Domestic uses: Small universal motors of the series type are used in domestic appliances like vacuum cleaners, refrigerators, washing machine, fans etc.
Grinding and milling machine: Up to 50 h.p. the motors may be D.C. shunt or induction with slip-rings and arrangement for pole-changing with cage rotors.
Planners: There is cutting stroke and a quick return stroke. Arrangements for reversing the speed have to be incorporated. A D.C. compound motor may be used.
Punching and shears: On account of heavy fluctuations of load, a flywheel is provided. The motor may be D.C. shunt or compound or slip-ring induction type.
Cranes and Hoist Work: For cranes D.C. motors of series or compound type are preferred as they have a high starting torque and the speed control is smooth. Induction motors are also used for hoisting.
Lifts: duty involves high acceleration and high retardation. The motor armature must therefore be light and it should run at moderate speeds .D.C. compound, slip-ring induction, induction-repulsion motors are used.
Textile Industry: Motors must be of totally enclosed type to prevent particles of the material being manufactured from getting into them. They should also be moisture proof on account of damp atmosphere inside a textile plant. Three-phase motors are used since their speed is fixed by the supply frequency. D.C. motors cannot be used as their speed varies with voltage.
Printing machinery: As it requires a variable speed Induction motors using rotor resistance may be used. Where large speed variations are required D.C. compound or A.C. commutator motors may be used.
Paper Industry: Synchronous motor is used as in this a constant speed of operation is required for giving a uniform thickness of the paper. Where speed is not required to be constant, squirrel cage induction motors or D.C. motors may be used.
Iron and steel Industry: D.C. shunt motors with flywheel arrangement or induction motors with speed control are used in such Industry.
Mining work: Flame proof motors are required for safet6y considerations in amines for which cage motors are used up to 10 hp and for large output slipring or D.C. motors are used.
