Which type of slots are used in the construction of large size and small size induction motors respectively?
A. open slots and semiclosed slots B. semiclosed slots and open slots C. open slots and open slots D. semiclosed slots and semiclosed slots
Explanation: Large size motors use open slots, so that already prepared and properly insulated coils can be inserted in open slots. Small size induction motors use semiclosed slots, so as to reduce the effective gap length between stator and rotor. 2. In which of the following applications, wound rotor type of induction motor is used?
