Slip ring motor construction

This article is devoted to slip ring induction motors. As discussed earlier, a slip ring induction motor is an asynchronous motor , as the rotor never runs in . A Slip Ring induction motor can be started with external resistance added in its rotor circuit. But how does external resistance aid in better starting characteristics ? Read here to know about the starting arrangement and the role played by the external resistances in obtaining better starting characteristics.

The slip ring induction motor could be used for industrial wires where variable speed and high starting torque are prime requirements.

The stator of slip ring induction motor is very much the same as that of the squirrel cage induction motor , but the construction of its rotor is very much different.

Also called rotary electrical interfaces, rotating electrical connectors, collectors, swivels, or electrical rotary joints, these rings are commonly found in slip ring motors , electrical generators for alternating current (AC) systems and alternators and in packaging machinery, cable reels, and wind turbines. However, no power is applied to the slip rings. Their sole purpose is to allow resistance to be placed in series with the rotor windings while starting.

The rotor is connected to the mechanical load through the shaft. Depending upon the type of rotor construction used the three . One of the major difference between the slip ring and the squirrel cage motor is that the slip ring motor has an external resistance circuit for controlling the speed of. The construction of the slip - ring motor is complicated because it consists slip ring and brushes whereas the construction of the squirrel cage motor is simple. In the motor the slip rings , brushes are provided.

Compared to squirrel cage rotor the rotor . Three phase slip ring induction motor my tech info. Slip ring induction motor bright hub engineering. This arrangement provides for easy access and slip ring induction motors . How does an Induction Motor work ? Types of Rotors - Different types of Rotors and their characteristics - Duration: 5: 20. Himanshu Srivastava 10views. Rotor is provided with 3-phase, winding consisting of coils used in alternator, The.

Cylindrical laminated core rotor with heavy bars or copper or aluminium or alloys are used for conductors. With their small construction volume, small space requirement and low weight, the special feature of our rugged asynchronous slip ring motors is their compact construction. Because cover and motor housing are decouple they are easy to service and install.

Thanks to the modular design of the cooling system, they can be . In slip ring induction motors the rotor is wound type.
