Hollow core induction motor
NettetThis performance is achieved by substituting for the conventional design of a squirrel-cage rotor a new 2-part rotor consisting of an outer low-inertia hollow rotor constructed in the form of a thin magnesium sleeve that surrounds the iron core needed to complete the magnetic circuit efficiently. NettetInduction motors are primarily classified into two categories based on the power supply they are operating, i.e., Three-phase induction motor and single-phase induction …
Hollow core induction motor
Did you know?
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type. NettetThe common methods used to start induction motors are: (i)Direct-on-line starting (ii) Stator resistance starting (iii)Autotransformer starting (iv) Star-delta starting (v)Rotor resistance starting How slip ring motors are started? Slip ring motors are invariably started by rotor resistance starting.
NettetInduction motors are available in two types: single-phase (capacitor run) and three-phase induction motors. With the single-phase motor, the starting torque is generally … Nettet10. okt. 2024 · Induction motor (IM) is widely used in industry and home appliances.
