C.R.I. A.C. Induction motors are suitable for continuous duty. Motor stator is made of low watt loss steel laminations assembled under pressure, rigidly locked in the frame. Dynamically balanced rotor ensures vibration and noise free operations. The varnish-impregnated windings are made of high-grade enameled copper wire which offers excellent resistance. Shaft is made of high quality steel, precision ground of sample size for transmitting the rated horsepower. Construction of motor frames and usage of quality materials result in high performance and low temperature rise thereby increasing the life cycle of the motor. Frame and end shield are of high grade cast iron machined to close limits for accurate alignment of bearings. In foot mounted motors, the frame and feet being a single molded piece completely enclosing the working parts of the motor. High quality bearings of heavy duty are fitted in housings packed with grease and are sealed against dirt and dust for trouble free operations. All single and three phase motors require an adequate motor protection control panel. |

Location | The location of the motor should be such that the motor is easily accessible for regular inspection and it should be relatively free from dust, fumes and moisture. These motors should be installed in a covered ventilated area, protected against the weather. Do not wrap the motor with air tight materials such as polythene sheet, rubber sheet, canvas cloth etc, as condensation will form in tightly wrapped motor and winding will burn out. The maximum ambient temperature should not exceed 40oC. | Special Features | Robust in construction, High operating efficiency, Highly durable, Less operational and maintenance cost. | Advantages | Industrial, Domestic, Agricultural | Tolerance on Encircled Di | Dimension | Tolerance | Specification | A.B. | 0.75 IS | IS : 1231 | H | 0.50 IS | IS : 1231 | D | J6 28 k6 38, 42, 48 | IS : 1231 | K | + 0.430 12, 15 | IS : 1231 | GA | 0.50 31,41,45,51.5 | IS : 1231 | F | 0.05 8,10,12,14 | Specification | d (centering) | | IS : 1231 |
