Mechanical Features

 
Standard Features

Body : 63 to 100L Motor frames are available in cast iron as well as aluminum constructions. 112M to 225M Motors Frames are in cast iron constructions only.

End Covers : All end covers and flanges are with integrated bearing housings and of Cast Iron construction.

Terminal Box : Terminal boxes from 63 to 132M frames are of aluminum or Cast Iron construction with Aluminum pressure die cast terminal box with covers. All other frames are with Cast Iron construction with cast iron terminal box covers.

Cable Entry : Except 80 frame are aluminum constructions, all terminal box can be rotated in step of 90 Degree and are provided Metric threads for cable gland. Other threads like PG, B.S. Condute can be provided.

Shaft : Shafts are manufactured with of EN 8 steel with a taping in the center to secure pulley or similar types of mountings. Shafts with special diameter and length, with specified shaft material can be manufactured.

Bearings : Single Row Deep Groove Ball Bearings of internationals brands like SKF, TATA, FAG are used on driving end as well as no riving ends.

 

Lubrication : “ELCEN” motors are fitted High Temperature grease of Lithium Complex soap type, NLGI 2 no, in the bearings, for optimum performance and longer bearings life. (Castrol LCG-2) for high temperature H class insulation motor with molykott-41 high temperature grease in Bearings

Sealing : “ELCEN” motors are fitted with “V” rings for protection at the shaft and the rubber gaskets at terminal box and terminal cover. Oil seals can be provided instead of “V” rings on the shaft on request.

Mountings : Standard motors are available with either B3-Foot mounting, B5-Flange mounting. Special mountings can be manufactured suitable to customer’s requirements.

Noise Levels : “ELCEN” motors are designed and manufactured to perform silently. The noise levels are within the limits as per EN 60034-9

Balancing and Vibration : All rotating parts, mainly rotor with shaft are dynamically balanced to grade 2.5 for smooth running. However precession grade 1.0 can also be offered if required. Vibration levels of “ELCEN” motor are within the limits as per EN 60034-14.

The degree of protection as classified in IS 4691 is given below. It is denoted by two digit. The first digit denotes protection against solied bodies or particles and the second digit denotes protection against liquid. All our standard TEFC motor have degree of protection IP 55, unless otherwise specified.
 
 
Permissible Radial Load
 
 

The Output Shaft of the motors
can be subject to Radial Loads which depends on the type and size of pulley/pinion and also type of driven machine.

The extent of which can be calculated
with the following formula.

 
  R =
p x 973 x kW
RPM x D/2
  + Wt
Where R

weight of the pulley / sprocket / gear.
 
DEPENDING ON THE APPLICATION THERE MUST BE TWO CASES FOR RADIAL LOADS.
 
 
 
 
Load applied on shaft at
Mid-Point as shown above
 
Load applied at X distance from shaft
shoulder as shown above
 
 
For radial loads other than those recommended in the Table below customers are advised to consult Elcen machines Pvt. Ltd. For maximum allowable loads.
 
 
Installation Positions
Different applications demand different installation positions. It is always better to keep to keep in mind the installation position and the type of load while selecting the motor. However be construction and general arrangement of motors remains same for almost all installation positions.
 
MOTOR INSTALLATION POSITIONS
 
Selection of Motors
The kilowatt requirement of the motor can be obtained by the following formula
1. For horizontal motion   2. For rotary motion
 
PL =
F x V
102 x L
   
PL =
M x N
974 x Eff.
 
Where:
PL = Kilowatt required
F = Max total load in kg
V = Hoisting speed in Mtrs / Second
L = O/A eff. Of the driving unit:
   
Where:
M = Torque for movement in kgm
N = Motor speed in RPM
Ensure the rated output of motor is greater than the power PL
