The DC Motor Curve DC motor performance curves can be generated under various conditions. For example, the motor curve illustrated in Figure 1 was created using a rapid test on a motor dynamometer. The test was done by quickly loading the motor from no-load to locked rotor (stall) using a fixed terminal voltage from a power supply with low output impedance. A test like this is done to get .

Wound motors are suitable for application with heavy starting duties such as ball/sag mills, crushers etc. Typically LRS in these situations are used to start only, and when motor has reached a certain speed, the rotor is short circuited and it acts like an squirrel cage motor. Some manufacturers offer brush lifting systems, which will raise the slip ring brushes when motor reaches nominal ...

A wound-rotor motor, also known as slip ring-rotor motor, is a type of induction motor where the rotor windings are connected through slip rings to external resistance. Adjusting the resistance allows control of the speed/torque characteristic of the motor. Wound-rotor motors can be started with low inrush current, by inserting high resistance into the rotor circuit; as the motor accelerates ...
