JR148-6 Wound Rotor Three-phase Asynchronous Motor 310KW/
Q: Doesn't the rotor get shorted out (maybe a small resistance) and it starts as an induction (wound rotor) motor? Just thinking out loud - If the starting SCR (I can't read the number - but the one associated with D1) were to stick on, that would short out the exciter, which would take out (short) two SCRs, (one on each side of the bridge ...

Ac Squirrel cage motors draw around 500% to 900% of Full Load Current (FLC) during starting. This might not pose a huge concern when starting motors with low kilowatt (kW) ratings but as soon as one starts talking about mill drive applications where the installed motors are generally in the range of 800 kW up to 15 000 kW, it does become a concern.

motor, it has associated complications on a wound rotor induction motor, especially if driving a grinding mill. A locked rotor condition has been found more commonly at Mill Safe Start sites than would have been suspected, due to problems with barring/inching gear interlocks or main gear problems. Without the Mill Jammed protection, the
Several of these are being considered today. Or, this arrangement is powered by two low-speed, high-torque synchronous motors with wound-rotor soft-starting windings and rheostats, and equipped with a quadrature-axis, load-share regulator for higher frequency response. Two of these at 9200 HP each are just being put into service.

I have working with a 4.16kV wound rotor motor with the rotor connected through slip rings to a rheostat during starting. Obviously after the motor has started the leads coming from the rotor are shorted together in the rheostat. My question is after the rotor leads are shorted together is there still voltage and current on these leads.

Motors considered are the squirrel cage motor, wound rotor motor, and synchronous motor. One important advantage of the synchronous motor is the possible correcting of power factor within your operation, through its use. When using a synchronous motor we recommend having 200% starting torque, 120% to 130% pull-in torque, and 225% pull-out torque.
Ours is 4160v and the stator induces the rotor to about 1500vac through a slip ring to the resistor bank. The motor starts with all resistors in parallel, each contactor "step" has a contact in an oil bath to each resistor bank, each step takes like 5 seconds until all the resistors have been removed and the rotor is shorted.
