## ETAP Motor Starting Study for 600kW Ball Mill Electric

Jun 27, 2020 The problem with ball mills vs a simulation like ETAP is that the mill initially is a torque load that is dependent on rotation angle until the charge start to tumble ETAP only simulates the torque vs speed as a curve Best bet would be to use a torque peak right off zero speed and then drop down to a more constant torque type of load curve

## Replacing slipring with induction motor Electrician Talk

Sep 24, 2014 JRaef said: It may not be as simple as a 1:1 HP replacement, you really have to analyze the torquespeed requirements of the Ball Mill before making that decision A VFD on a standard induction motor is good at making sure the motor can supply a CONSTANT level of torque regardless of speed But WR motors are capable of providing higher than
