Slip Ring Crane duty motor related issue

[rohitdewani]

Hello ,

I have a
60kW hoisting motor with 600 rpm ,10 pole ,crane duty slip ring motor

When the motor is started for its hoisting operation through resistance motor starts slow and immediately goes into full rpm having no sign of resistance.

Does anyone know what might be the reason for such a thing??
