IEC 60034-1 will ensure that the temperature of the winding is not excessive. The limit of permissible temperature measured by ETD between the coil sides is intended to be a safeguard against excessive heating of the insulation from the core. The ETD temperature readings may be used to monitor the operation of the cooling system of the stator winding.

The number of temperature detectors measuring the coolant temperature where it enters the generator shall be agreed upon. For generators with direct cooling of the stator winding, the temperature of the cooling medium at the outlet of this winding shall be measured with at least three temperature detectors. These detectors should be in intimate contact with the coolant. Therefore, if the winding is gas-cooled, they should be installed as close to the exit duct from the coil as is consistent with electrical requirements. If the winding is water cooled, they should be installed on the piping inside the generator frame or as near as practicable to where the coolant leaves the frame, care being taken that there is no significant temperature difference between the point of measurement and the point where the coolant leaves the winding.
