STARTING OF WOUND-ROTOR INDUCTION MOTORS electric

2017-04-05  A wound-rotor induction motor is built for heavy load frequent starts and (or) limited speed control motoring or generating at large power loads (above a few hundred kW). Here we insist on the classical starting method used for such motors: variable resistance in the rotor circuit (Figure 8.8). As discussed in the previous chapter, the torque/speed curve changes with additional rotor ...

What is a Wound Rotor Motor and How Does it Work?

2021-03-11  Though expensive and less efficient, the wound rotor motor and its adjustable torque-speed characteristics are great for driving large ball mills, large presses, variable speed pumps, cranes, hoists, and other high inertial loads. They also are great for any application that desires smooth startup and the ability to change speeds. They cover the bases that other induction motors cannot, and ...

Wound Rotor Induction Motors AC Motors Electronics ...

2015-02-12  The heat generated during starting is mostly dissipated external to the motor in the starting resistance. The complication and maintenance associated with brushes and slip rings is a disadvantage of the wound rotor as compared to the simple squirrel cage rotor. This motor is suited for starting highly inertial loads. A high starting resistance makes the high pull out torque available at

Wound Rotor Repair Tips: Testing, Application and Failure ...

a wound rotor motor can be used in a pumping applica-tion to reduce speed and, therefor flow. WHAT ABOUT THE SECONDARY VOLTAGE? One of the first differences noted, before even disman-tling a wound rotor machine, is the “secondary voltage” (and secondary current) reported on the nameplate. That label leads to understandable confusion about how a wound rotor motor actually works ...

Lrs Principle - Motor Starting - LMPForum

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 ...
