Slip ring motors to increase energy efficiency Slip ring induction motors are in more detail, where large plants have to be operated: for example, the extraction of minerals, but also the production of cement, lime and plaster or the operation of crushers, roller presses and mills. In all these circumstances, while a different type of motor would use very high power and consumption to operate the systems, the slip ring induction motor and ring collector modulate the power and consumption and gradually start the machinery. Not only that, but with an asynchronous slip ring motorcombined with an inverter, the start-up consumption can be further reduced. Ultimately, like all motors by OME Motors, the OMA high voltage electric motors also represent the ideal solution for optimizing energy consumption, protecting the environment and saving on operating costs. Advantages of a slip ring induction motor OME Motors’ slip ring induction motors have a welded sheet steel structure as standard, which allows a light structure and increases the rigidity of the motor. The stator and rotor are precision molded in one piece to reduce energy loss and therefore improve the quality of the output. In slip ring motors of the OMA high voltage series, the stator coil is double-layered and the core is stacked and assembled with coils on the outside of the frame, applied on the circumference of the ends of the stator coil with spacers to improve rigidity. Once completed, the stator winding is placed in a vacuum tank, impregnated and inserted into the stator frame. The standard design of the rotor in wound rotor induction motors / slip ring motors and ring collector is made with a copper or copper alloy bar. Ring or forced oil for slip ring motors 2-pole slip ring induction motors from 355 to 450 H and all motors from 4 to 12P adopt anti-friction bearings, self-lubricated with grease or oil, based on the size of the motor frame and operating speed. The split sleeve bearings are suitable for 2-pole motors from 500 to 630 H, on request they can be lubricated with ring or forced oil depending on the load. To inhibit vibrations, the rotor cores of the asynchronous slip ring motors shrink on the shaft and the rotor coils are firmly inserted into the slots. The advanced brazing technology of the wound rotor coils ensures high mechanical resistance and good electrical conductivity at the joints.
