Slip Ring Motor Question & AnswersFebruary 27, 2023 By Wat Electrical This article lists 75 Slip Ring Motor MCQs for engineering students. All the Slip Ring Motor Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Slip Ring Motor.The induction motor with slip rings is used in high-power applications where high starting torque is required such as large pumps, compressors, fans, and so on. The slip rings are available in a variety of sizes and have high quality. The slip rings are reliable, cost-effective, easy to install, durable, has a short signal path, and are well suited to extreme environments. In phase wound induction motors or slip ring induction motors, we can easily add rotor resistance by using brushes and slip rings. The slip rings are used in robots, machine tools, capping machines, moving head projectors, video systems, CCTV systems, etc. The pancake slip rings have a low profile design, and a wide range of circuit options, and the main disadvantage is they have limited voltage and current capacity. In wireless slip rings no physical contact is required and has an unlimited number of rotations, limited bandwidth, and may be susceptible to interference. The fiber optic slip rigs are immune to electromagnetic interference, and it requires specialized equipment for termination. 1). In which one of the following motors, the distributed winding is used?
