Webb23 aug. 2024 · Slip ring induction motors are used for loads having high inertia, which results in very high rotor energy losses during acceleration. The slip ring induction motors are also used for loads which require a gradual build-up of load. They are used for loads that requires speed control. WebbIn terms of motor starting, a high inertia load is one that requires a relatively lengthy acceleration period before the motor achieves normal operating speed. Depending on the application, this acceleration period can often exceed two …
