Answer / glenn saldanha savio

SINCE BOTH FIELD AND ARMATURE ARE CONNECTED IN SERIES THE
TORQUE EQUATION IS T=KI2. (TORQUE PROPORTIONAL TO SQUARE OF
CURRENT).
ALSO NOTE THAT FROM THE CHARACTERISTIC IT IS THAT AS SPEED
INCREASES THE TORQUE DECREASES AND VICE VERSA.
THEREFORE THE TORQUE IS HIGH ONLY AT LOW SPEED.

Answer / ajay k mathew

in a series motor same high current flows through the field winding and armature,therefore high starting torque

Answer / utkal mishra

we know in series motor t=flux*armature current
as flux directly propertional 2 armaturecurrent

I have a question, I visit 01 site and face a problem, there is 2.5 ton Air Con working, when air con compressor is running at that time rectifier voltages are increasing upto 290-295 v and rectifier is giving main high alarm (rectifier is APC single phase, before starting compressor rectifier voltages was 230v. when air con is going off rectifier voltages are decreasing smoothly at its actual voltages 230v. Load on Genset phases is this: Red-13.5 amp AC (Air Con load), Yellow-1.7 amp AC (BTS lights etc.) and Blew-4 amp AC (telecom system load), Genset phase to phase and neutral to phase voltages are also ok. These are 10 sites having same system and same rectifier APC brand at every site 02 genset are working but the problem is same at all these 10 sites. What will be the reason behind???
